Beta vulgaris (beet) is a species of flowering plant in the subfamily Betoideae of the family Amaranthaceae. It is a perennial plant usually growing up to 120 centimetres (4 ft) tall. Three subspecies are typically recognised. The wild ancestor of all the cultivated beets is the sea beet (Beta vulgaris subsp. maritima), with several modern cultivars all belonging to B. vulgaris subsp. vulgaris. Some of the most popular cultivar groups include: the sugar beet (used to produce table sugar), the root vegetable known as the beetroot or garden beet, the leaf vegetable known as chard or spinach beet or silverbeet, and mangelwurzel (a fodder crop).
