 It is a beautiful tree that gets great green foliage and the fruit which this tree is famous for - the custard apples, which are not related to the common apples of commerce.   These beautiful plants are hardy to USDA zone 10, possibly colder, and they grow best in full sun to part shade.  They would make excellent additions to your rare plant collection, or just make a unique statement in your yard.

HAPPY GARDENING :)
