Archives For The Orchid Show

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.

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.

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

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

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.

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.

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.

Some nurseries will care for your orchids if you’re busy or on vacation, or simply prefer to have experts raise them until the plants are ready to bloom. “As your orchid begins to send up a bloom spike, it is tenderly staked and tied, ready to return to you as it comes into bloom,” says Hamilton Orchids & Plantscapes in Sonoma, California.

Studying Fungi Amid the Ghost Orchids

Undercover Science

Julianne Beck —  January 24, 2017 — 1 Comment

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.

There’s only one reason orchid flowers look so beautiful and smell so good: to attract a pollinator. Some orchids engage in mimicry, evolving to look like the pollinator they’re trying to lure. Other orchids look familiar to humans, even though there is no connection for the flower. There’s a word for the phenomenon, pareidolia.

Roll over each orchid to reveal its look-alike. See an array of beautiful orchids at the Orchid Show at the Chicago Botanic Garden, through March 13. 

Ophrys apifera, "bee orchid"Bee


Ophrys apifera

Known as the bee orchid, this species not only looks like a female bee, but it smells like one, too. Male bees land, hoping to mate, only to be fooled into transporting pollen from one flower to another.

Caleana major,  "flying duck orchid"Duck


Caleana major

Animals as large as a duck are too big to pollinate an orchid…but when the sawflies that are the right size land on the “beak” or labellum of the flower, their weight springs them downward into contact with the pollen.

Psychopsis papilio, "butterfly orchids"Atlas moth


Psychopsis papilio

Looks like a butterfly, is named for the butterfly (papilio is the Latin word), and flutters like a butterfly at the top of its long, delicate step. Yes, it’s pollinated by butterflies.

Dracula, "monkey orchid"Monkey


Dracula
sp.

Orchids in the genus Dracula are called monkey orchids, but their charmingly face-like flowers are calling out to fruit fly pollinators, not to monkeys.

Brassia, "spider orchid"Spider


Brassia
sp.

Spider orchids are wily—they developed the look of a spider in order to attract spider wasps as pollinators. The wasp lands on the labellum, tries to sting it, gets covered in pollen instead, and flies off to its next prey.

Peristeria elata, "dove orchid"Dove


Peristeria elata

Look deep into the center of a dove orchid to see the tiny bird with widespread wings. When a Euglossine bee lands on the flower’s hinged lip, it trips a hinge that throws the bee against the pollen-bearing column (the head of the dove). The national flower of Panama, the dove orchid is increasingly rare.
