Lemon (citrus limon)
It"s now grown in warm countries throughout the world. It is generally considered that the Mediterranean regions provide the best growing conditions.
It"s a strange fact that most Florida orange trees have lemon-tree roots; while all Californian lemon trees have orange-tree roots. One citrus tree can, in fact, with the botanist"s help have lemons, limes, oranges, tangerines, kumquats and grapefruit growing on its branches at the same time.
Lemons are rich in vitamin C, as well as mineral salts; and 28g/1 fl oz of juice contains approximately 40 grains of citric acid. It"s this acid that acts on other fruit - like bananas and avocados (and some vegetables) - to help them keep their colour. A slice of lemon r a little juice should be used when boiling sweet potatoes, Jerusalem artichokes, stems of Swiss chard, seakale, or any other vegetable that tends to become discoloured.
