Cypripedium parviflorum var. pubescens (LARGE YELLOW LADY’S-SLIPPER)


The large yellow lady’s slipper orchid (Cypripedium parviflorum var. pubescens) is native to much of eastern North America, growing in moist and mesic woods, on hillsides, along streams, and in the drier areas of bogs and fens. Like many native orchids, it is threatened by habitat destruction and indiscriminate collecting. Although many orchid species have a well-earned reputation for being finicky about habitat, the large yellow lady’s slipper can easily be grown in the home garden, provided its cultural requirements are met. A good woodland situation with some morning sunlight and good drainage are its chief requirements. The plant associates listed below will provide a sense of the conditions it prefers.
