Columbine

Calling All Columbines

One of the stars among spring perennials is Aquilegia (pronounced a-kwil-EE-jee-a), also called Columbine. In the southeastern US, there are two common species, the hybrid Aquilegia x hybrida and Aquilegia canadensis, the Wild Columbine or Red Columbine. Less common but more impressive is Aquilegia vulgaris.

All prefer moist woodland soils and partial shade in the South. They will tolerate more sun in cooler zones. They are deciduous perennials in zones 3-8. They may go dormant before winter if soil stays dry. Provide supplemental irrigation in extended dry weather but do not allow soil to be boggy. Columbine foliage is finely cut, almost lacy in appearance, and may have a slight blue tint. The hybrids bloom in pastel shades of rose, blue, pink, yellow, white and bi-colors. Most flowers have long spurs. Aquilegia vulgaris has a two-layer double form without spurs that looks like a tiny Dahlia. Some of these have an ombre color pattern. A somewhat strange common name for these doubles is “Granny’s Bonnet.”

Columbines reach heights of one to three feet. They bloom in early spring, then fade into obscurity. They can be raised from seed, but will not bloom until the second season. They will reseed, but hybrid seedlings will not mimic the mother plant. Removing spent blooms encourages more flowers.

Deer and rabbits leave Columbines alone. Unfortunately, the plants are a frequent target for leaf miners. On a garden tour several years ago, the host proudly displayed her “variegated” Columbines. I didn’t have the heart to tell her that her plants were not variegated at all but had a serious leaf miner infestation. If plants show signs of miner damage, remove the damaged leaves but cutting off the entire stem. The plant will regenerate new leaves.

The native Wild Columbine, Aquilegia canadensis, departs from the pastel colors of their cousins and instead sports colorful red and yellow flowers. It will reseed and, unlike the hybrids, its offspring will have the same flowers. It is not prone to leaf miner damage. Different from the other species, Wild Columbine can be used in rain gardens, where they may be subject to wet conditions for days at a time.

All the Columbines make wonderful additions to shady woodland beds and pollinator gardens, where they are popular with butterflies, bees, and hummingbirds. They look best planted in groups rather than singles.
