				Strawberry Guava - Psidium cattleianum Family: Myrtaceae THIS PAGE IS UNDER CONSTRUCTION. Status: Invasive Location info: Strawberry guava (Psidium cattleianum) is a small tree (2-6 m tall), bearing small red or yellow fruit, which are somewhat sour but sometimes eaten or made into jam. Yellow-fruited varieties are known in Hawai?i as waiaw?. It is closely related to common guava, and like that species is a widespread, highly invasive species in tropical areas, especially Hawai?i. It tends to form dense, monotypic stands which prevent regrowth of native species, and is very difficult to eradicate. Info: Strawberry guava is a very serious, habitat-altering pest in many parks and preserves in Hawaii where it poses a major threat to Hawaii's rare endemic flora and fauna. It forms shade-casting thickets with dense mats of surface feeder roots that make it difficult for other species to coexist. Characteristics that promote strawberry guava's success as an invader include its prolific fruiting and aggressive vegetative growth, its tolerance of shade and heavy leaf litter, and possibly through production of toxic chemicals in its leaves that prevent the growth of other plant species.
