Edible parts are the nuts, leaves, palm hearts, and fruits. The jelly-like immature endosperm is eaten or consumed as a drink. The hard seed is used as a substitute for ivory. It is used as buttons and in craft making. The leaves are used as a thatching material. Plants are grown from seeds but germination is slow and can take up to 12 months.

Cultivation details

Industrial Crop: Vegetable ivory  Management: Standard  Regional Crop

A plant from the warm tropics, though it can tolerate occasional short-lived temperatures down to around freezing[423 ]. Prefers a moist soil and a warm, sheltered position[314 ]. A slow-growing plant, it can take from 7 - 25 years from a young seedling before it starts to produce fruit[423 ]. The flowers are heavily scented[423 ]. A dioecious species, both male and female forms need to be grown if fruit and seed are required[768 ].

Carbon Farming

  • Industrial Crop: Vegetable ivory  Large hard seeds to substitute ivory.
  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
