The carrot is a root vegetable, typically orange or white in colour with a woody texture. The edible part of a carrot is a taproot. It is a biennial plant which grows a rosette of leaves in the spring and summer while building up the stout taproot, which stores large amounts of sugars for the plant to flower in the second year. The flowering stem grows to about 1 m tall, with umbels of white flowers.

Carrots can be eaten raw, whole, chopped or shaved into salads for colour, and are also often chopped and cooked in soups and stews. A well known dish is Carrots Julienne. One can also make carrot cake and carrot pudding. The greens are edible as a leaf vegetable, but are rarely eaten. Together with onion and celery, carrots are one of the primary vegetables used in a mirepoix to make various broths.

Since the late 1980s, baby carrots or mini carrots, carrots that have been peeled and cut into uniform cylinders, have been a popular ready-to-eat snack food in many supermarkets.

Beta carotene, a dimer of Vitamin A, is abundant in the carrot and gives this vegetable its characteristic orange colour. Furthermore, carrots are rich in dietary fiber, antioxidants, and minerals.

Carrot juice is also widely marketed.

History

The wild ancestors of the carrot are likely to have come from Afghanistan which remains the centre of diversity of D. carota. The familiar wild plant wild carrot, sometimes called "Queen Anne's lace", is a relative of the garden carrot; garden carrots that run to seed soon revert to their wild prototype, with a forking carroty-smelling, edible root that quickly becomes too woody and bitter to eat. The Parsnip is a close relative of the carrot.

Cultivars

Carrot cultivars can be grouped into two broad classes, eastern carrots and western carrots. More recently, a number of novelty cultivars have been bred for particular characteristics.

Eastern carrots

Eastern carrots were domesticated in Central Asia, probably in modern-day Afghanistan in the 10th century or possibly earlier. Those of the eastern carrot that survive to the present day are commonly purple or yellow in colour, and often have branched roots. The purple colour common in these carrots comes from anthocyanin pigments.

Western carrots

The Western carrot emerged in the Netherlands in the 15th or 16th century, its orange colour making it popular in those countries as an emblem of the House of Orange and the struggle for Dutch independence. The orange colour results from abundant carotenes in these cultivars. While orange carrots are nearly ubiquitous in the West, other colours do exist, including white, yellow, red, and purple. These other colours of carrot are raised primarily as novelty crops.

The Vegetable Improvement Center at Texas A&M University has developed a purple-skinned, orange-fleshed carrot, the BetaSweet, with substances to prevent cancer, which has recently entered commercial distribution.

Western carrot cultivars are commonly classified by their root shape:

  • 'Imperator' carrots are the carrots most commonly sold whole in U.S. supermarkets; their roots are longer than other cultivars of carrot, and taper to a point at the tip.
  • 'Nantes' carrots are nearly cylindrical in shape, and are blunt and rounded at both the top and tip. Nantes cultivars are often sweeter than other carrots.
  • 'Danvers' carrots have a conical shape, having well-defined shoulders and tapering to a point at the tip. They are somewhat shorter than Imperator cultivars, but more tolerant of heavy soil. Danvers cultivars are often pureed as baby food.
  • 'Chantenay' carrots are shorter than other cultivars, but have greater girth, sometimes growing up to 8 cm (3 inches) in diameter. Shapewise, they have broad shoulders and taper towards a blunt, rounded tip. They are most commonly diced for use in canned or prepared foods.

While any carrot can be harvested before reaching its full size as a more tender "baby" carrot, some fast-maturing cultivars have been bred to produce smaller roots. The most extreme examples produce round roots about 2.5 cm (1 inch) in diameter. These small cultivars are also more tolerant of heavy or stony soil than long-rooted cultivars such as 'Nantes' or 'Imperator'. The "baby carrots" sold ready-to-eat in supermarkets, are however often not from a smaller cultivar of carrot, but are simply full-sized carrots that have been sliced and peeled to make carrot sticks of a uniform shape and size.

Carrot flowers are pollinated primarily by bees. Seed growers use honeybees or mason bees for their pollination needs.

Carrots are used as food plants by the larvae of some Lepidoptera species including Common Swift, Garden Dart, Ghost Moth, Large Yellow Underwing and Setaceous Hebrew Character.

Novelty carrots

Food enthusiasts and researchers have obtained other varieties of carrots through traditional breeding methods. One particular species lacks the usual orange pigment from carotenes, owing its white colour to a recessive gene for tocopherol (Vitamin E). Derived from Daucus carota L. and patented (US patent #6,437,222) at the University of Wisconsin-Madison, the variety is intended to supplement dietary intake of Vitamin E.

Trivia

In 2005, a poll of 2,000 people revealed that the carrot was Britain's 3rd favourite culinary vegetable.

For the purposes of the European Union's "Council Directive 2001/113/EC of 20 December 2001 relating to fruit jams, jellies and marmalades and sweetened chestnut purée intended for human consumption" carrots can be defined as a fruit as well as a vegetable. This is because carrot jam is a Portuguese delicacy.

A common urban legend is that carrots help with a persons night vision. It is believed that it was disinformation introduced in 1940 by John "Cat's Eyes" Cunningham during the Battle of Britain as an attempt to cover up the discovery and use of radar technologies (see Snopes investigation in the external links). It reinforced existing German folklore and helped to encourage children to eat the vegetable. Lack of Vitamin A can, however, cause poor vision and can be restored by adding Vitamin A back into the diet.

The world's largest carrot was grown in Palmer, Alaska by John Evans in 1998, weighing 8.614 kg (18.99 pounds).

Carrots are also traditionally used as noses when building snowmen.
