Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Summary

Tylosema esculentum, commonly known as Marama Bean or Gemsbok Bean is a perennial legume native to Southern Africa. It is long-lived and grows at least 3 m. The tuber can grow at least 10 kg, which makes the plant capable of growing under harsh environmental conditions.The seeds develop in legume pods. Marama bean has no medicinal uses but is an important food crop. The seeds are cooked by roasting or boiling. Immature seeds and stems are also cooked. The seeds yield edible oil with taste and consistency comparable to that of almond oil. The tuber is baked, boiled, or roasted.

Edible Uses

Edible Parts: Oil  Root  Seed
Edible Uses: Oil

Seed - cooked. After roasting, the seeds have a delicious, nutty flavour similar to coffee beans or roasted cashews[301 ]. They may be boiled with maize meal or ground into flour to prepare a porridge or a coffee- or cocoa-like drink[299 ]. The roasted seeds have sometimes been used as a culinary substitute for almonds[299 ]. The seeds have a protein content around 30% (approaching that of the soya bean) and an oil content around 40% (approaching that of the peanut)[301 ]. The immature seeds and stems may be eaten cooked as a vegetable or in soups[299 ]. A coffee-like beverage can be made from the seeds[317 ]. An edible oil is obtained from the seed[301 ]. Similar to almond oil in consistency and taste[299 , 301 ]. Golden-yellow, with a nutty odour and a pleasant, although slightly bitter flavour[299 ] Tuber - cooked. The sweet-tasting tuber can be baked, boiled or roasted[301 , 317 ]. Young tubers have a sweet and pleasant taste and the texture has been described as similar to that of artichoke[299 ]. Tubers older than 2 years become fibrous and bitter and are usually not eaten, but they are an important emergency source of water for humans and animals[299 ].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

Management: Standard  New Crop  Staple Crop: Protein  Wild Staple Crop

A plant of the drier tropics, marama bean occurs naturally in an extreme environment with high temperatures and very low rainfall[299 ]. It can be found at elevations up to 1,500 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 30°c, but can tolerate 16 - 50°c[418 ]. It prefers a mean annual rainfall in the range 300 - 600mm, but tolerates 150 - 1,600mm[398 , 418 ]. The plant probably survives droughts by drawing on water stored in the tuber, which shrinks greatly in dry years[418 ]. Requires a sunny position. Grows best in a deep, loose, sandy soil[418 ]. Prefers a pH in the range 5.5 - 7, tolerating 5 - 7.5[418 ]. An extremely drought-tolerant plant, it can grow in areas where rainfall is so slight and erratic that in some years almost no rain falls at all[418 ]. In its native habitat surface water is usually available only for 8 weeks a year, though in the fine-grained sandy soils water may remain in the root zone for as long as 2 months after a rainfall[418 ]. Unlike most members of this plant family, this species does not form nitrogen nodules on the roots[299 ].

Carbon Farming

  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • New Crop  Most new crops were important wild plants until recently, although some are the result of hybridization. They have been developed in the last few, decades. What they have in common is that they are currently cultivated by farmers. Examples include baobab, argan, and buffalo gourd.
  • Staple Crop: Protein  (16+ percent protein, 0-15 percent oil). Annuals include beans, chickpeas, lentils, cowpeas, and pigeon peas. Perennials include perennial beans, nuts, leaf protein concentrates, and edible milks.
  • Wild Staple Crop  Some wild plants have strong historical or contemporary use. Although they are not cultivated crops, they may be wild-managed.

Propagation

Seed it should not be pre-soaked, though germination might be improved by scarification[299 ]. Germination starts to take place after about 9 days[299 ].
