How to Grow

Cultivation

Grow in fertile, moist but well-drained soil in full sun or partial shade. See aquilegia cultivation

Propagation

Propagate by seed; home-saved seed may not come true. Established plants can also be propagated by division in spring, but they dislike root disturbance and will be slow to recover

Suggested planting locations and garden types

Cottage and informal garden
Gravel garden
Patio and container plants
Rock garden
Wildlife gardens
Cut flowers
Flower borders and beds

Pruning

To encourage more flowers (and prevent self-seeding) deadhead regularly. Cut back foliage after flowering to promote fresh growth in late summer

Pests

May be susceptible to aphids, caterpillars, leaf miners, aquilegia gall midge and aquilegia sawfly

Diseases

May be susceptible to powdery mildews and aquilegia downy mildew
