Yes, the cacao tree (Theobroma cacao) is an evergreen tree.
Cacao trees thrive in the humid, tropical rainforests and are known for continuously bearing leaves throughout the year. They are a vital part of the understory, growing beneath the forest canopy. This evergreen nature allows for a continuous production cycle, which is crucial for the sustained harvest of cocoa beans used in making chocolate and other cocoa products. Therefore, cacao retains its leaves year-round, classifying it as an evergreen.
