Originally from southern Mexico (particularly Chiapas and Veracruz), Central American, and northern South America, the pawpaw is now cultivated in most tropical countries. In cultivation, it grows rapidly, fruiting within three years. It is, however, highly frost-sensitive, limiting its production to tropical climates.
Two kinds of pawpaw are commonly grown. One has sweet, red or orange flesh, and the other has yellow flesh; in Australia, these are called “red papaya” and “yellow pawpaw”, respectively. Either kind, picked green, is called a “green papaya”.
The pawpaw is a small, sparsely branched tree, usually with a single stem growing from 5 to 10 m tall, with spirally arranged leaves confined to the top of the trunk. The leaves are large, 50-70 cm in diameter, deeply palmately lobed, with seven lobes. Unusually for such large plants, the trees are dioecious. The flowers are sweet-scented, open at night and are moth-pollinated.
