Dicentra (Greek dís "twice", kéntron "spur"),[3] known as bleeding-hearts, is a genus of eight species of herbaceous plants with oddly shaped flowers and finely divided leaves, native to eastern Asia and North America.


Flowers have two tiny sepals and four petals. The flowers are bisymmetric: the two outer petals are spurred or pouched at the base and curved outwards or backwards at the tip, and the two inner ones with or without a crest 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 stems as well as from the root.[4] Each of the two compound stamens is composed of one median and two lateral half stamens fused together. The stamens and pistil are held between the inner petals.

Seeds with elaiosomes are borne in long capsules.

All parts are poisonous if ingested.
Current species

The genus Dicentra includes plants whose flowers and leaves grow on stems directly from the roots. Species with branching stems used to be included in the genus, but have now been moved to other genera.[4]

Two bleeding-heart hybrids: Dicentra 'King of Hearts' (deep pink) and Dicentra 'Ivory Hearts' (white)

There are several hybrids and cultivars involving Dicentra eximia, Dicentra formosa, and Dicentra peregrina, including (those marked agm have gained the Royal Horticultural Society's Award of Garden Merit):-[5]

Dicentra 'Aurora' — Dicentra formosa × Dicentra eximia — white flowers
D. formosa 'Bacchanal' (agm)[6] — deep red
Dicentra 'Ivory Hearts' — Dicentra peregrina × Dicentra eximia 'Alba' — white
Dicentra 'King of Hearts' — Dicentra peregrina × (Dicentra formosa subsp. oregana × Dicentra eximia)
D. formosa 'Langtrees' (agm)[7]
Dicentra 'Luxuriant' (agm)[8] — Dicentra formosa × Dicentra eximia × Dicentra peregrina
Dicentra 'Stuart Boothman' (agm)[9]

Hybrids involving Dicentra peregrina are often intolerant of hot, humid climates and sun, like the species itself.
