Strawberry Guava Plant is a large shrub or small tree that is native to South America and flourishes well in a warm climate. There are some good reasons to choose this plant over the common guava, including more attractive fruit and foliage, and a better tasting tropical fruit. Strawberry guava (Psidium littoralei) is also known as cattley guava, purple guava, or Chinese guava. Strawberry Guava Plant generally grows to heights between 6 and 14 feet (2-4.5 m.), although they can grow taller.
