Hi, I have a spiny ivy shaped weed growing in my backyard garden in Beltsville, MD. I've had it for a few years now. It is small now but over the course of the next few months it will grow much longer and ensnare itself with all the flowers in my garden and strangle them. It gets an equal amount of sun and shade throughout the day. I can't think of anything else I can tell you. Can you identify it for me and tell me how to get rid of it.
