Is a genus of about 100 species of tropical shrubs and small trees in the myrtle family Myrtaceae, native to Mexico, the Caribbean, Central America and northern South America. In Hindi they are they are typical Myrtoideae, with tough dark leaves that are opposite, simple, elliptic to ovate and 5-15 cm long. The flowers are white, with five petals and numerous stamens. The fruit are juicy. The guava makes an ideal houseplant as long as it remains moist. Spray the foilage to keep it healthy and pinch new growth to keep the plant bushy.In several tropical regions, including Hawai»i, some species (namely Cattley Guava, P. littorale) have become invasive weed shrubs. On the other hand, several species have become very rare and at least one (Jamaican Guava, P. dumetorum), is already extinct.Guavas are cultivated in many tropical and subtropical countries for their edible fruit. Several species are grown commercially; apple Guava (P. guajava) and its cultivars are those most commonly traded internationally.Mature trees of most species are fairly cold-hardy and can survive as low as 5°C for short periods of time, but younger plants will not survive. They are known to survive in Northern Pakistan where they can get down to 5°C or lower during the night. Guavas are also of interest to home growers in temperate areas, being one of the very few Tropical Fruits that can be grown to fruiting size in pots indoors.
