Nearly 5,000 years ago, humans cultivated the guava fruit. It was called the Psidium dumetorum and is a part of the Myrtaceae family, endemic to Jamaica. Researchers recorded the last plant in 1976 in a streamside thicket in Clarendon, Jamaica. Researchers consider it extinct. The original guava plant was a pest that dominated all the other plants. It was called the strawberry guava, and it “grew across hundreds of thousands of acres of native forest, clearing out practically every other plant in its path” (Daily). Guava plants today aren’t so invasive, and the strawberry-pear hybrid is sweet and pleasant to eat.
