Columbine

General Information

Columbine is an easy-to-grow, upright, clump-forming herbaceous perennial.

Columbine is typically found in rocky woods, slopes, ledges and open areas. Columbine prefers partial shade conditions, especially in the south, but will tolerate more sun with adequate moisture. As a woodland wildflower prefers organically rich, moist soil.

Columbine has showy red and yellow tubular flowers that last up to one month. It blooms between March and May and makes a good cut flower. Deadheading encourages additional blooming.

Columbine can naturalize to form large colonies in optimum growing conditions.

Culture Information:

The best locations to plant Columbine include woodland habitats, naturalized areas, butterfly gardens, hummingbird gardens, shady garden borders, native gardens, pollinator gardens, cottage gardens, and rock gardens. It also does well along walkways.

When first planted, Columbine should be watered weekly for first few months, unless at least an inch of rain has been received in the last week to help it get established. After it becomes established, Columbine does not require regular watering, HOWEVER, continuing to water after bloom will extend the foliage period. In dry locations, the plant will otherwise go dormant.

As with most perennials, Columbine can be cut to the ground after foliage browns. Deadheading is the best management strategy to control its spread. Columbine freely self-seeds and can create a nice groundcover.

Tolerates:

Deer
Rabbit
Drought
Dry Soil

Pests & Disease:

Columbine has very good resistance to leaf miner, which often causes severe damage to the foliage of many other columbine species and hybrids.

Tall Thimbleweed doesn’t usually have serious disease problems.
