About this plant
Cypripedium formosanum produces elegant, pouch-shaped flowers in soft rose to lavender pink, marked with deeper veining and a gently inflated lip. The blooms are carried above pleated, oval leaves with pronounced ribbing, creating a bold architectural presence. Upright stems support single flowers that hold their form well through the flowering period.
Blooming in late spring to early summer, this species is native to the mountains of Taiwan. It is valued in woodland gardens, shade borders, and specialty plantings, where its refined flowers pair naturally with ferns and spring ephemerals, offering seasonal interest and a distinctive orchid character in carefully designed landscapes.
