A friend of mine found a box of old seeds in his parents' root cellar at their old house in Asheboro, NC, before the house was torn down.
He sent me a bunch of white "vining" okra, not the Clemson green okra that most people grow. I went over to the co-op and was talking to some of the old timers one day, and they said they'd heard of it from their elders but never seen.
It's a beautiful plant with huge 5-6 inch pods that are tender.
