The water apple is an evergreen tree with shiny leaves. The tree can shoot up rapidly to some 32 feet tall. Its trunk can grow to 15 feet (4.5 m.) around. Shoots grow in a bright burgundy color, maturing to pinkish beige. The showy flowers are bright and abundant. They grow in on the upper trunk of the tree and mature branches in clusters. Each blossom has a funnel-like base topped by green sepals, pinkish-purple or red-orange petals, and numerous stamens.
