I have a very small (1' tall) Texas Persimmon. I'm trying to select a pollinator for it. What will cross pollinate a Texas Persimmon? I live in Mesa, AZ, USDA zone 9, where we enjoy bipolar weather. That's up to 115 degrees through the long summer and and down into the 20's in the short winter. I am not sure if my current tree is a male or a female. Any suggestions?
