The Annonaceae family is a large plant family with a great diversity of species in tropical regions.

The Annonaceae is a family of angiosperms mainly distributed in the tropics. Its members are mostly evergreen trees or shrubs, with a few being climbing in habit, and they grow mainly in the tropical and subtropical regions of Asia, Africa and the Americas. The sugar apple (Annona squamosa), also commonly known as custard apple, belongs to this family. With its rich variety of species and diverse uses, it holds an important place among tropical plants.

In terms of morphology, Annonaceae plants mostly have alternate, simple leaves with entire margins and no stipules. The flowers are usually bisexual, with generally six petals arranged in two whorls, and numerous stamens that are densely packed. The fruits are mainly aggregate fruits and berries, and many species have soft, sweet flesh when ripe.

The genus with the highest economic value in this family is Annona, whose fruits can be eaten directly and which has already been cultivated in some areas of South China. Besides fruit trees, the flowers of ylang-ylang (Cananga odorata) can be used to extract essential oil, which is an important raw material for the perfume industry; species such as the climbing ylang-ylang (Artabotrys) and the guafumu (Fissistigma) are of greater interest for garden ornamentation and folk uses.

In terms of habit, most Annonaceae plants prefer warm, humid climates and have weak cold tolerance, making them suitable for planting in areas with no frost or a very short frost period. Propagation is mainly by sowing, and saplings can also be raised by grafting and other methods. When cultivating them, it is best to choose a sunny site with good drainage and to manage wind protection and cold protection well, so that the plants will grow better.
