HH Plant Nursery says:
“Although the White Sapote tree originated in Mexico and Central America, adventuresome Southern California gardeners have successfully grown it since the early part of this century. It does particularly well in our coastal valleys. The custard-like flesh of the yellowish-green, apple-shaped fruit is ultrasweet; the flavor has been described as a combination of banana and very sweet peach.
Suebelle’ is a classic white sapote that has been grown in Southern California for more than 50 years. It produces smooth, round, light-yellow fruit that weighs between three and six ounces. In many climatic zones ‘Suebelle’ bears fruit nearly all year round, and the flavor is excellent.”
