Southern California is an arid desert , Rollinia prefer 100% humidity, ton’s of water and temps not going below 50 degree’s.
This in a nutshell is what limits plenty of tropical fruits in So Cal.
South Florida is high humidity and rains all summer.
Comparing 10b CA, and 10b FL are apples and oranges.
I just saw 3 huge Soncoya tree’s in FL and they will never fruit because hand pollination is necessary.
Same with lots of Annona.
