They are in season now! I have seen them in Kroger stores and Farm Fresh too. However, I have only seen the large ones. My friend in MO. says you need the little ones (sbout the size of a large or small cherry tomato). I would check you local Whole Foods or HFS. Also, search to see if you have any orchards or local farms nearby. They may have trees.

Here's the recipe

:
Grandmother Trexler's Persimmon Pudding
2 cups persimmons
3 eggs
1 3/4 cup milk
2 cups flour
1/2 teaspooon baking soda
1 teaspoon salt
1/2 teaspoon cinnamon
1/2 teaspoon nutmeg
1 1/4 cup sugar
1/4 cup grated coconut
1/2 stick butter or margarine
Put dry ingredients in mixing bowl. Add eggs, milk,
and melted butter, mixing as you add them. Finally
add persimmons. Bake at moderate temperature (350
degrees, plus or minus, depending on your oven) about
1 hour. (PS I suggest watching it carefully from
about the 50 minutes time in the oven and baking it
until it is beginning to brown, even if this takes
more than an hour.)
