Growing Columbines

Posted On April 3, 2020

The perennial columbine (Aquilegia) blooms from mid-spring to early summer.

Columbines, also known as Granny’s Bonnet, are known for their bell-shaped, spurred flowers, which range in color from light pastels to bright reds, yellows, oranges, purples, and bi-colors. There are over 70 species!

The leaves have a lacy appearance. While they look delicate, columbine are very hardy and resilient—being deer-resistant and drought-tolerant.

The flowers are very attractive to butterflies, bees, moths, and hummingbirds!

Sow columbine seeds directly into the ground in the spring. Allow the plant to self-seed and it will produce many volunteer seedlings!

Planting

Columbines grow in sun or light shade.
Sow seeds indoors 6 to 8 weeks before the last expected frost or direct sow into prepared beds with rich, well-drained soil after the last spring frost.
Press the flower seed into the soil, but do not cover with soil.
Thin to the strongest plants.
If planting a container plant, dig a hole twice the diameter of the pot the plant is in.
Place the plant in the hole so the top of the root ball is level with the soil surface.
Fill in around the plant and firm the soil gently.
Space mature plants 1 to 2 feet apart, depending on the variety.
Water thoroughly.

Care

Do not overwater.
Deadhead faded flowers and new buds will develop along the stems. The bloom season can be extended by as long as six weeks into mid summer.
Cut back foliage to the ground in the fall.
When the ground is frozen, mulch to protect plants

Pests/Diseases

Powdery mildew
Leaf miner
