Don’t trust your eyes—that leaf is actually a butterfly

The orange dead leaf (Kallima inachus)

Patrick Sbordone —  July 20, 2017 — Leave a comment

As the season has been progressing at Butterflies & Blooms at the Chicago Botanic Garden, we have been lucky enough to receive a very special butterfly species and a definite crowd-pleaser: the orange dead leaf (Kallima inachus)

If we didn’t point out this character to guests, no one would ever suspect that they were looking at a butterfly.

I like to describe the orange dead leaf butterfly as being able to mimic a dead leaf better than an actual dead leaf can. When it closes its wings, the butterfly has a perfectly ovate silhouette, complete with both a pointed leaf apex at the front tip and a petiole, or the stalk that attaches leaf to stem, on the hindside. The wing is a drab brown, with leaf vein arrangement very similar to that of a flowering dogwood. The orange dead leaf butterfly is at home in broadleaf forests of India, where it blends in with dead foliage during the dry season, going unnoticed by all but the sharpest predators. Here at Butterflies & Blooms, this butterfly seems to seek out dead, brown leaves in the tree canopies and uses them as a place to blend in. I always get a kick out of showing people that one of those dead leaves is not what it seems.

The butterfly has another surprise for visitors: It has incredibly vivid coloration on the dorsal side of its wings. When the orange dead leaf opens its wings to sun itself or take flight, it shows off its navy blue iridescent wings, with a bright orange stripe on each of the forewings.

We have several other butterfly species that also use one side of their wings to resemble dead foliage, including the autumn leaf (Doleschallia bisaltide) and the great orange tip (Hebomoia glaucippe). However, these species have not mastered the art of camouflage quite like Kallima inachus. Come over to Butterflies & Blooms to check out this fascinating butterfly.

While you are here, take a look at the serviceberry tree just to the left of the pupae chamber. We have an unprecedented seven giant atlas moths perched on the tree branches like Christmas tree ornaments. Also, don’t miss all of the blooms: The recent rainy weather has undoubtedly helped the Butterflies & Blooms garden become more floriferous.

This summer, the Chicago Botanic Garden is transforming—with tall coconut palm trees and other iconic plants of Brazil, inspired by the designs of renowned Brazilian landscape designer Roberto Burle Marx.

The making of Brazil in the Garden started with an unlikely source, a family’s brick townhouse in Philadelphia.

Two members of the Garden’s design team visited the townhouse last summer, not sure what to expect. What they found was a treasure trove of original work by Burle Marx (1909–94), including stacks of rare, numbered lithographs, rolled tapestries too large to hang, and framed paintings. Some of the pieces, which had never been on public display, are now part of an exclusive Burle Marx exhibition at the Garden.

The collection had been in private hands, owned by landscape architect Conrad Hamerman and kept on the third story of his townhouse. When Hamerman died in 2014, his family inherited the pieces. Hamerman was a close friend of Burle Marx, and represented his work in the United States; Burle Marx gave him the pieces as gifts and as payment for his services.

Through a contact, the Garden’s exhibition manager Gabriel Hutchison and senior designer Nancy Snyder met with Hamerman’s wife and daughter in Philadelphia to discuss Burle Marx’s artistic legacy and his friendship with Conrad Hamerman. The Garden’s Burle Marx exhibition reveals a rare glimpse of Burle Marx as an artist known for his bold colors, abstract shapes, and modernist style.

Hutchison and Snyder spent two days reviewing and evaluating the material for possible exhibition. “The collection was so much more diverse than I had imagined—sketches, oil paintings, landscape plans, and painted canvas wall hangings,” Snyder said. “This was really an honor to work on, and all along it felt like exhibiting the work was a suitable tribute to the rich friendship between the Hamermans and Roberto Burle Marx.”

Hamerman and Burle Marx met as young men in Brazil. Hamerman was a landscape designer who wanted to become an artist, and Burle Marx was an artist who wanted to become a landscape designer. Above all, they were both avid plant people. Their mutual love of plants, art, and design formed the basis of a lasting friendship that inspired them to travel on many expeditions to collect plants together.

“Conrad was a professional colleague of Roberto’s and collaborated with him a lot,” said Hutchison. “Over the years they became close friends, and although Conrad enjoyed doing his own work, I think he was most passionate about working with Roberto.”

The two even taught university courses together, which is where landscape architect Andrew Durham first encountered Burle Marx’s work. A former student and family friend of Hamerman’s, Durham arranged the loan of pieces from the family’s personal collection for the Garden’s exhibition.

Roberto Burle Marx exhibition

The Roberto Burle Marx exhibition runs through September 10, 2017.

“One thing that made Hamerman unique as a professor was his close friendship with Roberto Burle Marx,” said Durham. “Our class traveled for a month to Brazil, where Burle Marx personally showed us his gardens. That trip changed many of us forever, and I’ve embedded in my own work much of what I learned from Burle Marx’s use of texture and color.”

Though known for revolutionizing tropical landscape design, Burle Marx also worked in other artistic mediums. The paintings and textiles at the Garden exhibition showcase his style of vast swaths of bold hues, cubist influences, and contrasting fabrics.

See the Roberto Burle Marx exhibition, open 9 a.m. to 7 p.m. in the Regenstein Center, Joutras Gallery, through September 10, 2017.

USO families and veterans were welcomed on June 25 to a special day at the Chicago Botanic Garden. A gift from the Annie and Gregory K. Jones family provided the families and veterans with a day of fun experiences: tram tours, admission to the Model Railroad Garden: Landmarks of America and Butterflies & Blooms exhibits, lunch, exploration at the Kleinman Family Cove, nature play at the Regenstein Learning Campus, and creating a mini terrarium in the Buehler Enabling Garden. 

The Garden’s horticultural therapy department drew on their experiences working with veterans and their families as they planned a plant-based activity that would celebrate the strengths of these folks. Succulent plants were a natural choice. Add colored aquarium gravel and a portable container, and you’ve got a beautiful tribute to the pride of being a member of a military family. So, here is a fun way to consider this event:

How is a plant like a member of a military family?

Succulent plants

Succulent plant: By deftly storing water, succulent plants live just fine under extremely hot and dry conditions.

Military spouse: By using resources wisely, a military spouse stretches money, time, and love to make sure the whole family is taken care of, wherever they may be.

Succulent plant

Succulent plant: Develops a tough exterior to endure harsh conditions.

Military parent: Develops coping skills and the ability to play both mom and dad roles to endure long deployments.

Succulent plants

Succulent plants: So many colors, leaf shapes, growth habits, and unique beauty—yet all have key traits in common.

Military kid: Powerfully diverse in appearance, personality, and beauty—yet all have key traits in common.

Succulent plant

Succulent plants: Belong to many plant families, but all are classified as succulents because of the features they have in common.

Military families: Each family is unique, and many include extended family members for support, yet each family takes pride in—and draws strength from—the traditions, support, and high purpose that being part of the military offers.

One striking thing about the day was the eager participation of everyone who planned and worked on that day. Garden volunteers raced to sign up for shifts. Many cited their own family members in service and their strong desire to honor those who keep us safe and free. The USO of Illinois had an equally eager corps of volunteers who came to the Garden early on a Saturday morning to get the “goodie bags” filled and to register everyone. 

Kay Knight, horticultural therapy coordinator, was the Garden’s point person for planning the day. Kay worked with departments across the Garden and with USO of Illinois to make sure everything ran smoothly. According to the many, many compliments and thanks expressed, Kay succeeded! 

The USO families had fun doing activities together and enjoyed the red-carpet treatment.

Flora Brasil

Lenhardt Library celebrates Brazil in the Garden with a “Flora Brasil” special collections exhibition

Leora Siegel —  July 7, 2017 — Leave a comment

Brazil’s native flora has amazing diversity with differing biomes, including tropical rainforest, subtropical forest, tropical savanna, mangrove forest, tropical dry forest, wetland, and savanna.

Of the approximate 400,000 known plant species in the world, 55,000 are endemic to Brazil, and most of these are from the Amazon forest.

Brazilian bromeliads in the Crescent Garden

Bromeliads abound this summer throughout the Garden. There are more than 3,000 known species of bromeliads; 650 of these are native to Brazil. Many bromeliads have leaves that are spiraled and called a rosette. At the base of the rosette, the leaves may grow in an overlapping and tight form to become a place for water to collect.

Many of the foods we eat (like acai), industrial products we use (rubber tree and mahogany), medicines—even our houseplants in the Chicago region (orchids), depend on plants from this region. The unique flora of this area continues to be threatened by deforestation and urbanization, and plant species are at risk.

Books on display through October 15, 2017, in the Lenhardt Library’s Flora Brasil exhibition depict a plant exploration map, Brazilian aroid, and Brazilian bromeliads. An untitled original artwork by Brazilian landscape designer Roberto Burle Marx on loan from Longwood Gardens complements our main Joutras Galley exhibition of Marx’s work.

The library exhibition opens with an eighteenth-century map of South America with “the coast of Brazil being corrected” bound into the third edition in English of Voyage to South America: Describing, at Large, the Spanish Cities, Towns, Provinces on That Extensive Continent by Don Antonio de Ulloa and Don George Juan, 1772. Ulloa and Juan explored the region, observing and describing the flora, fauna, geology, minerals, indigenous population, and politics they encountered.

ILLUSTRATION: Philodendron cannaefolium by Heinrich Schott

Philodendron cannaefolium ‘Burle Marx’, a 24” x 30” detailed chromolithograph that is both scientifically accurate and stunning from Aroideae Maximilianae by Heinrich Schott, 1879.

A Brazilian aroid Philodendron cannaefolium (today known as Philodendron ‘Burle Marx’) is the centerpiece with a 24-inch-by-30-inch detailed chromolithograph that is both scientifically accurate and stunning. This 1879 work, Aroideae Maximilianae by Heinrich Schott, features 42 plates with delicate colors and clean lines. Schott was an Austrian botanist who traveled in Brazil from 1817 to 1821. He specialized in Araceae and throughout his career, he named 587 new-to-science species of aroids; by comparison, Linnaeus named six aroid species. 

Come also learn about Margaret Mee, who was an exceptional botanical artist, plant explorer, and environmentalist. Four reproductions of Mee’s “Brazilian Bromeliads” are on view. These are from a limited edition set published in Brazil in 1992.

Mee traveled to Brazil often, and went on fifteen botanical expeditions, mainly into the Amazon region. On these expeditions, she discovered several new plant species, painted more than 400 gouache pieces, and kept travel diaries detailing her adventures. Her passion for Brazilian flora coincided with the large-scale commercialization of the Amazon rainforest. She became an outspoken environmentalist, calling attention to the dangerous destruction of the biodiverse region.

Noted Brazilian landscape architect Roberto Burle Marx cultivated plants that Mee brought back from her expeditions and used them in his landscape designs. Known for his bright and bold color choices, Marx was inspired by Mee’s paintings. Like Mee, he was concerned about the environmental impacts of the commercialization of the Brazilian Amazonian region.

The fourth of July is upon us, and while many beautiful flowers can be found in patriotic shades of red and white, the color blue is very difficult to find at the Garden.

In fact, blue is a rare sight in the entire natural world. Less than ten percent of the plant kingdom features blue flowers, which is extraordinary, since pollinators don’t seem to have a problem with them. Scientists have been investigating the origins of blue flowers for a long time, and it was not until recently that they came up with a result.

Flower colors are based on pigments that include anthoxanthins and anthocyanins. Anthoxanthin colors contribute to yellow flower petals and are quite common in the plant world. Anthocyanin colors impart red, purple, and blue in blooms, but are found much less often in flora. For anthocyanin to steer blue, complex scenarios must occur. Most often, metal atoms and ions interact with the pigment to modify the color. In addition, they alter the pH of cellular fluids to be alkaline, while most organisms have an acid or neutral chemistry.

What is thought-provoking is that a red rose and a blue cornflower (Centurea cyanus) contain the same anthocyanin pigments. Cardinal flower (Lobelia cardinalis) and big blue lobelia (Lobelia siphilitica) are of the same genus, but one flower is red and the other is blue. It is the rare and complex modification of that pigment that contributes to the blue flower being blue. More surprising is that hybridizers have yet to develop a truly blue rose or carnation (without resorting to pigmenting water, which a plant takes up, changing the color of its bloom).

Since blue is uncommon, visitors at the Garden should take extra time to enjoy the flowers in the English Walled Garden, where they will find containers full of adorable Felicia daisy (Felicia heterophylla ‘Forever Blue’) right beside sky-colored plants called southern star (Tweedia caerulea ‘Heaven Born’)—a member of the milkweed family. In addition, there are cool-hued drifts of Magadi™ electric blue lobelia (Lobelia erinus ‘KLELE10670’) weaving throughout several garden beds, as well as spilling out of containers.

Another area with a good deal of blue flowers is the Heritage Garden. In the plant family area, you will find intricate love-in-a-mist (Nigella damascena ‘Miss Jekyll’) blossoms mingling with wispy yet showy Siberian larkspur (Delphinium grandiflorum ‘Blue Butterfly’). And nearby, nile lily flowers (Agapanthus ‘Queen Anne’) explode like bright blue fireworks. And finally, in the geographic area, sea holly (Eryngium planum) creates a shiny and spiky blue accent.

While it is difficult to achieve blue pigments in plants, the ones that did are certainly successful in this world. The word “perseverance” comes to mind, which just so happens to be what the blue within the American flag represents. Anyone who has marveled at a field of Texas bluebonnets (Lupinus texensis) and witnessed the huge number of bees and butterflies working to gather its pollen would agree.
