Dicentra (bleeding-heart; Greek dís "twice", kéntron "spur") is a genus of 8 species of perennial herbaceous plants in the fumitory family, many with heart-shaped flowers, native to eastern Asia and North America.

Contents

Description

Flowers have two tiny sepals and four petals. The petals are bisymmetric: the two outer ones are spurred or pouched at the base and curved outwards or backwards at the tip, and the two inner ones are straight and connected at the tip.

In Dicentra, all leaves are in a basal rosette and flowers are on leafless stalks. In other genera with bisymmetric heart-shaped flowers (Lamprocapnos, Dactylicapnos, Ichtyoselmis, Ehrendorferia), leaves grow on flower stalks as well as from the base.

Each of the two compound stamens is composed of four stamens fused together. The stamens and pistil are held between the inner petals.

Seeds with elaiosomes are borne in long pods.

All parts are poisonous if ingested.
