Linda, honestly, any of the natives will do, but I'd just need to be a little more careful where I would plant some of them. Specifically I'm looking for Swan Flower (Aristolochia erecta) but any of the others would work too.
Texas Snakeroot (Aristolochia serpentaria)
Texas Pipevine (Aristolochia coryi)
Woolly Pipevine (Aristolochia tomentosa)
