Bluebeard is a perennial native to Japan, Korea, and China. It is the only member of the genus Tripora. It can be grown in many North American climates, and may be a garden escape in some areas. It prefers well-drained soils with average moisture. Its showy flowers attract bees, butterflies, and other desirable insects.
Plants: Plants reach up to 5' (1.5 m) in height. Stems are covered with fine hairs.
Flowers: Flowers are blue-purple, occurring in terminal and axial clusters on long, sinuous branched petioles. Each flower has long white curved stamens tipped with yellow anthers, and five lobes, including a prominent bottom lobe that is white with blue spots (or, if you prefer, blue with white spots). Flowers appear from August to September.
Fruits: The base of each flower develops four spherical seed pods, each about ¹/₁₆" (2 mm) in diameter.
