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!
- 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.
- 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
- Powdery mildew
- Leaf miner
