Aplectrum hymale is a relatively common orchid in Missouri, preferring rich mesic forests, particularly along stream and river banks. It is known by two common names that are both widely used. “Adam and Eve Orchid” is used due to the presence of twin underground corms. The leaf of the current year is connected to the youngest corm (Eve), and is an offshoot of the previous corm (Adam).
The other common name, “puttyroot orchid”, is given to this species due to the putty-like consistency of the corms that were sometimes eaten, most likely for medicinal purposes.
A. hymale is unusual in that it exhibits an alternate vegetative cycle. Leaves of this plant (one leaf per plant) develop in the autumn and overwinter. The leaves begin to senesce in the spring and have almost completely withered by the time the plants are in full bloom, or shortly after. In the preceding photo you can see the leaves at the time of flower shoot formation.
These plants typically bloom in early to mid-May in Missouri. By the time June rolls around the leaves will most likely be completely deteriorated and the only sign of the plant over the summer is the flowering stem (raceme) and developing fruit capsules.
