Guava (from Spanish Guayaba; Goiaba in Portuguese) is a genus of about 100 species of tropical shrubs and small trees in the myrtle family Myrtaceae, native to the Caribbean, Central America and northern South America. The leaves are opposite, simple, elliptic to ovate, 5-15 cm long. The flowers are white, with five petals and numerous stamens. Psidium species are used as food plants by the larvae of some Lepidoptera species including Eupseudosoma aberrans, Snowy Eupseudosoma and Hypercompe icasia.
The fruit is edible, round to pear-shaped, from 3-10 cm in diameter (to 12 cm in some selected cultivars). It has a thin delicate rind, pale green to yellow at maturity in some species, pink to red in others, a creamy white or orange-salmon flesh with many small hard seeds, and a strong, characteristic aroma. It is rich in vitamins A, B, and C.
Guavas are cultivated in many tropical countries for their edible fruits. Several species are grown commercially; those listed right are the most important. The fruit is commonly eaten whole, but is often prepared in a variety of ways as a dessert. In Asia, raw guava is often dipped in salt or prune powder. Boiled guava is also extensively used to make candies, preserves, jellies, jams, marmalades (goiabada), and juices.
The plants are frost-sensitive. In several tropical regions, including Hawaii, some species have become invasive weed shrubs. It is also of interest for home growers in temperate areas, as one of the very few tropical fruit that can be grown to fruiting size in pots indoors.
