Strawberry-guava

Psidium cattleyanum (World Plants: Psidium cattleianum), commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m (6 ft 7 in – 19 ft 8 in) tall) in the Myrtaceae (myrtle) family. The species is named in honour of English horticulturist William Cattley. The red-fruited variety, P. cattleyanum var. cattleyanum, is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. The yellow-fruited variety, P. cattleyanum var. littorale is variously known as yellow cattley guava, yellow strawberry guava, yellow cherry guava, lemon guava and in Hawaii as waiawī.

It is an invasive plant in many areas and is considered the most invasive species in Hawaii, although it has some economic uses, including its edible fruit.
