The Helpful Gardener wrote:Japanese cherry trees are not fruiting plants, but Cynthia is correct in lumping them with the fruiting cherries; they are the same genus and share many of the same issues. While ornamental cherries are not easy to start they can be challenging to keep healthy in areas where fungal diseases can be problematic. Florida is likely less prone to such issues, but it is also warmish and Prunus serrulata the true Japanese cherry is listed in Dirr as "Zone 5 to 6, and south depending on the clone" so it may well be impossible unless you find a specific clone that works. I might steer you to Taiwan cherry (P. campanulata), also used in Japanese gardens, very refined, and tolerant of Zone 9 temps. Dirr says "the flowers may be the most handsome of all ornamental cherries." High praise from the high priest of woody ornamentals...
There are some cherry tree grow large and some are compact.
In Japan there over 350 or more named cherry tree. most are white to pink floer, One cherry bloom is avocad color. Since cherry tree bleed lot if pruned, if you have large garden and don't have to controle size, Youshino, Kanzan, Hegan. one compact cherry bloom twice per year, spring and fall. some bloom twice in spring. Since cherry tree cannot import from Japan, we have limited number of variety, dozen or so.
