Ram's head lady's slipper (Cypripedium arietinum)

Description

Cypripedium arietinum is a small lady's slipper which typically has 3, but sometimes 4-5, leaves. This species has a single flower on each stem having divided lateral sepals and a unique hairy pouch shaped like an funnel. The purplish-red flower has light venation and is white at the lip. The plant grows to 10-40 cm (4-15.5 in), and the flowers may reach 1-2 cm (0.5-1 in). It flowers from May to June, producing brownish-green flowers with a pink and white lip. The ram's head lady's slipper is difficult to cultivate, and rarely survives transplantation to a garden from the wild. It should never be removed from any natural area.
