Hopefully Noel will chime in about his tree and include some pics. I was at his house last weekend and he has a really nice looking tree that I think is over 10 years old he said. He bought it grafted from Excalibur and it has not fruited yet. I think he said it was getting ready to flower soon.
Starapple, or caimito, is an excellent fruit. In my opinion it's superior to abiu, not just in taste but also in the fact that no fruit flies sting them. Also they are a much more attractive fruit inside in color and shape than abiu. Here every single abiu is stung by oriental fruit fly unless you go through extra work of bagging every fruit or spraying, neither of which i do. The starapple has a thick enough rind that fruit flies cannot penetrate. The flavor is reminiscent of milk shake. In fact in Vietnam they call the fruit something like Mother's milk, or breast milk. Latex next to skin not a problem if you know how to eat it. You cut crosswise and spoon out, not eating parts very close to exterior skin.
I'm o f the opinion that i have the best and largest cultivar of starapple. I posted photos before but here goes again. Haitian on left and mine on right. As you can see it is way larger than Haitian cultivar:. (Really don't think Haitian is a good cultivar.)
I have not named it yet or registered yet. I'm willing to sell budwood to anyone interested. This tree does get large, but with pruning could be controlled to small size. My trees started fruiting from seed in about 5 years. They fruit abundantly always in beginning of Spring, so i'm eating them right now! I have a couple of grafted cultivars of green types but don't recommend them as here they get easily mold growing on the fruit. They are much thinner skinned and crack easily in our rainy environment. Might be good in Florida though? These green cultivars seem to stay a bit smaller than the purple.
