I don't know of anyone's having enough success with Annona cherimola in Florida to be able to recommend it. I have been given a one gallon plant of 'Dream' and will wait and see what it does. The leaves of 'Dream' appear to be atemoya, i.e. 1/2 cherimoya, 1/2 sugar-apple. I have not seen the flower or fruit.
During my years of Annona hybridizing at Zill High Performance Plants, here in eastern Palm Beach County, I worked with 8 or 9 varieties of cherimoya that Gary Zill bought at nurseries in California. Most never produced a properly-ripened fruit for eating purposes, though we often got viable seeds from them for our breeding program. The variety called 'Spain' had a few decent-tasting fruits on it some years, and none other years. These varieties were all growing in 45-gallon or larger containers, well-drained, with drip irrigation, frequent spraying against potato leafhoppers and fungi, and plenty of fertilizer. I have not worked with cherimoya selections made since the 1980's, so, for example, I have not worked with 'Fino-de-Jete.'
