Guava is a tropical round to pear-shaped fruit produced by the guava tree (Psidium guajava), of the family Myrtaceae. The tree is actually a small, white-flowered, oblong-leaved, glabrous shrub that originated in the warm regions of the Americas.
Guava is cultivated in many tropical countries because of its edible fruits, which are excellent for eating fresh or for making candies, preserves, jellies, jams, marmalades (goiabada), and juices. The fresh fruit is rich in vitamins A, B, and C and can be eaten raw or sliced and served with sugar and cream as a dessert.
The ripe fruit has a strong aroma which people either love or hate.
The plant is frost-sensitive. In several tropical regions it has become a pest.
