Lamprocapnos spectabilis (formerly Dicentra spectabilis); also known as old-fashioned bleeding-heart, Venus's car, Lady in a bath, Dutchman's trousers, or Lyre-flower is a rhizomatous perennial plant native to eastern Asia from Siberia south to Japan. It is a popular ornamental plant for flower gardens in temperate climates, and is also used in floristry as a cut flower for Valentine's Day. It usually has red heart-shaped flowers with white tips which droop from arching flower stems in late spring and early summer. White-flowered forms are also cultivated.
In a moist and cool climate, it will grow in full sun, but in warmer and drier climates it requires some shade.
Aphids, slugs and snails sometimes feed on the leaves. Clumps of dicentra remain compact for many years and do not need dividing. They have brittle roots which are easily damaged when disturbed. Root cuttings should be taken in spring.
