"One named cultivar, 'Imery', introduced into Florida from El Salvador and grown at the Agricultural Research and Education Center, Homestead, is large and pinkfleshed but not as flavorful as some of the white-fleshed acquisitions from Guatemala."

Do you know background info of your tree, where it is from? I am in Florida, I'd be happy if you grow one that has success here.
