Psidium guajava 學問

鑑別:
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.

一般資料:
Guavas are cultivated in many tropical and subtropical countries for their edible fruit. Mature trees are fairly cold-hardy and can survive as low as 5°C (41°F) 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.
