I am growing from seed from europe, china and USA but no sprouted. But I am growing too from fresh fruit from South Korea, Spain and New Zealand. From Spain and New Zealand are seedless but from South Korea some had sprout.
I am growing them in lowland ultra tropical in equator. So they grow not suitable for my climate. But some peach and some plum had grow vigorously even beat some my tropical fruit. The peach had flower 2/3 year from seeds.
I am growing too some local variety that had seedless and astringent. They grow not suitable too for my climate. They never tall, always regrow from rootsucker.
That's my experience grow persimmon in equator. My dream is to hybrid them with black sapote, ebony and mabolo velver.
