Apple Guava


Apple Guava

There are some 100 species of evergreen trees and shrubs in this genus, which has its origin in the Americas. The most widely cultivated species is P. guajava, the common guava. Other species with commercial importance include: P. guineense (Brazilian Guava), which has been crossed with P. guajava to produce smaller, hardier, more productive trees; P. littorale var. littorale (yellow strawberry guava), which bears relatively large, sweet, yellow fruits; and P. littorale var. longpipes (red strawberry guava), which has purple-red fruits, similar to strawberries in flavor. Guavas of various kinds have acid, aromatic fruits that are rich in vitamin C and in great demand in the tropics for making drinks and preserves. They are now naturalized in many parts of the tropics; though harvested for both culinary and medicinal purposes, the are a weed in some areas.

Evergreen shrub or small tree with peeling bark, 4-angled branchlets, and ovate to oblong-elliptic, prominently veined leaves, to 15cm (6in) long. White flowers, about 2.5cm (1in) across, with numerous stamens, appear in early summer, followed by rounded to pear-shaped, yellow fruits, to 10cm (4in) long, containing white or pink flesh and numerous seeds.
