I'm almost certain this is a form of Geranium à oxonianum... there are so many varieties.

As for light, I would lean toward more sun, although it looks like it's doing well where it is!

Thanks! I don't care about getting the variety exactly right -- it is fun to know the full name but mostly I want to know how much light it gets.

Mine isn't as neat and tidy as some -- it seems to be going all over -- but it is definitely healthy, so I can't complain. :)

I agree with coolplantsguy that it is most likely a form of oxonianum. I believe the easiest to find on the market and most popular one right now is called 'Claridge Druce'. There are so many cultivars being sold, with the only difference being in the colour of the flowers. Many have very slight differences in the shade of pink and are difficult to tell apart. 'Claridge Druce' hails from the UK and has been around for a while.

Thanks! I do agree that it is like Claridge Druce -- so if not that cultivar, then awfully similar.
