National colours of the United Kingdom National colours of the United Kingdom The national colours of the United Kingdom are usually identified as the combination of red, white and blue in that order. These colours are the same as in the flag of the United Kingdom. The colours of the flag are in turn taken from the flags of England (white and red) and of Scotland (blue and white), which have been combined to form the union flag; to this was later added a red saltire for Ireland. In maps of the 19th and 20th centuries, the territories of the British Empire were usually coloured red
Flax contains small amounts of cyanogenic glycoside; these are nontoxic when consumed in typical amounts, but may be toxic when consumed in large quantities of such staple foods such as cassava. Typical concentrations (for example, 0.48% in a sample of defatted dehusked flaxseed meal) can be removed by special processing. The soils most suitable for flax, besides the alluvial kind, are deep loams containing a large proportion of organic matter. Flax is often found growing just above the waterline in cranberry bogs. Heavy clays are unsuitable, as are soils of a gravelly or dry sandy nature. Farming flax requires few fertilizers
