Growing Columbines

0

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


  • Columbine grows 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
