The carrot (Daucus carota subsp. sativus) is a root vegetable, typically orange in color, though purple, black, red, white, and yellow cultivars exist, all of which are domesticated forms of the wild carrot, Daucus carota, native to Europe and Southwestern Asia. The plant probably originated in Persia and was originally cultivated for its leaves and seeds. The most commonly eaten part of the plant is the taproot, although the stems and leaves are also eaten. The domestic carrot has been selectively bred for its enlarged, more palatable, less woody-textured taproot. The carrot is a biennial plant in the umbellifer family, Apiaceae. At first, it grows a rosette of leaves while building up the enlarged taproot. Fast-growing cultivars mature within three months (90 days) of sowing the seed, while slower-maturing cultivars need a month longer (120 days). The roots contain high quantities of alpha- and beta-carotene, and are a good source of vitamin A, vitamin K, and vitamin B6. The United Nations Food and Agriculture Organization (FAO) reports that world production of carrots and turnips (these plants are combined by the FAO) for 2018 was 40 million tonnes, with 45% of the world total grown in China. Carrots are commonly consumed raw or cooked in various cuisines. Etymology The word is first recorded in English circa 1530 and was borrowed from the Middle French , itself from the Late Latin , from the ancient Greek ), originally from the Proto-Indo-European root ('horn'), due to its horn-like shape. In Old English, carrots (typically white at the time) were not clearly distinguished from parsnips: the two were collectively called or (from Proto-Indo-European 'edible root', cf. German or Russian ()). Various languages still use the same word for carrot as they do for root; e.g. the Dutch . History Both written history and molecular genetic studies indicate that the domestic carrot has a single origin in Central Asia. Its wild ancestors probably originated in Persia (regions of which are now Iran and Afghanistan), which remains the centre of diversity for the wild carrot Daucus carota. A naturally occurring subspecies of the wild carrot was presumably bred selectively over the centuries to reduce bitterness, increase sweetness and minimise the woody core; this process produced the familiar garden vegetable. When they were first cultivated, carrots were grown for their aromatic leaves and seeds rather than their roots. Carrot seeds have been found in Switzerland and Southern
