Understanding Frost Resistance in Columbines

Frost resistance refers to a plant’s ability to survive and flourish despite low temperatures. Different columbine varieties have varying levels of frost tolerance, influenced by their genetic traits and native environments.

  • Growth Habit: Consider compact or spreading types based on your garden space.

Several columbine varieties are known for their frost tolerance. Here are some popular options:

  • Aquilegia vulgaris: The common European columbine, hardy and adaptable.
  • Aquilegia chrysantha: A native North American species with bright yellow flowers.
  • Aquilegia caerulea: Known for its striking blue blooms and cold hardiness.
  • Hybrid varieties: Many cultivated hybrids are bred for increased frost resistance.
