Actually, it is zoned for 450 chill hours.
I have had a FloridaKing in the past though, which is zoned for the same amount of hours, and it did fine making a good amount of peaches.
Seeing as I have an extremely small yard, I want a large peach that makes a profuse amount. I cannot stand small peaches and even "medium" ones are terribly frustrating. The FloridaKing was "medium" and many times not even worth picking.
Many peach types claim to be "large" but Tasty Giant claims to be over a pound, most of the time.
