This depends somewhat on your location. In cooler regions, you can plant or place your Columbine flowers in a location where they will receive full sun. However, in warmer climates where the sun is more intense, this plant prefers partial shade. If you live in a warmer southern region, plant or place your Columbine in a location where it will receive full sun in the morning but be shaded in the afternoon when the sun is at its hottest.
