Daucus carota subsp. sativus produces thick, sweet, orange roots, commonly known as Carrots. It is from this plant that most domestic carrots are cultivated from. Carrots prefer growing in sunny locations with free draining, deep soil that encourages long straight roots. Raised beds or containers lifting the crown of the plant above 60cm (2') will also help to deter carrot fly, a low flying common pest which lays its eggs near the developing root. The subspecies Daucus carota subsp. sativus has evolved from the Wild Carrot species, Daucus carota, along with other subspecies that adapted to different climates in different regions of the world. Carrots can range in colour from white to yellow, red and purple depending on the variety, but all have large long tap roots. An example is Daucus carota subsp. carota that produces thin, bitter-tasting, white, but inedible roots.
