Changes to the Garden’s entrance plantings

Garden Blog - Wed, 05/11/2016 - 10:35am

It is our responsibility as citizens, but especially as practitioners in the fields of horticulture and botanical sciences, to be good stewards of the land and ensure that what we are growing in our backyards and at the Chicago Botanic Garden will not contribute to problems in the future. That is why the Garden recently replaced the callery pears at the entrance to the Visitor Center.

In addition to the callery pear, the Garden also removed winged euonymus (Euonymus alatus) and tamarisk (Tamarix spp.).

One threat to our natural world is invasive plants. While many of these plants may on the surface appear to be attractive additions to the landscape, they can force out native species. Short of complete destruction of a natural area, I cannot think of anything more unsightly than a natural area that has been completely consumed by an invasive species to the point that it is no longer recognizable and holds very little biodiversity.

The list of invasive plants and potentially invasive plants is not set in stone; it is an evolving list and one that will continue to change as our climate changes. The callery pear (Pyrus calleryana) was not on the invasive species lists for our region a decade ago, but today it is in Illinois, along with Alabama, Georgia, South Carolina, and Tennessee. Most are familiar with the cultivar ‘Bradford’, but there are several others, including ‘Aristocrat’, ‘Autumn Blaze’, and ‘Cleveland Select’.

Garden staff plant non-invasive American yellowwood (Cladrastis kentukea) at the entrance to the Visitor Center.

This spring we replaced all of the Pyrus calleryana ‘Autumn Blaze’ at the front entrance of the Visitor Center with the non-invasive American yellowwood (Cladrastis kentukea). As a result, the front entrance is noticeably more open in appearance, and the low canopy and refreshing shade that existed in years past is now gone; it will return as the plantings grow.

Although both of these species are medium-sized deciduous trees with white flowers, the yellowwood has different ornamental characteristics. The callery pear flowers in the early spring, while the yellowwood flowers in late spring to early summer. The callery pear has unrivaled fall color in shades of red, orange, and yellow, while the yellowwood is one of the best for yellow fall color. 

Why is the callery pear called an invasive?

This pear has abundant seeds that can be carried by birds to natural areas. Plants can then become established, thus displacing native species. As land stewards, the Garden is very mindful of prohibiting and eliminating any plants known to be invasive in our region.

The new plantings at the Visitor Center entrance.

The new plantings at the Visitor Center entrance will take time to grow, but will someday provide the shade and fall color of their predecessors.

I have no doubt that some of these recently removed invasive plants were favorites among Garden visitors, our staff included. But sometimes what we like isn’t always good for us, or good for the environment.

New seasonal plantings replace the previous shrubs in the entry beds.

New seasonal plantings replace the previous shrubs in the entry beds.

I encourage you to review and continue to consult invasive species lists, including on the invasive.org website, and do your part by removing invasive species from your garden and resist purchasing and adding more. There are so many benign, beautiful options available to gardeners, and the Garden, along with numerous other organizations, has done the work for you by listing alternatives for the invasive plants that we feel we cannot live without. View a list of our recommended alternatives to invasive plant species here

Each of us can play an important role in preserving the natural landscapes for future generations.

Baltimore Oriole: Suburban Garden Songster

Birding - Sat, 05/07/2016 - 8:32am

In early May, when the leaves of maples are unfolding into a soft green, the Baltimore oriole (Icterus galbula) returns, giving his liquid “tea-dear-dear” song in suburban yards and forest preserve edges.

Homeowners who put oranges and grape jelly in feeders are often rewarded with a look at the male with his black head and back contrasting with his brilliant orange breast as he eats a spring meal.

Later, the female, with a dusky-colored head and yellowish-orange breast, will come. If she sees some 12-inch-long soft strings of light-colored yarn put out by humans, she may snatch them to make her nest. A common breeding bird of open woodlands, natural spaces, gardens, and parklands, the oriole has returned from its winter in the South: Florida, the Caribbean islands, southern Mexico, Central America, and northern South America.

By May, Baltimore orioles have arrived in the eastern United States to set up breeding territories. To get her attention, the male hops around the female, spreads his wings, and bows forward. The female responds by fanning her tail, fluttering her wings, and chattering. The female weaves plant fibers including grapevine bark, grass, and other materials such as yarn (and even horsehair) to build a hanging, pendulous, pouch-like nest. Typically, orioles nest about 20 to 40 feet high at the end of a branch. Their preferred locations are on cottonwoods, American elms, and maples.

In his Life Histories of North American Birds series, Arthur Cleveland Bent noted that the oriole is “perhaps the most skillful artisan of any North American bird.” Those lucky enough to see an oriole nest will most likely agree. It can take a week to ten days for the female to complete her nest. She’ll then lay three to seven pale eggs blotched with brown, which hatch in 11 to 14 days. The young remain in the nest for another 11 to 14 days, getting fed constantly by their parents, until they’re able to hop out onto a branch, exercise their wings, and then fledge.

These colorful birds eat insects, fruit, and nectar, (and grape jelly!), and can help keep populations of pests such as gypsy moth caterpillars in check. Agile members of the blackbird family, orioles can hang upside down and walk across twigs, or fly directly from perches to grab flying insects. Besides the “tea-dear-dear” song, orioles also give a series of chatters and scolding notes, which can alert you to their presence.

As summer goes on, the orioles seem to disappear, spending most of their time feeding young and less time singing and chattering. But come mid-August to early September, the orioles start singing again—often shorter songs—before they leave for winter vacation.

ExperiMINTing! with mint

Garden Blog - Fri, 05/06/2016 - 11:06am

With the Kentucky Derby—and mint julep season—approaching, it’s time to consider mint, a fast-growing, almost wonderfully invasive plant.

 Spearmint in bloom.

A refreshing digestive, mint can be harvested more than once in a season; use it fresh in your mojito, or dried as tea.

Mint survives Chicago winters and comes back hardier than ever. Cuttings easily take root and begin propagating anywhere they touch soil. For these reasons, grow mint in a plastic pot, so it doesn’t take over your yard. (The roots are so strong they can crack clay pots.) Mint needs at least four hours of sunlight per day, so pick a sunny spot. It is tolerant of most soils and weather conditions—just be sure it gets some water every week to keep it from becoming bitter.

Maintaining flavor

Mints spread in two ways: by runners and by seed. However, many plants are hybrids, which means the sprouts that shoot up from the broadcast seed will probably not be the same as the plant you bought. To keep that lovely flavor you brought home, trim the plants down when they have flowered, but before they drop seed. This causes the plant to bush out and spread from the roots only.

Choosing your flavor

 Mint julep by Bill Bishoff.

Mmm-Mmm mint julep—a Kentucy Derby favorite! Photo by Bill Bishoff

There are more than 600 types of mint on the market. Here are a few that work best in the kitchen:

Kentucky Colonel spearmint (Mentha spicata ‘Kentucky Colonel’) got its fame from being the leaf of the classic mint julep, but it’s also perfect for any mint sauce or jelly.

Banana mint (Mentha arvensis) is part of the spearmint family, but grown mostly for its incredible smell. It still maintains a good flavor in cooking, though.

Peppermint (Mentha piperita) is most often used for its peppermint oil. Peppermint family plants are strong flavored and best used dried or in small quantities because they contain menthol (think Vicks). They soothe stomachs, but are difficult to cook with fresh.

Variegated pineapple mint is a lovely, sweet-scented peppermint hybrid that makes a great tea. To keep it variegated, you need to cut off any green stems.

Orange mint is the most invasive of all mints, so plant accordingly. It smells sharply of orange peel and can turn a nice burgundy color during winter It also works beautifully in baking recipes.

Easy Mint Simple Syrup

 Mint simple syrup.Making simple syrup is a great way to put your mint to good use.

What you need:
½ cup mint of your choice (washed leaves; lightly chopped pieces packed down)
1 cup water
1 cup sugar

Directions:
Rinse and drain mint leaves. Bring water to boil in a small pot on the stove. Add mint leaves and sugar. Stir until sugar dissolves, and then turn off heat. Let mixture cool (approximately 30 minutes). Strain off leaves.

Store the syrup in the refrigerator for use within two weeks, or freeze for later use.

To use:
Add this simple syrup in place of sugar in your favorite ice cream, sorbet, lemonade, soda, or cocktail to add balanced mint flavor to any recipe. Even better, add to a dry wine or prosecco for an easy happy hour treat.

Want to take it higher? Freeze the syrups in ice cube trays with a few small leaves and use as a sweetener for tea or cocktails. A glass of bourbon becomes a Mint Julep when you add Mint Syrup ice cubes.

Peppermint Extract

 Peppermint extract.Peppermint oil is often used for cleaning, pest control or aromatherapy. What you produce is not the professional essential oil (that takes more time and effort than most of us can muster), it will do the jobs needed.

What you need:
A sealable/airtight jar or glass container
Enough chopped peppermint or peppermint family leaves to fill the jar
Vegetable oil, olive oil or nut oil 

Directions:
Place washed chopped mint leaves in the container (no need to pack; they need to breathe a bit). Heat the oil of your choice (use enough to fill the jar) on the stove in a small pan until it is too hot to touch. Pour the oil over the leaves and seal the container. Let the mixture sit on the counter until it has cooled, then move it to a dark place or cupboard for a week and a half to two weeks. Once it has set, strain out the liquid into a spray bottle.

Uses:
Peppermint oil sprays are said to prevent mold and can be mixed with vinegar to create a simple disinfectant cleaner. They also create a great air freshener, massage oil, or natural control against ants, mosquitos and even rodents.

 Tarragon simple syrup and fresh peaches enliven a sparkling wine cocktail.

Add simple syrup to Prosecco and peaches: lovely.

Spring It On—Spring Annuals for 2016

Garden Blog - Mon, 05/02/2016 - 3:18pm

Did the striking Silver Fox foxglove make it into “the show” this spring? Who decides which flowers make the cut anyway for the unfurling of 75,000 annuals at the Chicago Botanic Garden?

We’ll show you a few of our spring favorites that made it through the multi-level review process.

Digitalis purpurea ssp. heywoodii ‘Silver Fox’

“Behind all of these beautiful displays, there is a lot more happening than what you may think,” said Tim Johnson, the Garden’s senior director of horticulture. “It can be very complex—different plants have different production times.” Besides considering how long it takes for a plant to grow in our greenhouses, the Garden’s experts also consider the desired size and bloom time.

Every season, each horticulturist proposes a color scheme and submits plans to Johnson. About ten months before spring or the start of the other seasons, the proposals are reviewed by experts, including Kris Jarantoski, executive vice president and director; Tim Pollak, outdoor floriculturist; Brian Clark, manager of plant production; Andrew Bunting, assistant director of the Garden and director of plant collections, and Johnson. The team also considers how each proposed plant fits into a garden’s design and color scheme, along with its habit, culture, and cost. “They all need to be looked at globally to make sure there are different plants, varieties, and color schemes throughout the entire Garden,” Johnson said. “Each garden should have a unique look to it.”

So Classy: Spring Wreaths Made from Flowering Branches

Garden Blog - Thu, 04/28/2016 - 9:34am

Budding and flowering trees and shrubs—redbud, plum, spirea, almond—are among the great joys of spring. Under the calm and creative eye of Field & Florist’s Heidi Joynt, we learned to turn those branches into lovely, living wreaths in a perfectly timed class at the Chicago Botanic Garden.

Heidi Joynt demonstrated how to layer in curly willow cuttings and delicate flowering branches like bridal veil and bridal wreath spirea.

Sterling Range heather (Ciliatum 'Sterling Range') Flowering plum (Prunus cerasifera) Redbud (Cercis canadensis) Pussy willow varieties Flowering almond (Prunus triloba)

Spring blooming wreaths included “delicate” branches like those shown here.

A finished wreath incorporates many of the more delicate flowering shrubs with a central focal point of redbud and plum branches.

The finished wreath is an exuberant combination of the more delicate flowering shrubs with a dramatic central focal point of redbud and plum branches.

Most Chicago-area yards have a flowering shrub or tree, much admired when it bursts into bloom in spring. While some intrepid gardeners know to cut early branches to force bloom indoors, Joynt takes the idea in a different direction—in a circle, with living branches forming a perfect-for-the-front-door wreath.

Imagine walking out into your yard, pruning a cluster of branch tips—plus a large branch or two—then starting to fill in an 8- to 12-inch grapevine or curly willow wreath (purchased or handmade). That’s how surprisingly simple the process is.

As everyone clipped and pondered and designed, Joynt offered helpful wreath-making and wreath-tending tips:

  • Larger branches of redbud, crabapple, forsythia, double almond, or plum can be strategically wired onto the wreath to create a focal point. 
  • Add delicate curly willow or birch catkins at the center and the outer edges of your wreath. Bouncing and waving in the breeze, they add movement and interest to your design.
  • Hung on your front door, the living wreath can be spritzed with water once or twice a day to keep flowers fresh. 
  • As flowers drop off or brown, pull the branches out of your wreath and replace them with the next blooming items in your yard. Fresh flowers like tulips and roses can also be inserted by placing them in flower tubes (available at florists and craft shops) and tucking them into the wreath. 
  • Yes, silk flowers are an option. Joynt recommends www.shopterrain.com for extremely realistic flowering branches.

This Amazing Plant Changes Gender from Year to Year

Garden Blog - Wed, 04/27/2016 - 3:06pm

Amorphophallus remains a unique occupant in the world of plants, and visitors to the Chicago Botanic Garden recently experienced the fascinating bloom cycle with the titan arum Sprout. However, there is an additional denizen of the Araceae (a.k.a. Aroid, a.k.a. Arum) family with rare and exceptional attributes, which can be seen blooming this very moment at the Garden.

Japanese cobra lily (Arisaema ringens) has an uncanny, serpent-shaped, flower and possesses a remarkable ability to do something which few other plants can do: change its gender from year to year.

 Jack-in-the-pulpit (Arisaema triphyllum).

Almost anyone who grew up in an Eastern or Central time zone will recognize our native jack-in-the-pulpit (Arisaema triphyllum).

Arisaema species (jacks), are paradioecious, meaning the blooms of an individual plant can be male one year and female the next. Young plants will produce male flowers with pollen until they are mature enough to produce fruit. When they have accumulated enough energy to fruit, they will produce a female flower that will hopefully become pollinated.

However, after an exhausting round of fruit set, the plant may take a break and produce male flowers the next year. Producing pollen, rather than fruit, saves energy. Unhealthy conditions or damage to a female flowering plant can also cause it to produce male flowers the next time around.

Basically, Japanese cobra lilies change sex for a period of time to save energy and allow themselves time to recover. 

Like all species of Arisaema, the flowers of Japanese cobra lily have a spathe (pulpit) with a spadix (jack) inside. The pulpit is striped purple with white on the outside while the interior is a dark, shiny chocolate color. What is different about the blossom of Japanese cobra lily is that the hood of the spathe is curved and helmet-like, with the tip covering the front of the opening where which jack resides. This formation produces the startling look of snake eyes.

One of the first jacks to emerge in spring, cobra lily flowers can last eons in the cool spring weather.

 Japanese cobra lily (Arisaema ringens).

Japanese cobra lily (Arisaema ringens) appears early in the spring each year; the flowers will remain until the large leaves have fully extended, shading the bloom.

Fortunately, the blossom does not have the noticeable unpleasant odor that a corpse flower has, but it still manages to attract the flies and beetles that do their bidding. In physical appearance, Arisaema ringens is similar to our native jack-in-the-pulpit; however, the entire plant is more robust with a pair of giant, polished trifoliate leaves, creating an almost tropical appearance for a Midwest garden. The overall height is two feet tall. Female plants can produce bright reddish-orange berries in late summer and early fall, extending the show. 

As with most Arisaema species, Japanese cobra lily hails from China, Japan, and Korea. It is one of the easiest to grow, and perhaps the best garden subject for the Chicago area. They are pricey to buy; however, the flying saucer-shaped tubers will bulk up quickly in a rich woodsy soil.

There are warnings against growing them in heavy clay, but the Garden has terribly dense soils and our planting has performed nicely. Keeping conditions moist and shady in the summer will prevent an early dormancy. Another bonus is that Arisaema ringens are deer resistant because the leaves contain calcium oxalate crystals, which make them smelly, poisonous, and irritating to chew.

If you would like to see Japanese cobra lilies during your visit, just head down the lower woodland path of the Sensory Garden. You can also search for them via the Garden’s Plant Finder.

Ooooh-ooh That Smell…

Garden Blog - Tue, 04/26/2016 - 10:26am

On Tuesday, April 24, #CBGSprout raised a big stink at the Chicago Botanic Garden! Our day included these snapshots of the early morning visitors to the rare phenomenon of a corpse flower in full bloom.

We chatted with the early birds and met some “regulars”—visitors who had come by to meet Spike, the Garden’s first titan arum on display last August, and Alice, the corpse flower that bloomed last September.

Harper, 14 months old, waves at #CBGSprout the corpse flower.

Carrie Kirchen of Deerfield visited this morning, along with Maxwell, age 9, and Lexi, age 6.

Lexi: It smells horrible.

Maxwell: We found out on the Internet. The Internet knows everything.

Lexi: It’s very stinky.

Maxwell: It is a once-in-a-lifetime chance to see it. And it is very stinky.

Carrie: I happened to see the Facebook post. And we were here every day for Spike (a titan arum that previously was on display at the Garden).

Jamie Smith of Highland Park was here with Harper, 14 months old, as well as Susan and Jim Osiol of Mt. Prospect.

Jamie: We keep coming! Third time is the charm.

Susan: I’m obsessed. Our daughter called first thing this morning: ‘Mom, Sprout is blooming!’

Jim: It is vibrant. It’s a piece of nature that’s fascinating.

Emily Rosenberg of Highland Park was here when the doors opened at 6 a.m.

Megan and Daniel Ladror of Chicago analyzed the smell:

Daniel: This smells like our garbage at home after two days.

Megan: It’s such a rare event. I’m excited to see one without waiting in line.

Emily Rosenberg of Highland Park loved the bloom:

Emily: Beautiful. It is so interesting with the spathe (modified frilly leaf). It has great textures.

Schoolteacher Jody Schatz will have something to share with her class at Reinberg Elementary School in Chicago.

Michelle and Haley Nordstrom, who live five minutes from the Garden:

Michelle (who was watching the livestream at the school bus stop with her daughter when she realized that Sprout was blooming; they jumped in the car): I took a photo of Sprout and sent it to my daughter’s school and said, “We’re going to be late.”

Visitors Roberta Stack, Joanna Wozniak, and Apple, age 7:

Roberta: I’ve been watching it in the camera and saw it open. I ran right down.

Apple: Pretty smelly.

Joanna: I’m catching a cheesey whiff. A bit of Parmesan.

Apple: It does kind of smell like cheese.

Ten Things to Know About Corpse Flowers

Garden Blog - Wed, 04/20/2016 - 10:00am

The Chicago Botanic Garden is on #TitanWatch. That’s right: if you visit the Garden’s Semitropical Greenhouse, you will see Sprout, the latest corpse flower from the Garden’s collection of 13 titan arums to begin a bloom cycle. 

 in fruit, leaf, and bud.

Our corpse flowers (Amorphophallus titanum) are now on display in a variety of life stages: in fruit, leaf, and imminent bloom.

You might remember Spike and Alice in 2015: Spike failed to bloom but provided so much excitement; and Alice the Amorphophallus brought visitors to the Garden at all hours to see, and smell, a corpse flower in bloom. Now we are all watching Sprout to see if the corpse flower—known as a titan arum (Amorphophallus titanum)— will produce a huge, rotten bloom. Follow the progress of #CBGSprout on our corpse flower webcam and check our website for updates.

We learned a lot about corpse flowers in the last few months, and in the Semitropical Greenhouse, there are corpse flowers at three different stages on display: in the middle of a bloom cycle (Sprout); a non-blooming titan arum leaf; and a pollinated and fruiting titan arum (it’s Alice!). 

Here’s what you need to know as you watch Sprout grow:

  1. The corpse flower is one of the largest and rarest flowering plants in the world. It takes seven to ten years for a single corpse flower to produce a flowering structure (inflorescence). While other corpse flowers in cultivation have bloomed around the world recently, having more than one plant bloom in such a short time is uncommon. Watch for these signs the titan arum bloom is starting.
  2. Corpse flowers smell bad. Really bad. Peak stink time is usually very late at night.
  3. Speaking of night, that’s when corpse flowers usually bloom. And once they bloom, the bloom lasts 24 to 36 hours. Want a sneak peek? View our last titan arum bloom.
  4. If Sprout blooms, the Garden will stay open until 2 a.m. so visitors can experience the corpse flower bloom up close (last Garden entry will be 1 a.m.). Watch the live corpse flower webcam, check the blog (subscribe today), and follow the Garden on Facebook and #CBGSprout on Twitter to get the latest information. 
  5. Corpse flowers are BIG. In their natural habitats, they can reach 10 to 12 feet tall with a bloom diameter of 5 feet. In cultivation, they typically reach 6 to 8 feet in height, but all are different. 
  6. Corpse flowers are unpredictable. When the Garden was watching Spike, the first titan arum, even the horticulturists were surprised that the plant did not flower.
  7. Corpse flowers are native to Sumatra, but Sprout was grown here from seed the Garden received in 2008 from the University of California Botanical Garden at Berkeley. Learn about the titan arum’s native habitat.
  8. The corpse flower includes the corm, which may or may not go on to produce a flower; the spadix, which is the tall flower spike; the spathe, which is a single, frilly, modified leaf that enwraps the spadix; the petiole, which is the leaf stalk; and the branch-like rachis, which supports the many leaflets. Find more diagrams and information in our titan arum educator resources Titan arum leaf parts diagram.
  9. Corpse flowers that bloom in the wild attract pollinators like carrion beetles and flesh flies. Once the plant is successfully pollinated, it develops olive-shaped, red-orange berries. Read more about titan arum pollination.
  10. Corpse flowers need protection. The Garden’s conservation work ensures that plants like these survive and thrive. Studying seeds from Sprout, Spike, and Alice enables scientists and horticulturists at universities, conservatories, and other institutions increase the genetic diversity of the species. See how we are studying our titan arum fruit.

For Some Birds, Constructing a Nest Could Be a Stretch

Garden Blog - Mon, 04/18/2016 - 8:32am

While working out in the woods this winter, a small lump on the branch of a young elm tree caught my attention. At first I thought it might be a gall, or an injury that had healed-over. On closer inspection, the lump turned out to be a ruby-throated hummingbird nest from last summer. 

Although I see hummingbirds regularly at the Chicago Botanic Garden, I rarely encounter one of their nests. Hummingbirds themselves are amazing, but their nests are truly a marvel of avian architecture. Not much larger in diameter than a quarter, they are just large enough to hold the one to three navy bean-sized eggs of the hummer. For the pint-sized bird to be able to keep the tiny eggs warm during incubation requires that the nest be not much larger than her body. 

 Hummingbird nest and quarter (for scale).

Not much larger than a quarter, the ruby-throated hummingbird nest is an engineering marvel.

This is all well and good until the eggs hatch. Growing young hummingbirds can double or triple the amount of room necessary to hold the family. One of the ways the hummingbirds get around this need for flexibility is that they construct the nest of soft plant fibers and then wrap the whole thing with spiderweb silk. This creates an elastic nest that has the ability to expand as the contents of the nest increases. Can you imagine yourself going out and plucking a strand of sticky silk from a spider web with your fingers and then trying to use it to build something out of lightweight fuzzy plant fibers? I imagine you might find yourself wrapped up in a ball like some sort of oversized grotesque moth cocoon. The silk also helps to anchor the nest to the top surface of a horizontal branch.

 Spiderweb silk is used by hummingbirds as a nest liner.

Spiderweb silk: the expandable nest liner preferred by hummingbirds.

Keeping the nest just the right size as the need arises helps to keep the growing youngsters warm and secure. In the western states where several species of hummingbirds nest, often at higher elevations, it is not only important to keep the nestlings warm, but also the incubating female, especially at night. Therefore, it is often the case that hummingbirds in these colder situations will locate their nests on a limb with an overhanging branch acting as a sort of roof to help block the nest from the night sky. 

Although this measure helps reduce heat loss, it is often the case that nesting females will go into a state of torpor (reduced physiological activity to lower body temperature) in order to conserve energy on particularly cold nights. This is a principle of physics in which the larger the difference in temperature between objects, the faster the heat flows from the warmer one to the cooler one. Therefore, a hummingbird with a lower body temperature will lose heat more slowly than the one with a warmer body. As I stated earlier, hummingbirds are amazing!

 Parmelia sulcata, a common lichen, is used to help disguise the hummingbird's nest.

Parmelia sulcata, a common lichen, is used to help disguise the hummingbird’s nest.

Part of the reason—besides size—I had not noticed the nest earlier is that the birds do a fantastic job of camouflaging it. This also relates to the spiderweb silk. Some or all of the silk used is sticky. Upon completion of nest construction, the birds collect bits of lichen and attach them to the sticky strands on the outside of the nest. Interestingly, the birds seem to always use the same species of lichen, one that goes by the name of Parmelia sulcata. 

Parmelia sulcata is a light greenish-gray lichen with a leafy (foliose) appearance. One of our more common lichens, it is often seen on the upper branches of trees, and was particularly abundant on the ash trees that died from emerald ash borer. I don’t know if the birds chose this species of lichen in particular or, being common, it is just found most often. It is also interesting that the birds seem to apply the lichens to the nest in an upright position, with the top facing outward, so they look like they could be growing on the nest.

Come birding at the Garden! Take a birding class; join a group, and check your finds against our bird list.

Although this process is fascinating, it is not restricted to hummingbirds. One of the other breeding birds at the Garden utilizes a very similar nest construction technique to hold its three to five small eggs. The blue-gray gnatcatcher, another tiny bird (that somewhat resembles a miniature catbird in appearance and sound), also constructs a nest out of soft plant fibers, including spiderwebs, and applies lichen to the outside of its nest. A nest of this species, a little larger than that of a hummingbird, was found on a branch of one of the locust trees growing in a Garden parking lot.

Healthcare Garden Design Certificate Program

Garden Blog - Tue, 04/12/2016 - 12:58pm

In the summer of 2002, a large, multidisciplinary group of professors, healthcare providers, and design professionals gathered at the Chicago Botanic Garden to help form the curriculum of a new, original certificate program.

The goal of the Healthcare Garden Design Certificate Program was, and remains, to provide a useful, up-to-date, and engaging professional development opportunity in healthcare garden design that reflects the multidisciplinary nature of this emerging field, and allows participants the opportunity to focus their learning on topics of particular relevance to each person.

From the start, evidence-based design has been the core of this program, with a focus on using research results to design garden facilities that allow for and make possible specific health and wellness outcomes, while encouraging the design team’s creativity and the application of professional insight.

What you can expect to learn from attending this course:

  • Learn from key industry leaders why healthcare gardens constitute an essential component of customer-centered environments of care. Learn how these gardens positively impact patient health outcomes, stress reduction, and satisfaction, as well as employee retention, marketing activities, philanthropy, accreditation, and the bottom line.
  • Gain a more thorough understanding of how evidence-based design is fueling growth in healthcare gardens and restorative environments, and how research informs the design process.
  • Define best practices in this emerging field through collaboration with colleagues from a variety of professions.
  • Discover how healthcare gardens can lead to increased levels of outside funding and contribute to successful marketing activities.
  • Learn about the full range of benefits that therapeutic gardens make possible when used by health professionals including doctors, nurses, and horticultural, art, music, physical, occupational, and recreation therapists.
  • Engage in case studies, multidisciplinary group projects, field trips, and other learning activities that focus on the unique characteristics of healthcare gardens and their design for specific populations and facilities.
 Splitting into teams, each group designs their own Healthcare Garden Design project to present at the end of the program.

The Healthcare Garden Design (HGD) program at Chicago Botanic Garden was one of the most information-packed programs I have ever attended. Every speaker was at the top of their field and imparted practical, useful information that I was able to take back to my special-needs school to use. I loved that the speakers had diverse backgrounds—which gave a well-rounded view of what healthcare gardens should entail. Because of what we learned at the HGD program, we were able to design a wheelchair-accessible therapy garden that meets the needs of all our students. The program gave us insight to avoid problems, add security and safety, and create a useful, beautiful garden for students with very complex needs. I can’t say enough about how valuable the HGD program was for my professional career as a special-needs educator with an extreme interest in horticulture therapy.
—Janel Rowe, Bright Horizons Center School, Bright Garden Project co-chair

Each cohort is composed of up to 24 professionals and students from throughout the United States and abroad.

Past participants include:

  • Healthcare executives, administrators, and facility managers
  • Landscape architects, architects, and garden and interior designers
  • Nurses, doctors, horticultural and other adjunctive therapists, and other medical professionals
  • Graduate students in degree programs in these fields

Upon completion of this program, the participant’s ability to design and promote healthcare gardens will be markedly improved. Someone who has completed the program will be capable of applying their knowledge, skills, and insight to the design of healthcare gardens for any population or facility.

What you won’t find in the marketing material—the exclusive intangibles of this course—is the experience of immersive learning from the broad range of distinguished instructors, in a spectacular setting. The Chicago Botanic Garden itself is a masterpiece of great design, and the classroom feels like an illustrious museum. The curriculum and instructors provide personalized and customized learning. Participants have created enduring friendships and professional relationships in this course.

There is no other course like this one; the Healthcare Garden Design certificate program provides a unique and extraordinary experience.

Do-It-Yourself Seed Balls

Garden Blog - Sun, 04/10/2016 - 9:39am

Spring is seed season—and a good time to think about gifting seeds to gardeners, friends, and green-thumbed moms (think Mother’s Day, May 8).

Musing about how to share some of the seeds that she gathered at February’s Seed Swap, horticulturist Nancy Clifton got interested in the guerrilla gardening-inspired idea of “seed balls” (or seed bombs, as they’re sometimes called). While the guerrilla gardening movement leans toward stealth seeding, Nancy thinks seed balls make an ideal gift item—they’re easy to make, easy to “plant,” and an easy way to teach kids about germination.

 Seed balls made with different recipes.

Clay powder gives seed balls a reddish color and even texture; using clay chips makes a slightly chunkier, greenish seed ball. Both work equally well.

Here’s the easy seed ball recipe:

  • 1 cup powdered clay or potter’s clay (can be purchased online)
  • ½ cup dried compost (the finer, the better—Nancy used a pre-bagged compost mix)
  • 2 tablespoons desired seeds (see seed choice section below)
  • 1 tablespoon cayenne pepper (to deter critters from eating the sprouts)
  • Water

Mix the dry ingredients; then add ½ cup water. Stir, then begin to judge the consistency. Wearing gardening or plastic gloves, roll a teaspoon-sized ball in your hands (size can vary). Think “mud pie”—the ball should hold together when you squeeze it, without crumbling or dripping water.

Roll all of the mixture into balls; then let the balls dry on newspaper or waxed paper for two or three days. Don’t worry about smoothness—rustic-looking seed balls are as interesting as marble-smooth. The color will change to dark red/terra cotta as the balls dry. This recipe yields about 24 seed balls.

About Your Seed Choice

  • Less is more. You only want a few seeds to sprout from each seed ball. Too many seeds mean too many sprouts, resulting in too much competition for nutrients and water.
  • All sun. All shade. All herbs. All spring. Choose seeds with similar needs to maximize success in their container or garden spot. Nancy’s variations:
    • All summer annuals
    • All lettuces
    • All cool-season herbs
  • Use organic, non-treated seeds from your own garden or from trusted sources.
  • Choose native species for flowers and perennials that will grow successfully in our USDA Zone 5 region. Be responsible: do not use seeds from invasive species.

 Nancy handles finished seed balls using plastic gloves.

Wear plastic or latex gloves when making seed balls. The mixture tends to be very sticky, and clay can dry out your hands very easily.

Seed balls can be set into a container of potting soil (sink it down just a bit into the soil), or placed, randomly or intentionally, on bare soil in the garden. A rainy day is the perfect day to “plant” seed balls—rain helps to break down the clay and compost, giving seeds a good dose of food and water to get started growing.

Throw one in your garden. Fill an empty space. Gift a brown- or green-thumbed friend. And happy spring, everyone!

All-Season Nature Crafts for Kids

Youth Education - Wed, 04/06/2016 - 9:12am

As a mom and working artist, I try to think of ways I can introduce my 3-year-old daughter to the outdoors and the power of imagination through craft projects. And as an employee at the Chicago Botanic Garden, I am inspired by all sorts of family programs and drop-in activities for kids and families that celebrate the outdoors.

What’s fun about nature art is that it starts with an adventure and ends with a surprise. For instance,  the “family of owls” that we created may appear in story time later.

Here are some of the nature-inspired activities and kid-friendly crafts that have come out of my journey as a mother and continue to get the best reviews from Laila, my toughest little critic.

Dirt is cool

Even when she was a baby, my daughter was intrigued by dirt. She is still fascinated by it, in any form. In the long winter, when we’re tired of being cooped up, we bring a little of the outdoors inside and put together a mud pie prep kitchen. Supplies include dropcloth, potting soil, spray bottle, pouring cups, pie plates, and sticks, rocks and/or sand for decorating.

 Mudpie in progress.

Don’t forget to have an old towel underneath your creation station.

 Laila holds her finished mudpie.

Happiness is when mom says it’s OK to play with your food

This is the best way to distract a picky eater, or wow guests with an inexpensive dish you can design with your kids. Laila and I made these creations out of various fruits, vegetables, herbs, and cheeses.

 A cheese and fruit plate in a holiday theme is fun for kids to graze.

Bite-sized holiday snacks are great for kids who graze.

It’s an outdoors treasure hunt

Laila and I start by taking adventure walks and filling our pockets or a basket with sticks, leaves, flowers, and other found art objects. Everywhere you look, there are free art supplies.

Every season has something outside to explore.

Take gatherings inside to make nature scenes or collages inspired by the seasons. Here, onion skins provide the fall leaves for our tree painting.

Rock ’n’ roll with it

Hand-picked rocks can be collected, cleaned, painted, and polished to transform into precious stones with a story attached. Even little nature lovers can apply homemade or washable paint to their rocks before an adult adds a clear topcoat finish. The rock art can be used as a paperweight or embellishment to a potted plant. Add a pipe cleaner and clothespin to make it a photo holder.

Collected stones can be painted or polished as keepsakes. Here, we’ve added a pipe cleaner and clothespin for a photo holder.

Impromptu art

One day we found pine cones and added fabric, buttons, and ribbon to create a family of owls that found a new home in our Christmas tree. Another time we used sticks, wire, glitter, and beads to build a twinkling mobile.

A family of pine cone owls made great Christmas ornaments.

When the projects are done, we talk about what we made, where our supplies came from, and who we can share our creations with.

Some of my favorite childhood memories are of outdoor exploration with my mom. I hope Laila someday will feel the same way.

Want to get more nature into your child’s world? Join us for a Nature Preschool open house April 7, from 10 a.m. to 6 p.m.

Deeply Rooted: Garden educators, scientists, and horticulturists are made early in life

Youth Education - Mon, 04/04/2016 - 9:39am

A growing body of research tells us that children are better off when they have daily contact with nature.

Nature play encourages creativity and problem solving, boosts academic performance, helps children focus, increases physical activity, improves eyesight, reduces stress, and promotes positive social relationships. 

Chicago Botanic Garden scientists, educators, and horticulturists credit their personal growth and professional development to early doses of “Vitamin G” (a term used to describe the benefits of exposure to green environments). Their words and childhood pictures best capture the joyful effect of nature on their lives.

“Even though I spent the early part of my childhood in Hyde Park, Chicago, I can’t remember a time when as a family, we didn’t take every opportunity to head out of the city to northern Wisconsin, the Upper Peninsula, or northern Michigan for camping, canoeing, or hiking. Later, we moved to (almost) rural New York, where my sister, friends, and I became intimately familiar with the acres of woods, fields, and streams behind our house, disappearing for hours to explore our private, imagined world. As an adult, when I had the opportunity at the Chicago Botanic Garden to combine my expertise in learning science with my love of nature and share it with others, I thought, ‘This is the place for me.’”

“The more high-tech we become, the more nature we need.”—Richard Louv, journalist and author of Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder

“Some of my fondest memories of childhood include our summer vacations at Silver Lakes in southwestern Michigan. My brothers and cousins and I would spend all day, every day, playing in the sand and splashing in the water. We’d take the rowboat out to the ‘lily pads’ to see if we could catch any frogs—we were (disappointingly) never successful, though we did manage to get the rowboat stuck once for what seemed like an hour, but was probably just a few panicked minutes.

I have a particular fond memory of my close cousin Jean and I filling buckets with sand, mixing in just the right amount of water, and carefully making a batch of sand pancakes to cook on our folding chair stove. The simple pleasures derived from the freedom to play and explore outside throughout my childhood reinforces for me the importance of ensuring those same opportunities for play time in nature are available for my own children at home and the children participating in the programs at the Garden—making sure there are places to run, to hide, to dig, to splash, to have fun.”

Coordinator, family programs

“I grew up in suburban Pittsburgh, Pennsylvania, with a landscaped front yard and a wooded backyard. I spent hours jumping from stone to stone in my mother’s rock garden, picking blueberries from bushes in our front yard before the birds gobbled them up, and ‘designing’ and planting the annual bed along the walkway to our front door. When I was 7 or 8 years old, my best friend and I were allowed to explore the woods by ourselves. One time we ‘discovered’ a plant we called the umbrella plant. It was about 5 inches tall with horizontally held, fan-like branches covered in scale-like leaves. We excitedly brought it home and, although it didn’t last long, the impression did.

“Preschool educators have long known that animals, plants, water, and other aspects of the natural world delight children and draw them in as learners.”—Natural Start Alliance

This exposure to nature and being allowed to explore outside on my own shaped many aspects of my life, including my decisions to study plant science at Cornell University and earn a master’s degree in elementary education at Loyola University, Chicago. My position as family programs coordinator at the Chicago Botanic Garden combines my fondness for the natural world and my love of children and teaching. I look forward to teaching and sharing similar experiences with children at the new Regenstein Learning Campus.”

“Here I am in my teens at a Chicago River cleanup in the woods, holding a toad. I was lucky enough to have attended a Chicago public high school that got me out in the forest preserves and into nature. The experiences are part of why I studied ecology, and also why I wanted to inspire other Chicago teens to do the same. Now, I recruit Chicago public high school students for Science First and College First.”

“My best childhood memories were all outdoors…playing in the garden, growing vegetables, picking up seashells, going bird-watching. That love of nature has stayed with me, and I consider myself very fortunate to be able to have a career that allows me to continue to explore and study plants and the natural world.”

“There are very few pictures of me as a child, most of them posed…except this one. It is outside in an open field, where I and my siblings tramped around at will, falling in love with the outdoors.”

“I grew up in a small town in Nebraska in the corn belt where, as you can imagine, trees were not very common. I spent a lot of quality time either climbing in or sitting under this particular tree when I was young. A few years after this photo was taken, a family of owls took up residence in it. I can’t imagine a childhood that didn’t involve nature play—climbing trees or sitting quietly with binoculars to watch owls interact with each other and the plants that they called home helped me see the world from a larger vantage point, and made me want to understand it by becoming a scientist.”

“Growing up in a part of Australia where the weather was often nice, it was easy to spend most of your time outside. I am not sure I can remember when I was not outside in flip-flops and board shorts. No matter what we were doing, there was always something to get me excited. Sometimes it was something as amazing as a dolphin swimming close to the beach or a kangaroo caught by surprise on our hikes. It was clear from a young age that the thing that got me so excited was the flora, and a botanist was born. The smell of the eucalyptus still sends memories flooding of hikes after rains, recalling the wonderful discovery of small patches of donkey orchids in winter.

Ultimately, I combined this love of native flora with working in the garden. I would often spend afternoons walking through the Adelaide Botanic Garden for inspiration and to marvel at its collections. I went to university to study horticultural sciences and volunteered on weekends at the botanic gardens as an undergraduate. All of these interactions played an obvious role in my life’s trajectory as a scientist at the Chicago Botanic Garden.”

“My mother was a teacher and felt that it was so important to incorporate learning play. Here’s what she had to say: ‘Lisa, there was probably no time in your early years that you were not connected to nature. Starting with the simple joy of playing outdoors, you watered flowers for grandma and dad, made daisy chains, raked and played in the leaves, built snowmen, ice skated, and sculpted sand castles at Lake Harriet, Minneapolis. You planted gardens, learned to fish at Deer Lake. You loved having collections of rocks and leaves (author’s note: yes, I majored in geology and my childhood rock collections are still in the basement). You showed a love of dogs, gerbils, fish, white mice, even squirrels (you fed them peanut butter crackers at the back door). You were bonded to nature as a young child and it continues to this day!’”

“In my early childhood, I remember playing at my friend’s house. They had a very old forsythia bush, perfect for ‘house building,’ great tunnels, and hours of imaginative fun! When we were a bit older, the same best friend and I would meet down by the creek (between our two houses about a mile from each of us). We would spend hours walking in the creek bed, looking for crayfish, spiders, plants. (We brought skunkweed home to harass our siblings.) We would build forts with branches and grasses. When I was 12 years old, on a family vacation, we went to an enormous conservatory at the Grand Ole Opry Hotel. I walked into a breathtaking environment, and I knew. I knew I wanted to make people feel that same rush, excitement, wonder, as I did, and I was going to do it with plants. The rest, as they say, is history.”

“This picture (left) was the first time I had flowers of my own, and it was so exciting! Even to this day I still try to make sure I have at least one zinnia plant somewhere in my life, whether it’s in a garden I work in at the Chicago Botanic Garden or at home because I fell so in love with the flowers as a child.”

Painting with Veggies

Youth Education - Fri, 03/25/2016 - 11:08am

We’ve discovered a fun way to encourage our Camp CBG campers to try a salad. Many kids turn up their noses when they hear the word, but after painting with food, our campers are eager to “dig into” their creation.

For little ones, this project is easy and fun to do with a grown-up and provides opportunities to identify colors and start learning about plant parts. Older kids can use new kitchen tools (with adult supervision) and discuss what is really a fruit or a vegetable

Watch Painting with Veggies on YouTube.

Supply list:
Cutting board
Sharp knife
Food processor or grater
White plates

Recipe:
1 red bell pepper (see notes)
2 carrots
¾ cup chopped pineapple
½ head red cabbage
1 head broccoli (see notes)
Favorite salad dressing—we used ranch

Notes from the chef/artists:

  • Bell peppers don’t work well in the food processor. I recommend finely chopping them with a good knife. 
  • Broccoli was a bit difficult to work with. Next time I’d use a bag of broccoli slaw.
  • Other vegetables I’d like to try are fresh corn (off the cob), chopped celery, black beans, and dried fruits or nuts.
  • This would be fun to do with a spiralizer, which would add a different texture. Check out this post by fourth-grade teacher Lindsay for eight great spiralizer ideas.

Prepare veggies by shredding in a food processor, and place each kind in a bowl. Use your imagination to “paint” your canvas (plate). Make sure to take a picture before digging in. Once you are done creating, top with dressing and enjoy.
