The Link Between Plants and Animals

How do you bring an endangered plant species back from the brink of extinction? The answer might be found in zoo animals.

That’s the inspiration for Chicago Botanic Garden scientist Jeremie Fant’s latest research. Fant, a molecular ecologist and plant genetics guru, is working with other botanic gardens around the world to develop conservation and reintroduction plans modeled after the ones used by zoos to protect endangered animal species.

Is it Spring or Winter? Flowers Wage Their Bets

As if on cue, tiny green leaves peek out from the dark soil each spring, reaching for the sun.

But how do flowers know it’s spring? And can they detect real spring versus a warm spell when it’s still winter?

Invasive Species: Understanding the Impact, Repairing the Damage

What do a pharmacist named Eugene, a cargo ship, and a home garden have in common? They all helped introduce invasive species that affect the Chicago area today.

Although invasive species are almost always new to an area, it’s not a plant or animal’s origin that makes them invasive—it’s their impact. Invasive species spread widely as they out-compete local native species for resources like food, water, light, and space, and can eventually damage entire landscapes.

Community—and gelato—help undergrad scientists thrive

Angelica Ostiguin

College student Jessica Tillery came to the Chicago Botanic Garden for the summer to work in a plant science lab, hoping to jump start her career in habitat restoration—which she did. And she got the chance to develop something she wasn’t necessarily expecting: a community of scientists, from high schoolers to Ph.D.s, who taught her, supported her, and became her friends. And those relationships, Tillery said, “made her experience.”

Why we need green spaces

Hummingbird Gardening

Wildlife and plants are constantly on the move. Birds, deer, and even water animals cross trails, roads, and waterways to seek food or habitats that are necessary for their survival, and the seeds of plants can travel by wind or other means to establish in new green spaces.

...and this year's fall colors

It’s hard to think of fall without picturing a mosaic of trees with warm-colored hues. Amber browns, golden yellows, and blazing reds cover many natural areas in the Midwest, including the Chicago Botanic Garden. It’s all thanks to fall’s shorter days and cool nights.

But with our changing climate, what happens to that classic fall color we’ve come to know and love?

This Amazing Plant Changes Gender from Year to Year

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 also bloomed at the Garden.

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

Got milkweed? Let’s apply some science

If you have heard about milkweed, you no doubt know about the plant’s unique relationship with the Monarch butterfly (Danaus plexippus). Milkweeds are the only plants on which monarchs lay their eggs, and its caterpillars, also called larvae, eat milkweed leaves to grow. But these plants have other interesting characteristics, including blooms that are amazingly complex.

Alice the Amorphophallus—An Update on Titan Arum Fruit

Thousands of visitors to the Orchid Show at the Chicago Botanic Garden have been delighted to see a special guest star at the Tropical Greenhouse: Alice the Amorphophallus is on display, in full and glorious fruit! 

Visitors are asking: why are some of the berries on the titan arum (or corpse flower) skinny and small, while others are big and plump?

Dr. Pat Herendeen and “Titan Tim” Pollak plucked a few of each in mid-February, X-rayed them, and performed a bit of berry surgery to get the answer.

Another Reason to Battle Buckthorn

As plant enthusiasts, we often focus on how plants are affected by their environments. Their growth is affected by weather, water, nutrients, etc. But the plant-environment relationship is a two-way street, and plants can have a strong influence on the habitats they live in. We might experience this by walking in a forest and feeling ground beneath our feet that is spongy from the buildup of slowly decaying leaves that accumulated over decades or centuries.

Splendor in the Tallgrass

When my mother first moved from England to Chicago in the late 1950s, she’d never heard of a prairie. In England, a grassland is called a meadow. But every kid in the neighborhood near Chicago’s Midway Airport called the empty, overgrown lots between buildings, and the grassy areas in the giant railroad yard, “the prairie.”

Make Way for Monarchs

Did you know that one in every three bites of food you take required a pollinator visit? Pollination is essential for many of our favorite foods—from almonds to vanilla, and so many fruits and vegetables in between.

The decline of pollinators around the world is threatening not only our food supply but also the function of plant communities and ecosystems. Multiple factors play a role in pollinator decline, including land-use changes, pesticide use, climate change, and the spread of invasive species and diseases.

Seeking out the Elusive Wild Phlox

Recently, I had the pleasure of speaking at a symposium on plant exploration that was held in Des Moines, Iowa. The audience was enthralled following the plant-collecting exploits of such luminaries as Dan Hinkley, one of the founders of the renowned (alas, no more) Heronswood Nursery, to far-flung locales such as Vietnam, China, and Bhutan.

Much of my presentation focused on plant collecting a tad closer to home—not as exotic perhaps, but still crucial in support of my research as the Chicago Botanic Garden’s plant breeder. So let’s go seek out the elusive wild phlox.

The Goldenseal Dilemma

In late October 2012 when I was driving down a country road in rural northwest Illinois, I spotted some bright sky-blue asters blooming near the corner of a woodlot. I was traveling between nature preserves in this area of the state collecting seeds for the Dixon National Tallgrass Prairie Seed Bank, so my mind was already tuned in for interesting native flora that might produce a collection for the seed bank. It was impossible to make a positive I.D.

Capturing the Value of Wild Plants

Maps had been followed, clues tracked, and early this summer the fortune was found.

Standing on the far side of a hummock swamp in Delhaas Woods in Bristol, Pennsylvania, Andrew Bunting had located a unique magnolia tree population on the edge of fading away. He had discovered the treasure he set out to find. Often, this is where the story ends. But when the prize is an elusive plant sought by scientists nationwide, this is where the story begins.

Summer Bloom Highlight: The Prairie Rose

Pondering the Prairie Series

Rosa setigera, or Illinois rose, grows in moist prairies and thickets, and is a typical wild rose in many ways: five pink petals, with lots of yellow stamens in the center supported by prickly stems. There are distinct differences, however. Illinois rose is larger than most wild roses of the prairies—often growing up to 8 feet tall, while others rarely grow more than 4 feet tall and usually less.

Working to restore a rainbow of wildflowers in the Colorado Plateau

I’m a conservation scientist here at the Chicago Botanic Garden. I have an incredible job that allows me to work with many wonderful graduate students and a team of researchers to study ways to restore natural areas in the Colorado Plateau.

If you’ve ever visited national parks like the Grand Canyon or Arches, you’ve experienced at least some of what the Colorado Plateau (also known as the Four Corners region) has to offer. It includes more than 80 million acres across Utah, Colorado, New Mexico, and Arizona—and the largest concentration of national parks in the country.

Spike’s Teachable Moment

What an amazing plant science moment occurred in the Semitropical Greenhouse this morning, as a fascinated crowd gathered to see what was happening with Spike, the titan arum.

On Saturday, it was determined that Spike had run out of the energy it needed to continue its bloom cycle. Spike is powered by energy from the sun, stored in its beach-ball-sized corm—a tuber-like underground structure. A tremendous amount of energy goes into producing the single, giant flower structure that a titan can send up in its first decade or so of life (Spike is about 12 years old).

How Love and Science May Defend a Wild Orchid

Life on the prairie hasn’t been a breeze for the beautiful eastern prairie fringed orchid (Platanthera leucophaea).

Once common across the Midwest and Canada, the enchanting wildflower caught the attention of collectors and was overharvested throughout the 1900s. At the same time, large portions of its wet prairie, sedge meadow, and wetland habitat were converted to agriculture. By 1989, just 20 percent of the original population of Platanthera leucophaea remained, and the orchid was added to the federally threatened species list.

The Evolution of a Research Idea

Five years ago this past May, I found myself starting a new job and a new research project. My job, of course, was as a conservation scientist here at the Chicago Botanic Garden, and the research project had me sitting on the side of a road at dusk in Pueblo West, Colorado. I sat there in front of a group of plants that produce lovely-smelling flowers, waiting for their impressive pollinators to show up.

Banning Species Blindness in Budding Botanists

I scratch my head and wipe the sweat from my brow. One of my summer interns found a little plant, under a bunch of big plants, and we thought for a second it might be the same as the big plants, but it is definitely different. It’s our first field day. We don’t know what this plant is called, and it’s a hot and humid summer day in Chicago, and we have been searching through our identification guidebooks for what seems like forever. “Is it this one?” we ask each other, pointing to pictures in the book where the leaves kinda sorta look like our little plant.

The Hidden Partners of the Vanilla Orchid

Vanilla cookies, vanilla perfume, and everything vanilla swept through my nostrils at an Orchid Show scented display one year. The sweet smell was a great way to show many Chicago Botanic Garden visitors that vanilla comes from the fruits of the vanilla orchid (Vanilla planifolia).

As a docent at that Show, I was eager to show off the Garden’s vanilla plant (located in the Tropical Greenhouse next to the banana trees), because I knew that may visitors didn’t know that they had an orchid in their spice cabinet.

Trouble for Monarchs — But You Can Help

Monarch butterflies have left their overwintering sites in Mexico and are heading back toward the Midwest, including the Chicago area.

In the 1990s, hundreds of millions of monarchs made the journey each fall from the northern plains of the United States and Canada to forested sites north of Mexico City. In western North America, more than a million monarchs made a shorter flight to tree groves on California’s coast. However, monarch numbers have been declining for more than a decade, and scientists documented record low numbers in the 2010s.
