Patrinia is a genus of 15 species of clump-forming perennials that bear small cup-shaped yellow or white flowers on long, usually leafless stems. Patrinia forms mounds of deeply cut or lobed leaves. The flowers appear in flat-topped clusters blooming in summer.
Patrinia are a good choice for borders, woodland gardens, and rock gardens. Patrinia can be mixed with other border perennials. They grow best in moist soil in shade or partial shade.
Patrinia are native to grassy mountain habitats in Japan and Siberia.
