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.

Colleton County, South Carolina is in USDA Zone 8b. The average last spring frost is March 10 and the first fall frost is November 13, giving you a growing season of approximately 248 days.

At an elevation of 265 feet, Colleton County receives approximately 58.2 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 96°F, so Bleeding Hearts may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Bleeding Hearts will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Bleeding Hearts root diseases.

Bleeding Hearts Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Bleeding Hearts needs ~1,650 GDD — county provides 5,456 GDD Excellent fit

Growing Tips for Bleeding Hearts in Colleton County

Direct sow Bleeding Hearts outdoors after March 10 in Colleton County when soil has warmed and frost danger has passed.

Sandy soil in Colleton County dries quickly — mulch Bleeding Hearts with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

With summer highs reaching 96°F in Colleton County, provide afternoon shade for Bleeding Hearts and water deeply in the morning.

General growing tips

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.
