European columbine?

I'm pretty sure I figured out what this is: European columbine (Aquilegia vulgaris var. Stellata, possibly 'Blue Barlow'). The leaves are definitely columbinish, but the upside-down flowers are completely different from the native columbine I planted. I assume it was planted deliberately, but I only noticed it a year or so ago. Supposedly it doesn't last more than a few years. It is non-native, but very pretty, so if it self-seeds I will keep it around.
