I found some something interesting about growing regular cherry in subtropical climate:
"Cherry is (Prunus avium L.) known as a high chilling requiring species, suitable to continental climates. However, scientists and growers are recently looking for the opportunities of growing cherries at subtropical and tropical areas. For this aim, studies were carried out at the University of Cukurova, Department of Horticulture, since 1990. In the experiments, besides the performances of cherry cultivars, chilling requirements were also calculated. Cristobalina, Temprano de Sot, Precoce de Bernard, Sunburst, Lapins, Chelan and Na-1 are the promising cherry cultivars, suitable to subtropical conditions."
That's all the info I could get. I cannot access the full document "CHERRY (PRUNUS AVIUM L.) GROWING UNDER SUBTROPICAL CONDITIONS" by A.B. Küden and A. Küden
