Species Card Details

Importance:

Marama bean is a drought-tolerant perennial legume of southern Africa which has incredible potential to be developed into an agricultural important crop plant. The seeds and tubers are edible, nutritious (high protein content) and a palatable food source that are collected and consumed locally. When cooked or roasted, the seeds develop a rich, nutty flavour reminiscent of coffee beans or roasted cashews. It can also be cooked with maize, ground into flour, or used to create a warm beverage. It is often used in the preparation of cosmetics
