Columbine
Columbine, Aquilegia spp. are a shady favorite. Few flowers signal spring quite so singularly as columbines. Their nodding flowers and spacious foliage look light and graceful wherever you plant them. Hummingbirds are regular visitors to the flowers.
Growing
Columbines grow best in partial shade or light shade. They prefer soil that is fertile, moist and well drained, but adapt well to most soil conditions. Do not overwater.
Division is not required but can be done to propagate desirable plants. The divided plants may take a while to recover because columbines dislike having their roots disturbed.
Tips
Use columbines in well-drained shade gardens, formal or casual borders and naturalized or woodland gardens. Most of the large-flowered hybrids are not well-suited to Texas heat and soils.
