The illustrated growing guide
Columbine
Aquilegia canadensis
Family Ranunculaceae
Est. zones 3-8

Individual plants live 3-4 years but the self-sown seedlings keep the patch immortal — and they cross into surprise colors. The native red one is synchronized with hummingbird migration.
☤ Juglone-sensitiveColumbine is sensitive to juglone — the toxin exuded by black walnut, butternut, and their relatives. Keep it 50+ ft from any walnut or hickory, or its leaves will yellow, wilt, and die back for no obvious reason.
