Expert tips
The key tip
Lamprocapnos spectabilis prefers dappled shade and cool part-shade; in full sun and dry soil, it fades before summer. Rich, humus-filled soil that stays fresh in spring is ideal.
The common mistake
Exposing it to hot afternoon sun hoping for more flowers.
The pro's trick
Support the stems before they flower (April) with discreet stakes: flower-laden hearts are heavy and tend to flop over.
Care
Light Exposure
Bleeding heart prefers part shade, ideally beneath deciduous trees that filter direct rays. In warm climates, avoid full south-facing exposure in the afternoon to preserve the delicate pink hue of its flowers. Too much shade reduces blooming.
Watering
Keep the soil regularly moist during growth and flowering, without waterlogging. After flowering and through summer, reduce watering since the plant enters dormancy. In autumn and winter, let the soil dry out slightly between waterings.
Soil
Choose fertile, well-draining soil enriched with organic matter (potting mix, compost). Slightly acidic to neutral pH works perfectly. Improve poor soil before planting with decomposed manure or compost.
Fertilizing
A moderate application of all-purpose fertilizer in spring (before or at the start of flowering) is sufficient. You can also work well-decomposed compost into the soil surface each year. Avoid excess nitrogen, which favors foliage at the expense of flowers.
Pruning and Cutting
No pruning is necessary. Simply remove spent flowers if you want to extend blooming slightly. Let the foliage yellow naturally before cutting it back to the base in autumn or late summer.
Diseases and Pests
The plant is generally robust and rarely troubled by disease. Watch for powdery mildew in warm, humid conditions: space plants well and ensure good air circulation. Slugs and snails may damage young leaves in spring.
Did you know?
Bleeding heart gets its romantic name from the unique shape of its hanging flowers, which genuinely resemble little pink and white hearts. In Asia, where it's native, this plant bears poetic names reflecting its beauty: "Flower of the Lyre" in Japan or "Dicentra spectabilis" in western botany, with "spectabilis" meaning precisely "remarkable" or "spectacular." It conquered European and North American gardens in the nineteenth century, becoming a cottage garden classic.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
