What about a Poison Ivy? I have my trees outside and during a summer or 2 ago I had a female friend ask if my trees are real. well she snatched off a few leaves without asking, (not a friend anymore) but i decided to curb people's need to get a quick feel of my trees. so while I was helping a friend rid them of this pesky vine( I'm immune to them) I decided to give it a go. An I now have a cascade that has a red flush in the fall, and a red flush for all whom touch without asking !!!
