Key Facts

Native to eastern North America
Herbaceous perennial with nodding red and yellow flowers
Attracts hummingbirds and early season pollinators
Blooms in late spring to early summer in many climates
Prefers well drained soil and part shade in hot areas
Often self seeds and can naturalize in suitable sites
Generally grown from seed for reliable results

Wild Red Columbine is a native eastern North American perennial with nodding red and yellow flowers that draw hummingbirds and early season pollinators. It fits well in naturalized borders and woodland edges but will often self seed where conditions suit it.

Identification

Aquilegia canadensis produces nodding red and yellow flowers above a mound of finely divided foliage. Plants commonly reach one to two feet tall and spread about 12 to 18 inches when established. Bloom time is late spring to early summer in many regions.

Where to grow and best uses

Grow Wild Red Columbine in naturalized beds, woodland edges and mixed perennial borders. It tolerates full sun to part shade and does best with some shade in hot climates. The plant prefers well drained soil and tolerates dry to medium moisture, so avoid poorly drained sites.

Hardiness and bloom

This species is hardy in USDA zones 3 to 8. Expect flowering in late spring to early summer, with exact months varying by latitude and elevation.

Planting, spacing and propagation

Plants are generally grown from seed and often self seed in suitable sites. Space plants about 12 to 18 inches apart to allow room for clumps to develop and for seedlings to appear. Division and basal cuttings are possible but can be unreliable, so seed is the most consistent method for home gardeners.

Watering and soil care

Plant in well drained sandy to loam soils. Keep young plants evenly moist while they establish. Poor drainage leads to crown rot and reduced flowering, while established plants tolerate drier soil.

After flowering and controlling spread

Deadhead spent blooms to limit self seeding, or leave seedheads if you want the plant to naturalize. In colder parts of its range plants die back to the crown in winter and regrow in spring.

Frequently asked questions

How fast does Wild Red Columbine grow?: The plant typically reaches its mature size of one to two feet tall with a spread of about 12 to 18 inches. Growth rate varies by site and propagation method, and plants commonly fill a spot over several seasons as they self seed.
Does Wild Red Columbine attract pollinators?: Yes. The nodding red flowers attract hummingbirds and early season pollinators.
Will it naturalize or become invasive?: It often self seeds and can naturalize in suitable sites. It is not widely reported as aggressively invasive, but seedlings can appear where seed is allowed to drop.
Can I divide existing clumps?: Division is possible but sometimes difficult. Many gardeners propagate by seed for more reliable results.
