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 >>>

Edible Uses

Leaves - raw or cooked[183, 272]. Acceptable raw when added in small quantities to mixed chopped salads, otherwise the leaves are much better cooked[K]. They are rich in rutin. Seed - cooked as a cereal[2, 46, 100, 105, 272].The seed can also be sprouted and used in salads, or ground into a powder and used as a cereal[183]. An edible oil is obtained from the seed[177, 183].

Cultivation details

A very easily grown plant, it prefers dry sandy soils but succeeds in most conditions including poor, heavy or acid soils[160] and even sub-soils. Prefers a cool moist climate, also succeeds in dry and arid regions. Tartarian buckwheat is hardier and more resistant to cold than the more commonly grown buckwheat, F. esculentum, though it does not yield so highly[132]. Occasionally cultivated for its edible seed in Europe and the Himalayas[50, 51], there is at least one named variety[183]. 'Madawaska' is more cold hardy and drought tolerant than the type[183].
