Aquilegia caerulea ‘Snow Queen’ – White Columbine

The White Columbine ‘Snow Queen’ (Aquilegia caerulea ‘Snow Queen’) is a graceful and light variety of columbine, appreciated for its pure white flowers, elegant habit, and hardiness.

Origins and Characteristics

Native to the mountainous regions of North America, Aquilegia caerulea is an alpine species that has given rise to several cultivars, including the ‘Snow Queen’. This variety stands out with its white flowers, sometimes slightly cream-colored, giving it a delicate and refined appearance.

Short-lived perennial (3 to 4 years), it self-seeds spontaneously, allowing it to reappear in the garden year after year.

Planting

Young plants in pots should be planted in spring or autumn. Space the plants 30 to 40 cm apart to allow for good development. Enrich the soil with well-rotted compost if needed.

Watering

• Regular watering after planting to promote rooting
• Tolerates some drought once established
• Mulch around the base to retain moisture in summer

Pruning

• Remove faded flowers to encourage reblooming
• Cut back dead parts at the end of the season

Tips for Beautiful Blooming

• Well-drained soil + gentle exposure = optimal blooming
