The cultivation of Guandu goes back at least 3000 years. The centre of origin is most likely India, from where it travelled to East Africa and by means of the slave trade to America. They found Guandu grains in the tombs of the Pyramid workers. It is a very sturdy bush that grows from seeds in poor soil, which will be improved in two ways, first by nitrogen that the plant takes from the air and fixes in the soil thereby fertilizing it; second its deep penetrating root system breaks hard soil thereby facilitating water penetration and aeration. These features of Guandu bushes make them good companions to other plants or trees that need lots of nitrogen in the soil. Guandu bushes need very little water so they grow well in dry climates, they like direct sun light. Guandu come in three main colors, green, beige and black, they are sold fresh, dried or canned. They cook quickly (30 minutes) and have a nutty taste. It is possible to germinate the grains for eating raw in salads or make them more digestible after cooking, germinated Guandu have a somewhat blander taste but vegetarians really like them.

STORING: Dried Guandu will keep forever in a cool dry place if you fend off the bugs, and you can do this by placing some hot chilies in the grain, in India they would place leaves and branches from the Neem tree, which is sometimes found in Latin America. Guandu grains are available all year round, but towards the end of the year demands increases and so does the price, but you can buy them fresh before November and freeze them, they will keep well.
