How to grow it:
Casimiroa edulis is one of those exotic subtropical trees which can withstand some frost.
A native of Mexico, it is known there as the white Sapote, and grows in higher altitudes, so is relatively hardy.
I have always wanted to try the fruit but have never grown it because of a lack of space.
A Casimiroa grown from a seedling will reach a height and spread of 20m and tolerates various soil types, but it is better to grow as a grafted tree.
