Mystery Alpine

This plant has appeared in my front border. It is about 4 inches across and is growing in free draining , alkaline soil. Years ago, this was an alpine border.

Any suggestions gratefully received!

 

looks like it could be a aquileiga , see what the others have to say

 

That's not a seedling, so it must have been there last year.

Aquilegia (AKA Columbine or Grannies Bonnets) shoots emerging (to right of centre):



Another one a bit closer

 

Thank you. I've only taken over this garden recently so I'm still trying to work out what everything is and if want to keep it.

 

If you have one you'll probably have loads more.
I've just recommenced my ongoing cull. Last year there were a few that I thought garden worthy so I marked them. Sadly I'm plagued with squirrels and the markers have gone.
