Really, there is a lot of D. virginiana X D. kaki. This cross isnt problem, both species are decidious and subtropical. Usually do it for cold tolerant cultivars.
Maybe we can make hot tolerant Persimmon cultivar, that dont need cold dormancy.
Need to cross D. kaki with some of the tropical Diospyros spp.
Druss,
decandra fruit season just started in Thai and VietNam. You can buy this fresh seeds on Ebay right now.
Can you tell us when the fuit season of Australian Diospyros spp., especially D. australis?
What species are decidious and what are evergreen?
