Corsican Columbine Plant Care

Corsican Columbine (Aquilegia cossoniana) belongs to the Ranunculaceae family within the Aquilegia genus. Corsican Columbine is native to the Atlas Mountains in northwestern Africa.

Corsican Columbine displays an upright, clumping perennial growth habit, reaching up to 2 ft tall with a spread of approximately 1.5 ft. Corsican Columbine produces unique spurred flowers in various colors like blue, purple, pink, yellow.

Leaf size: approximately 4 inches.

Aquilegia cossoniana requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Corsican Columbine thrives in partial shade to full sun.

Aquilegia cossoniana grows best at temperatures of 50–75°F. Corsican Columbine prefers humidity levels of 40–60%.

Moist, well-draining soil with high organic content. Good drainage is essential for Corsican Columbine to prevent waterlogging, which leads to root rot and fungal issues.

Feed Corsican Columbine every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Divide clumps every 3-4 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Corsican Columbine can be propagated through seeds. Similar propagation techniques also apply to amalia's columbine plant care, which shares the same genus.
