Help track blooms now for Project BudBurst

Plant Science and Conservation - Sat, 03/04/2017 - 8:48am

In the Chicago region, we have been having record-breaking warm weather: For the first time in 146 years, the National Weather Service documented no measurable snowfall in either January or February. Chicago’s record year is mirrored globally. Scientists from both NASA and NOAA recently released reports showing that 2016 was the hottest year since global temperature tracking began in 1880. If that sounds familiar, it is: It was the third record-breaking warm year in a row. And so far, the warmth is continuing in 2017.

“Is it hot outside?”

Many of us in the United States are experiencing unseasonably warm winters with leaf and flower buds bursting weeks earlier than normal. While these balmy days may be welcomed by those in northern climes (ourselves included!), they may cause problems later in the year, for both natural and agricultural systems. 

In natural areas, we might experience more phenological mismatches. These occur when species that depend on each other do not respond to climate cues in the same way. For instance, hummingbirds and butterflies that overwinter in the tropics and migrate north as the days get longer may arrive to find the plants they depend on for nectar have already finished blooming.

In agricultural systems, fruit production could be harmed in a couple of ways. First, if winters are too short, chilling requirements for flower bud formation may not be met in southern regions (say, for Georgia peaches). In more northern areas, early blooms coaxed out by unseasonable warmth could be killed by a late frost (say, for Michigan cherries). In short: A mild winter and early spring may not be as “peachy” as one might hope.

This is where you come in.

Scientists at the Chicago Botanic Garden and across the country are researching the impacts of these warmer winters on plants and ecosystems, and one challenge in this work is the need for very large, long-term data sets documenting when plants leaf out and bloom. We need your help.

The Chicago Botanic Garden has recently taken over Project BudBurst, a national citizen science project designed so you can help us collect just such data, and in this very warm year, it is more important than ever that we collect as much data as possible.

Three of the most common plants in our area—and earliest to bloom and leaf—are forsythia (Forsythia × intermedia), red maple (Acer rubrum), and Virginia bluebells (Mertensia virginica). When you see that first yellow forsythia bloom, the first leaf on your red maple, or that first bluebell bud open, let us know by contributing to Project BudBurst. It’s easy.

Visit Project BudBurst
and create an account
and you’re ready to go.

Once you’ve created an account, you can make a single observation on any of our target species.

If you want to make more of a commitment, you can create a site location—your backyard, for example—that will allow you make observations on the same plants throughout the growing season, from budburst to leaf fall.

Your phenology observations—especially in unusual years like this one—can help scientists understand how plants are likely to respond to future climates. And that will help us all adapt to the changes that will come!

Pantone Color of the Year: ‘Greenery’ and Its Many Benefits

Garden Blog - Thu, 03/02/2017 - 9:18am

The 2017 Pantone color of the year has us doing somersaults at the Chicago Botanic Garden. Pantone’s “greenery” has inspired us to discuss the importance of green space and nature’s role in our well-being.

Every year, Pantone selects a color of the year. This year’s color selection, “greenery”—a revitalizing shade “symbolic of new beginnings”—inspired us to discuss the benefits of spending time in nature with our Horticultural Therapy participants—a conversation worth sharing with the entire Garden community.

 Eucalyptus Sensory Mobile.

January’s Gardening for Life Enrichment project: Eucalyptus Sensory Mobile.

The color “greenery” brings many images to mind: lush forests, fruits and vegetables, fields of grass, and wild jungles. Being in spaces of green, or viewing them from inside, brings about psychological and physiological changes in our bodies. It slows our breathing, reduces stress, and encourages us to take in what is around us. 

Why does “greenery” impact us the way it does? There are countless reasons why we feel calm, restored, and connected while in nature. Largely, it is because we are connected to it as human beings. The Biophilia theory, formulated by evolutionary biologist E.O. Wilson, teaches us that because our survival has been linked with nature (water, shelter, food), our love of it is built into our DNA. 

Being in green space allows us to rest our minds. More specifically, it allows our directed attention a chance to restore. Directed attention is what we use to concentrate on the day-to-day tasks—sending emails, conducting meetings, taking exams, etc. Our directed attention can quickly become fatigued when it is overworked. This is where nature comes to the rescue.

According to researchers Rachel and Steven Kaplan, nature provides us with elements of “soft fascination,” such as watching tall grasses in the wind or listening to a babbling brook. These elements engage our involuntary attention—attention that is reactive to stimuli and doesn’t take cognitive effort—and when our involuntary attention is engaged, our directed attention gets to take a break. Creating opportunities to take breaks in green space has been statistically proven to increase concentration and alertness, happiness, and connectivity—no matter one’s age, ability, or background. As we like to say, nature (or “greenery”) is one of the best vitamins you can take to keep up with the hustle and bustle of life. 

Watching butterflies is one of the many ways nature provides us with "soft fascination."

Watching butterflies is one of the many ways nature provides us with “soft fascination.”

Theories and studies, such as the ones listed above, have inspired a resurgence in restorative landscapes. This resurgence has led to outcomes such as the following: greater number of gardens in healthcare facilities; nature-based curriculums and education centers (e.g., the Nature Preschool at the Garden); and professional development opportunities such as the Healthcare and Therapeutic Design Professional Practice Network in the American Society of Landscape Architects, and the Chicago Botanic Garden’s Healthcare Garden Design Certificate Program.

There are many elements one could incorporate when creating a therapeutic green space. When we design a garden with therapeutic intentions, we include some of the following features:

  1. A 7:3 vegetation vs. hardscape ratio (70 percent vegetation; 30 percent hardscape)
  2. Opportunities to engage with nature, such as raised beds/vertical plantings with high sensory plant material
  3. Elements of soft fascination (e.g., water features, tall grasses, bird feeders, butterfly gardens)
  4. Accessible and comfortable garden elements (e.g., smooth surfaces, ample shade, and seating areas)

Most importantly, we design spaces that create a positive distraction to the everyday experience. It is important that spaces of “greenery” evoke joy and excitement, engaging visitors in the space with or without planned activities.

Visiting a green space, even viewing one from inside your home or office, brings about positive and impactful changes in our bodies and minds. It is one of the most universally accessible and free healthcare resources in our modern world. At the Chicago Botanic Garden, we cultivate the power of plants to sustain and enrich life. We believe strongly in the power of “greenery” and its impact on our health and well-being. Through thoughtful display gardens, designs, programs, and research, we continue to educate the public and inspire future generations to become stewards of the environment. After all, a little “greenery” goes a long way.

Orchidpalooza: Rare orchids in print in the Lenhardt Library

Garden Blog - Wed, 02/22/2017 - 9:15am

Each year’s Orchid Show at the Chicago Botanic Garden features something new and dynamic—and each year, the Lenhardt Library’s Orchid Show exhibition showcases something rare and dynamic.

Free Talk on Sunday, February 26, at 2 p.m.

This year’s exhibition, Orchidpalooza: Illustrated Orchid Varieties, features five unsigned, untitled, and unnumbered artist proofs that are attributed to English landscape artist Henry Moon (1857-1905). The proofs were most likely intended for a third series of a collection called Reichenbachia: Orchids Illustrated and Described, commissioned by Frederick Sander (1847-1920).  Moon was Sander’s son-in-law and was responsible for the 192 chromolithographs published in the monumental two-volume work. This work is considered Sander’s homage to Heinrich Gustav Reichenbach (1824-90), the “Orchid King” who succeeded John Lindley (1799-1865), the “Father of Orchidology,” as the leading orchid authority of the late 1800s.

The Warm Weather and Your Garden

Garden Blog - Tue, 02/21/2017 - 1:17pm

The late February weather in Chicago has been a glorious time to be outside and work in the garden. But the unseasonably warm weather has also raised questions about the long-term effect on plants and what garden tasks are appropriate.

It is best to hold off on doing any detailed clean up of garden beds as the mulch and leaves in the beds will provide some protection to any early growing perennials when the weather eventually turns cold again. Raking leaves off the lawn and cutting back perennials are all fine to do now providing your garden soil is not too wet.

Snowdrops are blooming at the Garden.

Early flowering bulbs like snowdrops that are in flower here at the Chicago Botanic Garden are very tolerant of the cold. Daffodil and tulip foliage is coming up; these might end up being damaged by a spell of cold weather, but this should not affect the spring flowers. You do not need to take any special maintenance steps to protect these plants.

If you have some perennials that are growing in a warm area of the garden with more pronounced growth, they might benefit from a light layer of mulch. For the most part, though, there is nothing special for most gardeners to do in their perennial beds.

This is great weather to prune but proceed with care. Spring flowering shrubs like viburnums, lilacs, and forsythia set their flower buds last year so pruning done at this time of year will remove flower buds and reduce the number of spring flowers. You can still prune—just be aware of the flower buds as you are pruning. Forsythia flowers along the stems while viburnums will have a flower bud at the ends of the stem.

The dormant season, and in particular late winter, is the best time of year to complete rejuvenation pruning, which is the aggressive pruning of overgrown shrubs to bring them back into scale with the garden. Shrubs like hydrangea (except oak leaf hydrangea), potentilla, and spirea that flower on new wood respond well to pruning now too. For instance, I cut my Annabelle hydrangea back to the ground each spring.

Any plants installed last summer or fall should have been mulched when they were planted. If they were not, then mulch them now to help mitigate the temperature swings in the soil and prevent frost heaving of any plants in spring. The freezing and thawing of the soil can push recently installed small plants such as 1-gallon perennials or ground covers that were grown in containers out of the soil as the weather transitions to spring.

If we receive a good covering of snow, the snow itself will not harm plants unless it builds up on them and breaks branches. It is a good idea to brush plants off during a storm if you observe them getting weighted down. Later snowstorms are more likely to come in wet and heavy. Leave the plants alone if the snow has frozen on them to avoid breaking branches during the removal process.

Enjoy the warm weather and the early blooms, both at the Chicago Botanic Garden and in your own backyard.

Demystifying Seed Catalogs

Garden Blog - Thu, 02/16/2017 - 9:23am

The arrival of seed catalogs in mailboxes ranks as one of the most hopeful times in a gardener’s year, as it provides us with a welcome link to spring.

February is the perfect time to plan next spring’s vegetable garden. One of the first considerations is deciding what to grow. This can be answered by simply listing the veggies or asking your family to name the veggies they like to eat. There are a few other considerations before placing your order for next year’s garden—such as deciding if you should plant seeds or transplant vegetable starts. Seeds of many vegetables can be sown directly in the garden, including root vegetables like carrots, radish, and beets. Peas, beans, and squash are also best directly sown. Cabbage, tomatoes, and peppers are better given a head start inside first, and then transplanted into the garden as small plants, because they need a long, warm growing season.

Brassica oleracea 'Blue Wind' broccoli

For spring plantings, set broccoli transplants out two to three weeks before the last spring frost date.

 Planter potted up with edible greens.

Edible spring planters can be harvested and repotted with next season’s veg.

Timing is important in the vegetable garden, and knowing that our growing season has approximately 170 frost-free days helps guide decisions on which plants to plant and when to plant. Our risk of frost is generally from October 15 through April 27, but can vary two weeks in either direction. Understanding that vegetable varieties have varying tolerances to frost helps you plan your planting calendar. For example, those very hardy plants like collards, kohlrabi, kale, spring onions, pea, spinach, turnip, and cabbage can be planted out four to six weeks before our last frost date. Those called “half hardy” or “frost tolerant”—such as beets, Swiss chard, carrots, cauliflower, and mustard—must be planted a bit later; two to three weeks before the last frost date.

The best seed catalogs will help decipher a gardener’s questions, and help plot, measure, and sort out the seed math needed to get started on a vegetable garden. Most seed is available in organic and non-organic options, with the latter usually the least expensive. Good catalogs provide keys to help decipher the icons (vegetable resistance codes) in plant descriptions. After all, a seed company’s success is based on a gardener’s success with their products.

As our nutritional consciousness rises, the taste and the health benefits of growing your own organic produce is a pursuit worthy of winter afternoons spent planning.  

Here are a few of my favorite seed companies:
(Consider going paperless; all of these catalogs are available online.)

Johnny’s Selected Seed
www.Johnnyseeds.com (877) 564-6697

Johnny’s Selected Seed is a 43-year-old, employee-owned company in Maine, recognizing that “good food is the basis of our well-being.” Widely used by home gardeners and small market farmers, the seed selection includes hundreds of vegetable, flower, and herb varieties in organic and non-organic (options) seeds. The catalog provides grower’s information for the novice to advanced gardener—it’s a virtual garden education. Johnny’s provides well-tested tools for garden tasks from bed prep to trellising, to season extension, and cover cropping. Comparison charts like the one on leaf lettuce help gardeners select seeds based on their specific growing conditions. Charts and photos compare length, width of mature veggies, and harvest windows.

High Mowing seed catalogHigh Mowing Organic Seeds
www.highmowingseeds.com (866) 735-4454

High Mowing Organic Seeds simply provides 100 percent certified organic, non-GMO Project Verified vegetable and flower seed to organic growers. The helpful seed catalog key on page two of the new 2017 catalog includes a tutorial on how to read the individual variety descriptions that follow. Seed definitions of open pollinated (OP), heirloom, and hybrid seeds are aptly explained and marked throughout. Crop types are headed by general cultural information or the “how to” grow beans for example. Then each listing is complete with the days to maturity (based on conditions in Vermont where HMO is located), disease resistance and any special attributes of the plant including breeder credit. Don’t miss the invaluable planting chart on the last page. High Mowing Organic Seeds is an excellent resource for passionate organic growers.

The Cook’s Garden
www.cooksgarden.com (800) 457-9703

Burpee acquired The Cook’s Garden more than ten years ago, and it has helped nurture America’s love affair with healthy, delicious food by offering the best gourmet veggies, greens, and herbs from around the world. The catalog offers seeds and plants for gourmet gardeners, with vegetables and fruits often pictured in recipes alongside culinary tips. Offering well-curated collections of helpful horticultural gadgets, you’ll find ash-handled tools, trellising supplies, rain gauges, and garden hods (flat, wood-handled basket) to make harvesting a snap. The Cook’s Garden catalog offers a wide range of quality products to indulge your inner gardener-chef when produce arrives in the kitchen. They’ve got canning, preserving, and dehydrating supplies covered. If the ultimate luxury is having the right tool for the job, check out the herb snips, the strawberry huller, and my current obsession, the new pickle slicer.

Seed Savers Exchange
www.seedsavers.org (563) 382-5990

Seed Savers Exchange helped start the heirloom seed movement by locating and preserving almost 20,000 varieties by growing them and seed banking at Heritage Farm in Decorah, Iowa. The not-for-profit’s mission is to conserve and protect America’s culturally diverse but endangered food crop heritage for future generations by collecting, growing, and sharing open pollinated seeds and plants. The catalog contains an anthology of stories and fascinating anecdotes connecting the reader to plant history, and has a comprehensive roster of vegetable seed many of which are certified organic. Be sure to check out the heirloom flower seed, garlic, and seed potatoes. It’s a great resource for seed saving supplies and helpful guides to get started planting and seed saving.

Pinetree Garden Seeds catalogPinetree Garden Seeds and Accessories
www.superseeds.com (207) 926-3400

Pinetree has been a year-round source for the home gardener for more than three decades. Their product lines go well beyond a fairly complete line of gardening gear, including soil kits and amendments, and animal deterrents. Also offered are natural bath and hair products, kitchen gadgets (I want the tortilla press), and bee, bat, and bird products. If you’d like fragrant oils and herbal teas to go along with your vegetable seeds, look no further than Pinetree. There is a comprehensive compendium of some of the best gardening books that I’ve seen.

Baker Creek Heirloom Seeds
www.rareseed.com Fax: (417) 924-8887

Baker Creek offers 1,800 vegetable, flower and herb varieties claimed to be the largest in our country.  A focus on preservation, it not surprising they have one of the largest selections of seeds from the nineteenth century. The fittingly named Rare Seed Catalog is like the Vogue magazine of the vegetable world. It wins the prize for the most beautiful photographs of the most avant-garde produce collection, complete with nutritional factoids and culinary inspiration. Stories from seed collecting expeditions around the world—recently Thailand, Myanmar, and India—are in the Heirloom Gardener, an associated and nationally distributed magazine written as a tool to not only promote and preserve our rich agricultural history but as explanation of why we need to care about it. The Rare Seed Catalog provides a selection of 78 varieties of melon and 20 types of okra. Baker Creek has a limited but diverse availability of live plants to ship. If goji berries, ginger root, and dragon fruit tickle your fancy (and you either live in the subtropics or have a greenhouse available) look no further, they’re in the Rare Seed Catalog. Baker Creek encourages political activism, and the catalog is written with an underlying ripple that we’re reaching the tipping point in the struggle against GMOs.

Specialty catalogs

Vermont Bean Seed Company

Varieties/cultivars and tips for direct seeding into spring gardens

It’s hard to resist a list of a few of my favorite varieties to directly sow into the spring garden. Knowing how much seed will sow a 10-foot row and the days to maturity (when the harvest can be expected) is the type of garden math that tangles up many a gardener, but quality catalogs will provide vegetable grower’s guides to help to sort out how much seed you’ll need. 

Radish: Direct-sow spring radish as soon as the ground can be worked, or four to six weeks before the last frost. Radish is best grown quickly in cool, damp conditions. It’s easy to grow, and requires only 28 days from planting to harvest. Try these spring radish cultivars: ‘Early Scarlet Globe’, ‘Rudolf’, and ‘Crunchy Royale’.

 Beets.Beets: Nothing says spring like tender, freshly harvested baby beets. Sow about two weeks before our last frost date and thin to 3 inches between seedlings. Fertilize with liquid seaweed. Beets have great culinary versatility, so plant a combination of gold and red. ‘Detroit Dark Red’, ‘Bull’s Blood’, and ‘Burpee’s Golden’ are great choices.

Swiss chard: We love ‘Rhubarb’ and ‘Five colored Silverbeet’. These greens can grow through the entire gardening season. By harvesting just the outer leaves with a harvest knife, the plant stays in place and the integrity of your design stays intact.

 Carrots.Carrots: The sweetest, juiciest, and most flavorful carrots are the French heirlooms. Sow two weeks before the last frost date. Carrot is slow to germinate, so have patience. Our favorite varieties for Chicago growers: ‘St. Valery’, ‘Paris Market’, and ‘Scarlet Nantes’.

Spinach: One of the earliest-germinating cool season vegetables, spinach can be direct sown in 2-inch bands or rows four to six weeks before the last frost. Plant ‘Corvair’, ‘Tyee’, or ‘Donkey’ for the most reliable spring crops.

Lettuce: We love ‘Tennis Ball’, ‘Black Seeded Simpson’, ‘Rouge d ’Hiver’, and ‘Winter Density’. One gram of seed will sow a 15-foot row.

Spring greens: Try mache, arugula, or mizuna; 30 to 50 seeds will seed one foot of row when sown as a cut-and-come-again salad mix.

Designing the 2017 Orchid Show

Garden Blog - Thu, 02/09/2017 - 4:43pm

Take a sneak peek behind-the-scenes at the Orchid Show, the Chicago Botanic Garden’s biggest flower show of the year. Buy tickets here.

 Phalaenopsis Sogo Yukidan 'V3'

Phalaenopsis Sogo Yukidian ‘V3’

We’ve rolled out the tall ladders, prepped hanging baskets with Spanish moss, and worked hard to keep 10,000 warmth-loving tropical orchids happy (including an orchid that is rarely shown in the United States, Phalaenopsis Sogo Yukidian ‘V3’; be sure to check out the unusual number of big blooms on each spike).

It’s all hands on deck for the Show, which runs February 11 to March 26, following the Members’ Preview night on Friday, February 10. Volunteers across the Garden and beyond have pitched in to help from departments including Education, Model Railroad, and Horticultural Therapy Services, along with our Woman’s Board.

Volunteers from all departments unpack orchids for the Orchid Show 2017.

Volunteers from different departments unpack orchids for the Orchid Show 2017.

It all starts with ideas from our creative team, which starts brainstorming shortly after the end of the previous year’s Orchid Show. 

 Sketch of the Orchid Show designs for 2017.

Last June, horticulturist Brian Barker had an idea that looked like this.

The Orchid Show displays in the Tropical Greenhouse.

Now it looks like this: an arch of Vanda and Oncidium orchids between the palms.

Setting up the framework

In the completed archway, supporting vines are woven together and attached to a hidden framework. Notice the dangling aerial roots from orchids that are epiphytes—plants that grow on trees, with above-ground rather than in-ground roots.

Sometimes, things don’t always go as planned. Work on the 13-foot high orchid “wind chime” got delayed while we waited and waited for a delivery of bamboo supports from Colombia… Luckily, the shipment arrived before the Show.

When you walk into Nichols Hall, don’t forget to look for the dozens of blooms overhead.

The finished orchid "wind chime" in Nichols Hall

The finished “chime” looks deceptively simple…

This year’s theme is Orchids in Vogue, a playful look at the influence of orchids in popular culture, including fashion. Last summer, senior horticulturist Salina Wunderle came up with an idea for an orchid “dress.” Now we have three design teams working on orchid dresses; come see the final result.

 3 orchid gowns.

This materials sketch by horticulturist Salina Wunderle details one of this year’s highlights: orchid “dresses.”

Salina Wunderle's dress sketch shows how her material choices will be layered to create the final look.

Under construction, this is one of 3 gowns made of orchids and other plants to be displayed at The Orchid Show this year.

We did some trial runs, testing materials to help determine weight and structure, and making sure they’ll stay fresh for the run of the Show.

Studying Fungi Amid the Ghost Orchids

Plant Science and Conservation - Tue, 01/24/2017 - 10:05am

Just like magic, a ghost orchid (Dendrophylax lindenii) appears overhead in a Florida swamp. Its pale roots extend like gloved fingers across the bark of a pond apple tree (Annona glabra), while its graceful flower reflects onto the shadowed water below.

Doctoral student Lynnaun Johnson wades over for a closer look. Habitat is shrinking for this reclusive orchid, and he is using a unique approach to better understand the species’ uncommon lifestyle.

During March 2016 fieldwork in the Florida Panther National Wildlife Refuge, Johnson went deeper every day—even when it meant paddling his canoe within 10 feet of a sunstruck alligator to reach the widely dispersed plants. Each time he located an orchid, he looked past the plant and took a sample from the bark of its host tree.

“What I’m interested in primarily is identifying the fungi within the habitat of these particular orchids,” said Johnson. “If you are going to place a ghost orchid out in nature and it can’t acquire nutrients or it doesn’t form the right associations with mycorrhizal fungi, it’s not going to survive,” he explained. “If these trees have a particular suite of fungi, that might be something that we need to consider in terms of a healthy population.”

Species within the orchid family are generally known to depend on fungi to help them through key stages of life, such as growing from a seed into a seedling. But there are differences in how those partnerships work. When an orchid lives in soil, the fungi help move water and nutrients to and from the roots. But when the orchid lives on a tree, scientists are less certain of what occurs.

Until recently, they believed that orchids growing on trees were less likely to depend on fungi long term. This belief was encouraged by the discovery that the prominent roots of plants like the ghost orchid actually conduct photosynthesis—a process in which sunlight becomes sugar. That process is managed by leaves in many other orchid species. If the roots are so full of nutrients, do they really need any help from fungi?

They sure do, said Johnson and his collaborators, who examined the roots of another tree-bound orchid species, the vanilla orchid (Vanilla planifolia). Using modern technology called high-throughput sequencing that can produce more detailed results than ever before, they found that epiphytic orchids—those that grow on trees—also rely on fungi to carry out essential functions. “We know the importance of photosynthesis, but that doesn’t mean if a plant is photosynthesizing it’s healthy. It means it will continue to rely on fungi to grow and develop,” said Johnson. He recently documented the presence of fungi in the roots of ghost orchid root samples from his field work.

Back in the field, Johnson wondered if the type of fungi present on certain tree species is what led the ghost orchids to select them as their home over other trees. In the Florida refuge, the orchids are found only on pond apple and pop ash trees (Fraxinus caroliniana). So during his fieldwork, he sampled both types of trees, some with and some without orchids. As a point of comparison, he also sampled the bark of bald cypress trees (Taxodium distichum). He plans to conduct more fieldwork this spring before examining the bark for fungi.

The number of ghost orchids in Florida has dwindled as more and more swamps have been drained to build new housing complexes to accommodate a growing population. There have also been times when the trees in the swamps were logged.

Johnson will later examine the roots of other orchid species that neighbor the ghost orchids on trees. This will further clarify the importance of fungi to the ghost orchid, which he suspects relies on the fungi more than neighboring orchid species. He also has his eye on a population of orchids growing naturally in Cuba on a larger number of trees that he hopes to study as well.

Johnson aims to help people understand that there is more than a one-to-one relationship in nature, and that multiple partnerships contribute to the health of each species and system. For example, “if we understand the significance of host trees, then we can preserve both the host trees and epiphytic orchids at the same time,” he said.

Orchids may become a lifelong pursuit for Johnson, who moved to Illinois from his childhood home on the island of St. Lucia to pursue his studies. He hopes to specialize in the study of fungi as it relates to plants and the conservation of wild lands and waters.

Autumnal Leaves on Loan to Philadelphia

Lenhardt Library Blog Posts - Thu, 01/05/2017 - 9:14am

One of my favorite volumes in the Lenhardt Library’s rare book collection (although I love them all) is Autumnal Leaves by Ellen Robbins, published in 1868. Each of the 18 original watercolor paintings of autumn leaves looks so true-to-life that you want to reach out and pick a leaf off the page.

This volume, specifically, the sumac watercolor, will be on display at the Philadelphia Museum of Art, in the American Watercolor in the Age of Homer and Sargent exhibition which runs March 1 to May 14, 2017. I’m delighted that an East Coast audience will have the opportunity to share this treasure.

Although we’ll miss the book while it’s away, through the Lenhardt Library’s digitization program, each page of the book is viewable in the Illinois Digital Archives repository.

You’ll find the sumac shown here on page 4 of the content list. View the full collection of prints here: http://www.idaillinois.org/cdm/compoundobject/collection/ncbglib01/id/3364/rec/2

Additionally, the sumac will be published in the American Watercolor in the Age of Homer and Sargent exhibition catalog.

A unique, one-of-a-kind book, this is the only copy listed with holdings in a library.

Bound with gold tooling and gilt edges, the volume is quite brittle and fragile. It has just been conserved by a professional book conservator to prepare it for exhibition.
