Cypripedium reginae (Showy Lady's Slipper)

Showy Lady's Slipper


One of the most spectacular and beautiful Lady’s Slippers, Cypripedium reginae (Showy Lady's Slipper) is a hardy orchid boasting showy white flowers, 2 in. across (5 cm), adorned with an inflated pouch usually heavily streaked with pink or magenta. It is backed by white sepals and petals that spread out. Blooming from late spring to midsummer (depending on geographic locations), the sophisticated flowers are borne at the top of the stems, singly or in groups of 2-3. The stems bear between 5-7 large, oval, pleated, bright green leaves that have fine hairs and prominent veins. Ravishing, this plant can form a showy clump of 200 flowering stems in moist, favorable conditions, however plants with 20 or more stems is closer to the norm. Long-lived (up to 50 years), and easy to grow, Showy Lady's Slipper is a great deal tougher than it appears. It became the state flower of Minnesota in 1902 and was protected by state law in 1925. It is illegal to pick or uproot a Showy Lady's Slipper flower in Minnesota.
