My mother can id just about any plant in the yard even if it's just an inch tall, but she's not great at growing those plants... me I'm the grower... can barely id my kids!!! LOL!! Hope someone can help me out, I want to know whether to keep this plant growing on my fence or make room for something else. It is a cane type plant, has thorns, was wondering if it was some sort of wild fruit? I think the last pic is a baby from the main cane. I'm enclosing pics and I'll be extremely happy if someone can id this for me!! Thanks bunches :)
