Annona squamosa

Annona squamosa is a small, well-branched tree or shrub from the family Annonaceae that bears edible fruits called sugar apples, sweetsops or custard apples. It tolerates a tropical lowland climate better than its relatives Annona reticulata and Annona cherimola, and is the most widely cultivated of these Annona species. Annona squamosa is semi-(or late) deciduous, and 3 to 8 metres (10 to 26 feet) tall, similar to soursop (Annona muricata). It is a native of tropical climate in the Americas, and Spanish traders aboard the Manila galleons docking in the Philippines brought it to Asia.

The atemoya or "pineapple sugar-apple", a hybrid between the sugar-apple and the cherimoya, is common in Taiwan, although it was first developed in the United States in 1908. The fruit is similar in sweetness to the sugar-apple; as its name suggests, it tastes like pineapple.
