The genus is a member of the subfamily Cypripedioideae, commonly referred to as the Lady’s or Venus’ Slipper Orchids, so named from the unusual shape of the pouch (labellum) of the flower, which was said to resemble a lady’s slipper. The leaves can be short and rounded or long and narrow, and typically have a mottled pattern. When older shoots die, newer ones take over. Each new shoot only blooms once when it is fully grown, producing a raceme between the fleshy, succulent leaves.
