Overview
Aquilegia (Aquilegia spp.), commonly called Columbine, produces distinctive spurred blooms in spring and early summer. The Kirigami Mix offers compact plants with upward-facing flowers in a wide range of colors. Short-lived as a perennial but prolific self-seeder, so colonies naturalize easily.
Sun & Exposure
- Ideal: Part shade to full sun
- Best performance: Morning sun with afternoon shade, especially in hot climates
- Avoid: Intense afternoon sun in summer, which causes early dormancy
Watering
Columbine prefers consistently moist soil but tolerates brief dry spells once established.
- Water regularly during spring bloom; reduce after foliage dies back in summer
- Avoid waterlogged soil — good drainage is essential
- Established plants are moderately drought tolerant
Soil & Planting
- Well-draining, average to humus-rich soil
- Plant in spring or fall; space 12–18 inches apart
- Shallow roots — avoid deep cultivation around plants
Fertilizing
Light feeding produces the best blooms without excessive foliage.
- Apply a balanced slow-release fertilizer in early spring
- Avoid high-nitrogen fertilizers, which favor leaves over flowers
Pruning & Deadheading
- Deadhead spent blooms to extend flowering and prevent excessive self-seeding
- Allow some seed heads to mature if you want plants to naturalize
- Cut foliage back to the ground after it yellows in late summer
Winter Care
Hardy in zones 3–9. No special winter protection needed. Self-sown seedlings will emerge the following spring.
Common Issues
Problem
Leaf miners (white tunnels in leaves)
Cause
Leaf miner larvae — cosmetic only, not fatal
Problem
Powdery mildew
Cause
Poor air circulation or dry soil
Problem
Short lifespan
Cause
Normal — individual plants live 2–3 years; let self-seed
Tips
- Excellent cut flower — harvest when buds are just opening
- Hummingbirds are drawn to the long spurs
- Goes dormant in summer heat; interplant with later-emerging perennials to fill the gap
