Cypripedium 'Ulla Silkens' is a stunning 1996 hybrid from Svante Malmgren. This vigorous hybrid strain is a cross of the American Cypripedium reginae x the rare Chinese Cypripedium flavum. Cypripedium 'Ulla Silkens' is much easier to grow than its parents and will take a good bit of sun in cooler climates, but still prefers moist alkaline soils. The 2' tall flowering stalks that appear in mid- to late-June are topped with huge slippers of burgundy and white, backed by three large, pure white sepals. The clumps will become quite large with nearly 100 flowers per clump. Our offerings are flowering-sized plants grown from seed.
