I think there are varieties that fruit in higher heat area’s like Brad’s but those may not be singled out for those attributes yet. In mild Nor Cal weather they are planted as ornamental hedge , 50%+ of people have no idea they fruit. There are 100’s if not thousands of tree’s planted in sidewalk strips across town. Some bushes get 25 feet tall and wide , you can hedge them or shape them how you want.
It’s a delicious fruit that when perfectly ripe will have a little give in the middle, like a peach or close to it.
Sweet , tropical flavors, the inside should be juicy pulp , not dry at all. A slight red tint can accompany the pulp like a finger lime caviar’s at the ripest part of harvest. Though tolerable of drought and many conditions, probably not a good fruit to grow in the desert.
