How to Grow Aquilegia
Aquilegia vulgaris
Columbine (Aquilegia) thrives in partial shade to dappled sunlight and prefers moist, well-drained soil enriched with organic matter. Sow seeds indoors in late winter after 3-4 weeks of cold stratification, surface-sowing as they need light to germinate. Water regularly while establishing but avoid waterlogging, and apply a light balanced feed at planting time only. Plants flower reliably in their first year and self-seed freely; cut back foliage after flowering to encourage fresh basal growth.
When to Start
Direct sow outdoors as soon as soil reaches 8°C — typically early to mid spring. Can also be started indoors 8 weeks earlier for a head start.

Care Essentials
- Light feed with a balanced fertiliser when planting out. Aquilegia are not heavy feeders and self-seed freely without supplemental nutrition.
- Aquilegia flower reliably in their first year from an early indoor sowing with cold stratification. They self-seed prolifically — seedlings will appear around parent plants the following year. The seasonal option lets you track the first grow cycle from seed to flower. Cut back foliage after flowering to encourage fresh basal growth.
