Bleeding Heart Varieties: Which Types Are Best for Overwintering?

by

Bleeding hearts are beloved perennial plants known for their charming, heart-shaped flowers and delicate appearance. They add a touch of elegance to shaded garden beds and are popular among gardeners looking for early spring color. However, choosing the right variety for overwintering is crucial to ensure your bleeding hearts survive cold climates and return year after year.

Understanding Bleeding Heart Varieties

There are several types of bleeding hearts, each with unique characteristics and hardiness levels. The most common varieties include the traditional Dicentra spectabilis, the Dicentra formosa, and the newer Dicentra eximia. Knowing their differences helps gardeners select the best options for overwintering in their regions.

  • Dicentra spectabilis (Eastern bleeding heart): This classic variety features large, arching stems with pink or white heart-shaped flowers. It is hardy in USDA zones 3-9 and is well-suited for overwintering in colder climates.
  • Dicentra formosa (Western bleeding heart): Known for its compact size and bright pink flowers, this variety is hardy in zones 3-9. It prefers shaded, moist environments and is excellent for overwintering in cooler regions.
  • Dicentra eximia (Fringed bleeding heart): With its delicate, fringed flowers, this variety is hardy in zones 3-8. It tolerates colder temperatures and is suitable for overwintering in various climates.

Tips for Overwintering Bleeding Hearts

Proper care and preparation are essential for successfully overwintering bleeding hearts. Here are some tips to help your plants survive the cold months:

  • Mulch generously: Apply a thick layer of mulch around the base of the plant to insulate the roots and prevent freezing.
  • Cut back in fall: After the foliage dies back naturally, cut the stems to ground level to reduce disease risk and prepare the plant for dormancy.
  • Provide protection in harsh winters: In extremely cold regions, consider covering the plant with burlap or straw for extra insulation.
  • Plant in well-draining soil: Good drainage prevents root rot during the wet winter months.

Regional Considerations

The hardiness of bleeding heart varieties varies depending on your climate zone. Gardeners in USDA zones 3-5 often find that Dicentra spectabilis and Dicentra eximia thrive with minimal protection. In zones 6-9, most varieties will overwinter successfully with basic mulching. In colder zones, additional protection may be necessary to ensure survival.

Zone-specific Tips

  • Zones 3-4: Use deep mulch and consider lifting and overwintering potted plants indoors.
  • Zones 5-6: Mulch well and avoid pruning until spring.
  • Zones 7-9: Minimal protection needed; focus on soil drainage and shade.

Conclusion

Choosing the right bleeding heart variety and providing proper winter protection can ensure these beautiful plants return each year. By understanding their hardiness and regional needs, gardeners can enjoy the delicate charm of bleeding hearts throughout the seasons.
