The plant is unique to tropical areas in that it blooms profusely after shading its leaves. This feature is common with temperate plants but less so with tropical plants, although fruiting can be seasonal.
The plant can be used to beautify open landscape or recreational gardens. Certain parts of the plant has been used for traditional medicine. Modern studies have shown that the plants contain secondary metabolites which can act as antimicrobial agents and other biological activity. For example a study by Bahoru et al, (2005)the plants contains secondary metabolites such as anthraquinones, flavonoids, flavan-3-ols, antioxidant and free radical scavenger.
