Aguilegia. Columbine is a hardy perennial with fern-like foliage and graceful flowers that bloom from May to June. Flowers come in a vast array of colors to include: red, yellow, pink, blue, lavender, and white. Columbine grows from 1 to 3 feet in height and makes a wonderful addition to any flower border. It grows best in moist, rich, well-drained soil with light shade. If grown in full sun, provide adequate moisture.
Seeds may be sown outdoors in spring and summer up to 2 months before frost. Indoors, sow and place in refrigerator for 3 weeks and then germinate at 70-75 degrees for 21 to 25 days. Do not cover seeds with soil as light improves germination.
Heirloom seeds are collected, cleaned and packaged by hand at Mount Vernon.
