Happibun's Hardy and Persistent Columbine
Aquilegia

I can not say for sure whether I first sowed aquilegia seeds in to the front or back garden, but these plants have been coming back again and again for as long as I can remember.

The ones out front tend to have medium to large single flowers. Originally they were all white, but now some of them are a delicate pink with green tips, and one plant is all dark purple.
