American persimmon and other fruit trees from Chestnut Hill Nursery?

Local big box store carried selections of fruit trees from Chestnut Hill, including American persimmon, American Chestnut and mulberry. I snapped this picture in spring and the calyx on immature persimmon fruit was already quite large. Does it mean this variety of American persimmon will have bigger fruits? My local wild trees have tiny fruits with proportionally small calyx on them. Has anyone tried fruit trees from this nursery? They are mainly for drawing in deers for hunting, not for human consumption.
