It looks a lot like Geranium pyrenaicum 'Bill Wallis' which I grew from seed, the flowers can vary a little as some have white centres where others don't. I have photos of some flowers, will have to go out and get photos of leaves. They do have the hanging bunches of flower buds like yours. I haven't taken any photos lately but they are in flower now, it's so dull and freezing cold outside here! I'll see if I can get some decent shots of the leaves to compare.
