As the name implies, the root, really a tuber, is edible and tastes like a cucumber…although I personally have not yanked one out of the ground to munch upon it. I am relying on the report in good faith. The plant grows to between 12-36 inches and flowers in late spring and early summer. The fruits are berries which are dark red to purple and I have seen nothing to indicate they are edible. The plant is considered as becoming rare so pulling the roots is not encouraged. Whether they are edible or not, the berries produce new plants so leaving them for the future is a good idea.
Indian Cucumber Root-Medeola virginiana is a member of the Lily family and the only species in it genus.
I’ve never photographed the berries but will try to remember to do so later in the summer. The plant is taller than shown here but I concentrated on the flower.
