I couldn't find a site that has pics and names but there are quite a few pictured in the Gallery on this forum that may help you. There is also a forum called, "Name That Plant" on Gardenweb where people who are more knowledgeable than some of us try to tell us what we have. The are usually right on the money. You may try there.
Take some pictures of your mystery plants and post them for us. There are so many people on here that really know their stuff. They'll help you narrow it down.
