Also called Corpse Plant, American Ice Plant, or Ghost Flower. The translucent, waxy pipes are unique. The single nodding flower, about 1 inch long, is white or pink and turns blackish with age. Erect, usually clustered, stems bear small scales representing leaves. It grows to a height of 4 to 10 inches. It is found in moist, rich, shady woods and grows on decaying vegetable matter and is somewhat parasitic. It blooms between June and August with the blossoms followed by an oval, many-seeded capsule which becomes erect in ripening.
