Growing Dicentra (Bleeding Heart): Shade Garden Classic

Introduction

Dicentra, commonly called bleeding heart, is a beloved shade perennial with arching stems of heart‑shaped flowers in spring. D. spectabilis grows 2–3 ft tall; smaller cultivars bloom longer and offer attractive blue‑green foliage through fall.

Planting

Plant potted dicentra with crown at soil level. Bareroot D. spectabilis: crown 2 inches deep; smaller bareroot types: 1 inch deep. Space 18–24 inches apart.

Light and Water

Partial to full shade; morning sun with afternoon shade yields best flowering. Keep soil consistently moist—D. spectabilis goes dormant if soil dries in summer.

Soil and Fertilizer

Rich, evenly moist, slightly acidic soil (pH 6.0–6.5) is ideal. Mulch 2 inches to conserve moisture. Apply compost or granular fertilizer in spring.

Pests and Diseases

Slugs and snails may nibble foliage; use baits or hand‑pick. Crown rot occurs in poorly drained soil—ensure good drainage and air circulation. Keep mulch away from crowns.

Companions and Seasonal Care

Pair with aquilegia, ferns, tiarella, campanula, hostas, and pulmonaria. Remove spent flower stems to encourage rebloom on smaller types. Divide in early spring if desired. Cut back foliage after frost; apply winter mulch after ground freezes.

Calendar of Care

• Early Spring: Fertilize, divide, water if dry.
• Mid‑Spring: Mulch, scout for slugs.
• Late Spring: Water regularly.
• Summer: Fill gaps with annuals where D. spectabilis is dormant; groom yellowing foliage.
• Fall: Cut back, apply winter mulch.
