Last week I was working at a new client's place and I noticed a bunch of little seedling things coming up that just from the leaves looked a lot like trumpet vine. Most of them were no more than 5' tall or so, and had compound leaves just like trumpet vine. Then... I took a closer look and that 30' tall oak tree turned out to not be an oak tree at all but... it had those same compound leaves as all those little things I had been cutting that had leaves (almost?) identical to trumpet vine. What's up? Is this some kind of tree that I've never heard about? Or does trumpet vine do that? Or is it something else? A mutation caused by radioactivity from the flying saucer that's been parking in the guy's back yard?
