Annona reticulata is a small deciduous or semi-evergreen
Description
It is a small deciduous or semi-evergreen tree reaching 8 metres (26 ft) to 10 metres (33 ft) tall with an open, irregular crown.[8][9]
The slender leaves are hairless, straight and pointed at the apex (in some varieties wrinkled), 10 centimetres (3.9 in) to 20 centimetres (7.9 in) long and 2 centimetres (0.79 in) to 7 centimetres (2.8 in) wide.[8][9] The yellow-green flowers are generally in clusters of three or four 2 centimetres (0.79 in) to 3 centimetres (1.2 in) diameter, with three long outer petals and three very small inner ones.[8][9] Its pollen is shed as permanent tetrads.[10]
The fruits vary in shape, heart-shaped, spherical, oblong or irregular.[8][9] The size ranges from 7 centimetres (2.8 in) to 12 centimetres (4.7 in), depending on the cultivar. When ripe, the fruit is brown or yellowish, with red highlights and a varying degree of reticulation, depending again on the variety. The flesh varies from juicy and very aromatic to hard with a repulsive taste.[8][9] The flavor is sweet and pleasant, akin to the taste of 'traditional' custard.[9]
Distribution and habitat
Possibly a native of the Caribbean[11] and Central America,[2] Annona reticulata is now pantropical.[11] It grows from sea level to 1,500 metres (5,000 ft) altitude in areas of Central America that have alternating wet and dry seasons.[8][9] It is cultivated and naturalized in many tropical places including Southeast Asia, Taiwan, India, Pakistan, Australia, and Africa.[2][8][9][11][12] In India, the species has migrated from initial cultivation into the wild.[8]
Climate
Although the tree grows optimally in
Cultivation
Seeds can be propagated.[13][14] Other techniques for cultivation are grafting and budding.[13][14][8] The tree produces 45 kg of fruits per year. In Asia, the season lasts from July to September, and in the Caribbean, it runs from February to April.[14]
Uses
Food
Custard apple can be eaten raw, out of hand as a fresh fruit. It is not as popular as the
Propagation
A. reticulata may be grown in home gardens, even though it may not be as popular as the sugar apple (A. squamosa). It has value as rootstock for superior Annona species, such as the sugar apple, especially under humid conditions. It is also a genetic resource for hybridization.[8]
Other
The leaves and the branches can be used for tanning as they contain blue pigments. Wrappers, ornaments and hats can be made from the inner bark. The wood is soft and can be used to make utensiles,[13] even though, it is weak and of bad quality.[14]

Risk and impact
Annona reticulata is known to be an invasive plant.[8] A PIER risk assessment gave a score of 11 for the Annona reticulata. It negatively impacts the population cultivating the crop as all parts of the tree (except the fruit) are toxic, possibly causing problems for human health.[8]

Traditional medicine
Various traditional medicine uses have been reported over centuries for its dried fruits, bark, or leaves.[8][9]
