Growing Notes
Part sun to shade in moist, humus-rich ground. Give it afternoon shade in harsh climates; full exposure burns the foliage and shortens the season. Space about 15 inches apart. It is happiest where the soil does not dry out completely.

Soil: Moist, well-drained; humus-rich

Maintenance
Let it self-sow to keep the planting going, since plants are short-lived. Note that columbines cross freely with each other, so seedlings near another columbine will not come true to color. If you want to maintain separate colors, it’s best to plant separately. Or, if crossing is desired, plant closer together and observe new seedlings with varying color combinations and petal counts. Shear tired foliage in midsummer for a fresh flush. Leaf-miner squiggles are cosmetic.
