I don't know the varieties as all of them are seed grown from store bought each time I encountered a delicious fruit thru out the years. I only plant the seed from best tasty variety that I ate. I had several varieties that are not good and I don't even bother to grow them as they would be a waste of time,resources. Most of them are 7-8yrs old tree from seeds now and 5 trees actually bear pretty good tasty fruits. There was one tree about 2-3yrs old, and it's gave 5 small fruit, about the size of a teenage girl's fist ( i can't blame the tree for the small fruit since it's about 2ft tall and has about 5-6 fruits on it), it has few seeds, sweet,acidic, and texture is not sandy or mushy. Mom and sister-in-law gave it 5 thumbs up.

invest in a cheap greenhouse and start growing cherimoya yourself. That is just crazy for that price. All of my cherimoya tree do not get any special care or fertilizers. No chemicals. All it gets are compost and mulch. and sun + H2O.
