Abbey Road Masterwort

@ Jeremy; Thank you so much, I've been wondering about this for a while!

I'm fairly confident that this is a cultivated astrantia.

The first thing that popped into my head was some kind of passion flower. Just a thought.

I know, I saw the white ones too.... they're completely unique

I think I spotted same sp. but in white: http://www.projectnoah.org/spottings/699...
no idea what it could be...
