|The beetroot is the taproot portion of the beet plant, usually known in North America as the beet, also table beet, garden beet, or red or golden beet. It is several of the cultivated varieties of Beta vulgaris grown for their edible taproots and their leaves (called beet greens). These varieties have been classified as B. vulgaris subsp. vulgaris Conditiva Group.
Generally, 55 to 65 days are needed from germination to harvest of the root. All cultivars can be harvested earlier for use as greens. (Source: Wikipedia)
