These are the kind with black, rock-hard seeds from western Texas. I have a few extra coming up in a pot and would like to swap 6 of them for some other member of this family. These plants love hot arid conditions in full sun. They seem to do well in whatever kind of dirt you might have, in a garden or a pot. The flowers are very foul smelling, but very pretty. I can e-mail a picture of flower if interested. These grow fast so I would like to ship soon while they are still small.
