@kabby It really is an interesting vine with the flowers and pods ... only negative is the seeds are poisonous so if you have small children/grandchildren or pets who like to eat stuff, be aware.
If I ever grow it again it will have to be outside the fenced yard because we have a Golden Retriever who eats everything he can put in his mouth! I thought he'd outgrow that phase but he's almost 3 and still likes to eat everything.
