Casasia clusiifolia, also called the sevenyear apple, is a species of plant belonging to the family Rubiaceae. It is common in Florida.
Seven year apple is an evergreen shrub or small tree.
The plant is sometimes gathered from the wild for local use of its edible fruit and its wood.
Tolerates high levels of salt in the soil.
Plants can flower and fruit all year round, though most flowering occurs during the warm season.
A dioecious species, both male and female forms need to be grown if fruit and seed are required.
When fully ripe, the fruit is soft, wrinkled and prune-like with a black, jelly-like pulp that has a flavour somewhat like liquorice. The fruit is eaten by making a hole at one end and sucking the pulp out through it.
