Ohio Orchids 1

When most people think of orchids, what often comes to mind are big corsages and frilly tropical epiphytes. But there are many wild terrestrial orchids that, to me, add unsurpassed beauty to the world of wildflowers. 

We are fortunate in Ohio to have over 40 different species of wild orchids, which range from eye-poppingly gorgeous to nearly inconspicuous. 

Orchid seeds are extremely small and almost dust-like. They contain no food for the developing plant (think about all the food contained in a bean or sunflower seed; orchids have none of that) and fungi are necessary to supply nutrients for germination and growth. The symbiotic relationships between the roots of orchids and a variety of fungi are called mycorrhizae. All orchids depend on fungi to supply some of their nutrients at some point in their life cycle. Many adult orchids retain the symbiotic relationship with fungi, although the benefits to the adult photosynthetic orchid and the fungus remain largely unexplored. Some orchids are non-photosynthetic and they are likely entirely dependent on the fungus for energy. Apparently, when the orchids are older, they pass nutrients to the fungi, making it a mutually beneficial relationship. Because of these important relationships with certain fungi, attempts to transplant these orchids are usually futile. 

Anyway, I am fascinated by these plants and we are making an effort to see and photograph as many Ohio wild orchids this year as we can. Many orchids require habitats that are rare or are threatened by development so finding them is a special occasion worthy of celebration and lots of photos! Here is just a small sampling of Ohio's beautiful orchids; more will follow.

One of the first orchids to bloom in the spring is one of my favorites, the showy orchis (Galearis spectabilis). What a stunner! 

Found in rich deciduous woodlands, this plant has a wide range throughout the eastern and midwestern U.S. This particular plant and the next three species were found in Shawnee State Forest in southern Ohio. This orchid-rich area drew us to register for Flora-Quest, a wonderful event at the end of April that featured excellent botanical field trips, lots of butterflies and even moths! I could blog for weeks about what we saw!

Many hikers are quite familiar with the pink lady’s slipper (Cypripedium acaule). This plant grows in a variety of woodland habitats and blooms in early spring. It is very slow growing and, like most orchids, transplanting it is rarely successful. The structure of orchid flowers is quite variable, but all are designed to attract pollinators. In the case of the pink lady's slipper, the flower is pollinated by bees, which enter the pouch and can only exit by brushing against structures that remove pollen from a previous flower. Then the bee picks up new pollen on its way out.

Here is a side view:

The next gorgeous orchid that we spotted at FloraQuest was the incomparable yellow lady's slipper (Cypripedium parvifolium). It often occurs in clumps and can be quite showy. The twisted sepals definitely add to its exotic appearance.

Here is a rare beauty that I thought I would never see. The leaders at Flora-Quest knew where to look, though, and we were fortunate to see this incomparable specimen:

This orchid is called a large whorled pogonia (Isotria verticillata). It occurs throughout the eastern U.S. but is never particularly common. It requires acid soils, and prefers streambanks and woodlands. Here is the front view:

Isn't that amazing? It really makes me think hard about how and why a flower has evolved into this unusual configuration. I sure don't have all the answers, but I know it has to do with attracting suitable pollinators!

I hope that these four orchids whet your appetite for more. I'll soon have another post covering some of the other Ohio orchids, both showy and inconspicuous!

Wild Hyacinths and More

What a spring it has been! It started slowly but the flowers and birds have been spectacular. We have been out and about a lot, and I have so much I'd like to blog about! Life has intervened in a big way, however, and I have definitely fallen behind. I'll try to catch up if I can!

Last weekend we headed up to Lake Erie to take part in what has become quite a spring pilgrimage for literally thousands of people: the Biggest Week in American Birding, which celebrates the spring bird migration. Although it was cold, windy and crowded, we had a great time. Here are just a few of the gorgeous warblers that were nearly at eye level at Magee Marsh:

On the way home we had a much quieter nature experience which was just as spectacular as the warblers were. We stopped at Stratford Woods State Nature Preserve, just south of Delaware, Ohio. Owned and operated by the Stratford Ecological Center, the preserve features loop trails through lush woodlands which host an excellent spring wildflower display. We were quite fortunate to visit at the peak of the preserve's most spectacular wildflower, the Wild Hyacinth. Growing in moist, low areas of the preserve were acres of these lovely spikes, which are a delicate blue:

A couple of closer looks reveal details of the flower structures:

Other flowers were also at their peak. One of these, the Green Dragon, is definitely one of the strangest I've ever encountered. In fact, I had never even heard of it until a few years ago, despite 40 years of interest in wildflowers. It is pretty difficult to photograph, but here it is in all its weirdness:

Here is a closeup of the flower, with its odd yellow "lure" jutting out, presumably to attract a pollinator:

The flower is pretty inconspicuous, but the leaves are distinctive and spotting the leaves is about the only way I have ever found it. Preferred habitats include woodlands near springs and vernal pools, and it is indicative of undisturbed forest. It often occurs near its close relative, the Jack-in-the-Pulpit, and in fact we found a Jack just down the trail:

Stratford had many other flowers in bloom; one of my favorites, which is quite common, is the Wild Geranium:

Our hike at Stratford was a great way to end a very special weekend!
