When to Plant Bleeding Hearts in Gladwin County, MI
Bleeding Hearts (Lamprocapnos spectabilis) are elegant woodland perennials producing arching stems hung with distinctive heart-shaped pink or white flowers with protruding inner petals — the "drops" beneath each heart. A beloved heirloom perennial from Asia, bleeding hearts emerge vigorously in spring, bloom prolifically for 4–6 weeks, and then go dormant in summer heat — a natural die-back that is entirely normal. The dormancy gap should be planned for by interplanting with summer-emerging hostas, ferns, or impatiens. Fringed bleeding heart (Dicentra eximia), a US native, has a longer bloom season and does not go fully dormant. All parts are toxic if ingested.

Growing Tips for Gladwin County
Plant bare-root crowns in early spring as soon as soil is workable, or in fall at least 6 weeks before hard freeze. Set eyes 1–2 inches below soil level. Morning sun with afternoon shade is ideal; deep shade is tolerated but reduces bloom. Keep moist but well-drained — will not tolerate waterlogged soil. After flowering, the foliage will yellow and die back in summer heat — this is normal. Do not cut back until foliage turns fully yellow; the plant is storing energy. Mark the location to avoid disturbing crowns during summer dormancy. Divide every 4–5 years in early spring. Year 2+ plants produce the fullest flowering display.
