I generally don't worry too much about it because seeds produced from cross-pollination are going to produce a plant that is characteristic of one or the other parent, not both. So, you'll get true okra, you just won't know which one until you see the pods. I don't know if I mentioned, but Jade has turned out to be my favorite and can't be beat when the pods are 3-4".
I am going to cut some tree limbs that should make the sun area larger out there. We are excited about the new garden area.
