Today I’m showing a couple of orchids from the Platanthera genus. The title of this post suggests these are both prairie obligates, however this is not true with the first species shown here – P. lacera, the green fringed-orchid. P. lacera most likely appears in more different habitat types than any other orchid in the state. You can find this orchid in places ranging from dry hay fields to fens to forest habitats. The sole individual I was able to find this year was on a reconstructed prairie in Franklin County, MO. Unfortunately, this plant was several days past peak bloom so, I’ll be looking for others in the coming seasons.
Sarah and I had quite a treat when we made a long day trip to north-western MO in mid-June of this year. We were able to find a few western prairie fringed-orchids just past peak bloom. This was a first for both of us. Platanthera praeclara is a globally endangered species and listed as an S1 species (critically imperiled) by the state of Missouri. This is just another of the many species in such a status due to the unregulated destruction of prairie habitat in the midwest for crop cultivation over the past 200 years. The large white flowers of this species are pollinated by nocturnal sphinx moths – a potential photography project in years to come.
