Columbine grows best in full sun and well-drained, fertile soil. For most climates, columbine grows best in partial shade; however, in warmer climates like Florida and Southern California, less sun and more shade is preferred.
Plant in spring, spacing plants 1 to 3 feet apart, depending on the variety. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Dig a hole twice the diameter of the pot the plant is in. Carefully remove the plant from its container and place it in the hole so the top of the root ball is level with the soil surface. Carefully fill in around the root ball and firm the soil gently. Water thoroughly.
Columbine is prone to a fungal disease called powdery mildew. The spores spread through splashing water and travel on wind currents to infect other plants. Once established, powdery mildew is difficult to control. Most fungal diseases develop during rainy, wet weather, but powdery mildew develops when daytime temperatures are warm and nights are cool. The disease is not dependent on water on the leaves. You can help your columbines resist the disease by cutting back the affected plant parts (down to ground level if necessary), providing afternoon sunshine, and lots of air circulation in and around the plants.
One of the most common pest on columbine is leaf miner. These fly larvae feed inside the leaf. You’ll see their damage as light-colored, winding tunnels on the leaf surfaces. Cut off and destroy all infested foliage after plants have bloomed; the new leaves that regrow later in the season will be miner-free.
Phlox – Purplish-blue woodland phlox makes a perfect companion for columbine in a shady border. Both appreciate light to moderate shade and bloom mid- to late spring.
Toad lily – Toad lily takes up the slack in the shady border after columbine finishes its springtime show. Its orchid-like blooms grace the fall garden.
Foamflower – The frothy flower spikes of foamflower look great paired with the bluish-green foliage of columbine. Because it is a low grower, place foamflower in front of the columbine.
