Cat’s Claw Vine, a New Austin Invader

I was on a local property in central Austin this summer, when I was introduced to a new invader to our town. At first I had no way to identify this vine. No one knew about it, and there were no seedpods or flowers to help identify it. Local inquiries amongst my peers led me nowhere, so I […]
