What is this flowering plant?

Kindly remind me what plant this is, I seem to recall it's some kind of Geranium?

 

I to think it is a Geranium.
However I am not confident to take ID any further as there are so many.
Pics of the flowers might help.

Check out Geranium × oxonianum - it's invasive around here, very prolific.

 

Is it possible that it's Hardy Geranium? (Cranesbill Geranium)

 

Geranium × oxonianum is one of those (there are many others, though).

 

This is a leaf on my Geranium x oxonianum Wargrave Pink.

Cranes bill Geranium is just the common name for a hardy Geranium of which there are many specieas ...including even more named cultivars
Did you look at the link in my post above?
All on that link are Hardy Geraniums.
