This fast growing tree has a small canopy, and can be intercropped with many tree species. It prefers alluvial soils and tolerates minimal flooding. Some seem adapted to deep and prolonged flooding. Macambo also does well in upland environments. The tree slowly increases in size as it ages, and can be very productive. It coppices fairly well, and can produce fruit at times when other fruits are scarce.
Aril eaten fresh or used to prepare juice or ice creams. Traditionally mixed with achiote (Bixa orellana L.) and sugar to make a sweet dessert. The seeds are consumed roasted, boiled, in pastry, and to prepare chocolate. The bad quality fruit are used to animal food.
