I found this growing wild here in Kentucky and brought home the seeds for my garden. It grows freely and self sows. I love it mixed in with my other columbines.
And I am putting in an area for native plants so I will add it to that area also.

This is a native to this area. I collected seeds from the wild yard of my mom, sowed them outdoors in the fall and had babies coming up in the spring. That was 10 years ago and they still are here. They freely self sow if not dead-headed.

Since this plant is native from Alaska to northern California, Montana, and Utah, I just planted it and let nature do the rest. It's now blooming for the first time, and it's flowers are, indeed, small. Very pretty, though, and one of the easiest plants to grow in my yard.

I'm going to follow the Sunset book's recommendations and allow it to set seeds so the birds can enjoy some of them. I hope the rest of them will self sow and spread out, too.

I have had good germination and am just starting with them. I'm wondering how moist I should keep them in the garden. Here in the wild(British Columbia interior) they seem to like it pretty wet.

Aquilegia formosa grows in Alaska along roadsides and in woodland clearings. It adapts very well to the garden and self-sows readily. The flowers are rather small, but the colors are brilliant and showy. Lately I have noticed some larger blooms on plants that seem to have crossed with my domestics.
