I have a friend that claims Virginia Creeper is also known as Boston Ivy and is highly desirable, especially if creeping up a tree and his brick house. My gardener instincts and training tell me he's wrong!! What do you think? I love English ivy but here in west Texas it's allowed to grow rampant in the gardens and becomes a bully.
You've asked an interesting question, one I had never considered. Virginia creeper Parthenocissus quinquefolia and Boston ivy Parthenocissus tricuspidata are, let's say, cousins. They are not the same, but come from the same family.
There is a difference in their looks, too, Boston ivy has a trifoliate leaf, meaning it is a whole but has three sections, much like a maple leaf. Virginia creeper has a leaf that has separate parts, not whole. Hard to describe without a photo, and I don't have one handy to send, but you probably could google it or find it in plant files.
Another little difference, if I remember correctly is that VC leaves are reddish when young, then become green. Boston ivy is always a dark green. VC might also grow a little longer in its vining. I have no experience with it, but have heard that Virginia creeper can choke trees, too.
I hope this helps, I haven't had much experience with either, but am vaguely familiar with both.
