This is a common landscaping plant in Phoenix. Most people don’t know that the fruit is edible. The fruit has a high latex content so be careful if you have a latex allergy. This is mostly here for trivia. The ones I’ve tasted are not particularly good.

Can be propagated from seed or cutting.

Maybe there are improved selections? https://tropicalfruitforum.com/index.php?topic=56383.msg570054#msg570054
