About
Psidium guajava, the common guava, yellow guava, lemon guava, or apple guava is an evergreen shrub or small tree native to South America. It is pollinated by insects. When cultivated, it is pollinated mainly by the common honey bee, Apis mellifera.
Where it grows
Guava is native to Peru. Some sources list it as also native to Mexico, Central America, the Caribbean, and the rest of South America.
Uses
Guava is an edible fruit, and can be eaten raw or cooked. The processing of the fruits yields by-products that can be fed to livestock. The leaves can also be used as fodder. It is also used by phasmid breeders to feed various stick insect species, including Extatosoma tiaratum and Eurycnema goliath, as well as various leaf insect species such as Pulchriphyllium giganteum, Pulchriphyllium bioculatum, and Phyllium monteithi.
