Proboscidea parviflor also known as Devil's Claw or Unicorn Plant is a wildflower or weed (depending on one's viewpoint) whose immature pods can take the place of okra in recipes and whose rip pods can be used in basket making and other crafts. The seeds are also edible -- they are better to eat when young, before they develop a hard coat.
The ones growing on my land have attractive pink & white trumpet-shaped flowers. In a severe drought, such as the one we have just been through here in central Texas, they go semi-dormant and renew themselves with the coming of rain.
