A most interesting perennial with leaves arranged in two whorls on flowering plants; young plants will have just one whorl of 5+ leaves. Flowers appear in the late spring, in clusters of 3-9, in the axils of the leaves. They have a strange look with backwards curled tepals, exerted stamens and red stigmas; dark blue berries in the fall.
Its most ornamental feature shows up in the fall when the leaf blades become red-tinged at the base, contrasting with the dark purple berries.
As its common name suggests, the rhizomes are edible, with a cucumber taste and odor, and were used by the Natives Americans.
Germination: I have no personal experience with Medeola seeds yet; they are said to be best sown fresh and for me this sounds like something that if needs to stay moist (until sowing). Also I found that they need two periods of cold to germinate; it means they would germinate in the second year after sowing, unless you’re willing to shuffle Ziploc bags in and out of fridge to shorten the process.
Update: yes, Medeola is definitely in the category of what’s called ‘2 years seeds’ (2 periods of cold with 1 of warmth in between are required for germination).
