California lady’s slipper is a herbaceous perennial and a member of the orchid family, Orchidaceae. It is native to the mountains of northern California and southwestern Oregon where it grows in serpentine wetlands such as seeps, bogs, fens, and margins of woodland streams in open coniferous forests. Plants may grow up to 4′ tall and often form very large clumps. Stems each carry 5-10 hairy, oval leaves that are pleated and 6-8″ long. Ten to twelve one flowers are carried on each stem in the axils of leafy bracts in late spring to early summer. The flowers are about 1″ across and have yellowish brown sepals and petals, and a white pouch sometimes with brown or pink touches. The genus name, Cypripedium, comes from the Greek words Kypris referring to the island where Venus was worshiped, and pedilon, meaning slipper referring to the shape of the flower. The specific epithet, californicum, is the Latinized form of the plants native home state.
