Vigorous, sun and heat tolerant, Dicentra 'King of Hearts' (Fern-Leaf Bleeding Heart) is a compact, bushy perennial noted for its arching sprays of large, deep rose heart-shaped flowers. Blooming over a very long season extending from late spring to early fall in cool summer climates, the flowers dangle gracefully above a sumptuous foliage mound of feathery, finely-divided, blue-green leaves. In warmer areas, flowering will stop in the heat of the summer and may start again in late summer to early fall. Perfect to brighten a shady border or to enchant passersby all season long.
- Grows in a compact clump, up to 8-10 in. tall (20-25 cm) and 12 in. wide (30 cm). Unlike Common Bleeding Hearts (Dicentra spectabilis), it will not go dormant in midsummer as long as the soil is kept moist.
- Thrives in part shade and is easily grown in fertile, humus-rich, moist, well-drained soils. It is full shade tolerant but be aware that too much shade will result in few flowers. It can be grown in full sun in the coolest part of its range provided the soil is kept consistently moist.
- Great for beds and borders, edging, underplanting shrubs or banks and slopes.
- Deer and rabbit resistant
- Apply a thin layer of compost each spring, followed by a 2-in. (5 cm) layer of mulch to retain moisture and control weeds.
- Plant bareroot Dicentra in early spring while the plants are still dormant.
- After the first killing frost, cut stems back to an inch or two above soil line.
- All parts cause severe discomfort if eaten.
