RE: ?? about planting Persimmon trees
As Ross said a variety is grafted onto a rootstock (usually a Persimmon seedling). Nurseries usually grow the grafted trees for 1-2 years after grafting and the scion wood that was grafted was from bearing wood, so the tree will give fruit quicker than planting a seedling. The variety that I've had the best success with is "Early Golden". Some varieties of Persimmon will give male and female flowers. But; you could have a male variety grafted onto the tree as Ross said.
