Summary

Lamprocapnos spectabilis is a rhizomatous, clump-forming herbaceous perennial native to Siberia, China, Korea, and Japan. It grows to about 0.5–1 m tall with arching stems bearing pendant heart-shaped flowers in pink or white, each with a white inner petal that creates the classic bleeding-heart appearance. A mound of mid-green, divided leaves sits at the base, and the plant typically forms a 0.3–0.6 m spread.

It prefers moist, fertile, humus-rich soil that is neutral to slightly alkaline and a position in partial to full shade, though sun is tolerated if moisture is reliable. It is hardy in USDA zones 3–9 and can be propagated by division in early spring or after leaf drop, or by root cuttings in winter; self-seeding is possible. Slugs and snails may occur; the plant is toxic if ingested and foliage may irritate skin. This species suits shaded borders, woodland gardens, and underplanting for structural contrast with its arching stems and showy blooms.
