Aquilegia species and hybrids

Crop Rotation Group

Miscellaneous ●

Soil

Fertile, well-drained soil enriched with compost, with a neutral to slightly acidic pH.

Position

Partial shade.

Frost tolerant

Yes, aquilegia is a hardy perennial. Well-rooted plants are hardy to -34°C (-30°F).

Feeding

Mulch over the plants’ root zones with rich compost just as the new growth emerges in spring.

Spacing

Single Plants: 30cm (11") each way (minimum)
Rows: 30cm (11") with 30cm (11") row gap (minimum)

Sow and Plant

Bare-root or potted plants of improved varieties and wild species are available or you can start seeds indoors in late winter. At room temperature, seeds germinate in 15 to 20 days. Set out plants or seedlings as early as possible, while the soil is still cool. Plants may not bloom their first year after planting. Young plants need water when they are actively growing. A surface mulch suppresses weeds while making the plants look more attractive.

Notes

Large-flowered hybrids made stunning additions to the formal flower garden. Columbines develop fleshy roots that serve them well for a few years, and then individual plants unexpectedly die. In hospitable situations the plants reseed themselves, so the loss of older plants goes unnoticed. Columbines are non-preferred by rabbits.

Harvesting

Gather stems for use in cut arrangements as you need them. It is normal for columbines to bloom for a month or so and then start dying back.
