There are many different cultivars of jocote. In El Salvador, there are 2 classes -- winter and summer -- depending on when they bear and whether they are adapted to high- or low- lands. The have names such as azucaron, corona (my favorite), iguana, pitarillo, etc. Extremely popular in Central America, where they are eaten fresh or with in a green / sour state with salt.
My favorite of the ones that are commonly grown in FL is the large yellow one (not the ambarella), which have a large seed but a very delicious sweet flavor with a hint of acidity. Sheehan really liked this one too. I have no idea what the cultivar name is.
They are generally easy to grow, but they do consume a lot of yard space. They are perhaps the most violently growing tree that I have seen. Mine can easily put on 10 - 15 feet in a single summer. They also tend to be poorly rooted and will fall over in a good storm. So, it's a tree that you will want to grow on the south side of a canal -- away from the house and where it won't shade out other trees.
