So many pretty varieties of this lovely spring flower. I add a new one every year here and there, sometimes replacing ones that are less energetic. I also get lots of volunteers, usually not true to form, but I let them bloom before pulling them out.

Positive Gabrielle On Jan 15, 2006, Gabrielle from Washington, IL (Zone 5a) wrote:

This is one of my favorite Columbines. There are so many color combinations and large blooms. Each one I see is my favorite until I see the next!

Stratification and light aid germination of seeds.

Blooms mid May to late June in my garden.

McKana's have been reliable performers in my gardens. I have three plants that are well-over 8 years old, and they bloom profusely from June through August. They reach 48" tall, and usually require some staking as they fill with blooms.

This plant has been a true performer in my gardens for 5 years through drought and drown. Doesn't seem to matter to it.


Editor's Note

Aquilegia is regarded as dangerous, in particular the seeds and roots. However, their acrid flavor generally helps to avoids poisonings.

The flowers of various species of Aquilegia were noted as historically being consumed with other fresh greens, and are reported to be very sweet, and safe if consumed in small quantities. The plant's seeds and roots are highly poisonous however, and contain cardiogenic toxins which cause both severe gastroenteritis and heart palpitations if consumed as food. However, this plant is better avoided due to its high toxicity; columbine poisonings may be fatal.

We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to warn gardeners, parents, and pet owners to look further for more information.

I have been growing this plant for 2 years and find it very successful in its second year. It has been flowering for over two months (I have been dead-heading it), and is a combination of crisp white outer petals, and cream-coloured inner petals.

I too love this plant and was happy to see that someone else found better blooming with deadheading. Everyone told me it wasn't needed, so I didn't do it this Spring--guess what, no more blooms! Last year they went from Late March thru June with religious deadheading.

Charming plants with light, airy foliage and profuse flowers. Will flower all summer if dead-headed. Self-seeds fairly easily. Can grow to 4 ft with a spread of 3 ft.

Frequently bi-coloured eg lavender and cream, pink and white, yellow and cream, etc. Plants in my garden are currently seven years old. Shorter varieties can be short-lived.

Neutral Sis On Aug 31, 2001, Sis wrote:

Hybrid columbines may be short-lived even under the best garden conditions. They generally live 2-4 yrs. Plants self-sow prolifically and new plants are always developing (but seedlings may not be true to parent.) Plant in humusy and well-drained soil.

Sow seed outdoors in spring or summer, or sow indoors in winter after dry storing them in a refrigerator for 4-6
weeks. Plants develop quickly.

Leafminers create pale tunnels and blotches in the leaves. Remove and destroy damaged foliage. In severe cases spray weekly with insecticidal soap. Borers also attack columbines, causing the plant to collapse dramatically. Remove and destroy all portions of affected plants.
