This handsome species, native to forest edges, meadows, and sunny banks in southwestern China, has been cultivated on sod or thatched roofs in China and Japan for centuries. Japanese women once used the powdered rhizomes as face powder. The white form was introduced to the West in 1908, while the violet-purple species arrived from Japan in 1872. Flowers attract hummingbirds and butterflies.
Arrives in a 3.5" pot.
