Clark Riley has been an active orchid grower since 1957. At the age of six, he got his first plant, a probably-collected Yellow Ladyslipper (Cypripedium pubescens) from a perennial nursery. The plant died a miserable death in a short time, but not before blooming and cementing a love of orchids that has lasted over half a century. He has labored ever since to make amends by promoting the sound cultivation of Ladyslippers. He grows a wide range of orchids, including several thousand terrestrials, hardy species, and ladyslippers, Brazilian Laelias, and specialty Phalaenopsis, often from seed. He was the producer for the book and CD of Proceeding of the North American Native Terrestrial Orchid Conference. He is a member of the Maryland Orchid Society and the American Orchid Society.
