@IbisFLA. I wrote "Bird of Paradise" when I meant to write "Pride of Barbados" in my answer above.
If you go to the Plant Database, there are a couple of photos of the Pride of Barbados (Caesalpinia pulcherrima) seed pods that have popped and curled.
I usually pick mine off as I'm heading out to run errands, throw them in the car, and forget. The extreme Texas heat dries the pods and they pop all over in the car!
