Aquilegia

This aquilegia is the most vigorous one in the garden and is growing right where it impedes the traffic to and from the shed door. I'm not that fond of the flower shape, but the colour is good and I haven't got the heart to root it out. I'm forever weeding aquilegias out of the borders, where they can very soon get thuggish if not controlled, but this one is just a minor nuisance, so gets to stay. Some aquilegias I do like, especially the ones with long, elegant flower trumpets, but of course they're not the ones that seed themselves around so prolifically. The only ones we planted deliberately, William Guinness, have almost all failed this year. Perhaps it was too cold in the winter.
