Growing Columbine in Zone 10A

Columbines are elegant, woodland-edge perennials with distinctive spurred flowers beloved by hummingbirds and long-tongued bumblebees.

Zone 10A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Self-seeds freely and naturalizes; new seedlings often create unexpected color combinations
• Drought-tolerant once established; prefers partial shade in hot climates
• Cut back foliage to ground after flowering — fresh new leaves emerge
• Hummingbirds are primary pollinators of long-spurred species
• Short-lived perennial (3-5 years) but self-seeds to maintain colony
