That is an ivy geranium, don't remember the name I'll go look in my green house later and see if I saved the tag :-o I LOVE THIS GERANIUM!!! This is one of them that I wintered in my office windows at work. Isn't it a beaut?
Netty, I think you are correct. the flower is a geranium, I agree an ivy one, and the foliage is lobelia, most likely a combination pot of some kind. I grew both in combination hanging baskets/pots this year, (but not that variety of geranium.)
