Thorny vine ID?
I have this "demon" growning wildly in a brush area & it's wicked. It grows straight up out of the ground up to 4-5 ft without branching off, has thorns, has tubor root, no flowers, & spreads like crazy. I'm sure Roundup will get it, but I want to know what it is! I had it in South Georgia & now have it here in VA. It grows in brush where there's no activity on my part!
