Buckwheat (Fagopyrum esculentum) is a plant cultivated for its grain-like seeds and as a cover crop. Despite the name, Buckwheat is not related to wheat, nor is it a grass. It is actually related to Sorrel, Knotweed and Rhubarb. It has large triangular, hard brown seeds, similar to that of a Beech nut. It is a short season crop which does well on low fertility, acidic soils – but it must be well drained. Too much fertiliser, especially Nitrogen, can reduce yields. Blooms are a pinky/white. The presence of pollinators greatly increases the yield.
