Carrot

Carrot, common name for some members of the Umbelliferae, a family (also called the parsley family) of chiefly biennial or perennial herbs of north temperate regions. Most are characterized by aromatic foliage, a dry fruit that splits when mature, and an umbellate inflorescence (a type of flattened flower cluster in which the stems of the small florets arise from the same point, like an umbrella). The seeds or leaves of many of these herbs have been used for centuries for seasoning or as greens (e.g., angelica, anise, caraway, chervil, coriander, cumin, dill, fennel, lovage, and parsley). The carrot, celery, and parsnip are vegetables of commercial importance. The common garden carrot (Daucus carota sativa) is a root crop, probably derived from some variety of the wild carrot (or Queen Anne's lace). In antiquity several types of carrot were grown as medicinals, and in Europe carrots have long been grown for use in soups and stews. The custom of eating carrots raw as a salad has become widespread in the 20th cent. Carrots are a rich source of carotene (vitamin A), especially when they are cooked. Several types of carrot have also been cultivated since ancient times as aromatic plants. Some are still planted as fragrant garden ornamentals, such as the button snakeroot and sweet cicely. A few members of the Umbelliferae produce lethal poison; it was one of these, the poison hemlock, that Socrates was compelled to take. The water hemlock is also poisonous. Carrots are classified in the division Magnoliophyta, class Magnoliopsida, order Umbellales, family Umbelliferae.

Watercress

Watercress, hardy perennial European herb (Nasturtium officinale) of the family Cruciferae (mustard family), widely naturalized in North America, found in or around water. Often cultivated commercially for the small, pungent leaflets, it is used as a peppery salad green or garnish. Other plants of the genus are sometimes called watercress and are used similarly. Watercress was formerly used as a domestic remedy and against scurvy. The ornamental plant whose common name is nasturtium is unrelated. Watercress is classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.

Radish

Radish, herbaceous plant (Raphanus sativus) belonging to the family Cruciferae (mustard family), with an edible, pungent root sliced in salads or used as a relish. It is thought to be native to China; it spread to the Mediterranean area before Greek times and to the New World in the early 16th cent. There are many varieties, with white, red, or black roots of different shapes and sizes, some quite large. Radishes grow easily and quickly throughout temperate regions; they are a staple food in Japan and China, where they are generally pickled in brine. Radishes are classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.

Turnip

Turnip, garden vegetable of the same genus of the family Cruciferae (mustard family) as the cabbage; native to Europe, where it has been long cultivated. The two principal kinds are the white (Brassica rapa) and the yellow (B. napobrassica), which is known as the rutabaga, the Swedish turnip, or the swede. The rutabaga is grown extensively only in Europe, where it is believed to have originated during the Middle Ages as a cross between the white turnip and the cabbage. The turnip is one of the root crops used as a stock feed as well as for human food. The green leaves (greens) are often cooked like spinach. The turnip is a biennial cool-weather crop, grown mostly in cool climates. The worst turnip pests are the root maggot and the flea beetle; it is also attacked by clubroot fungus. Turnips are classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.

Cabbage

Cabbage, leafy garden vegetable of many widely dissimilar varieties, all probably descended from the wild, or sea, cabbage (Brassica oleracea) of the family Cruciferae (mustard family), found on the coasts of Europe. It is used for food for man and stock, mostly in Europe and North America. Well-known varieties of the species include the cabbages, broccoli, Brussels sprouts, cauliflower, collards, kale, and kohlrabi. All grow best in cool, moist climates. They are attacked mostly by insect pests. The true cabbages (var. capitata) include the white and red types and the Savoy type (grown mostly in Europe), with curly, loose leaves. Inexpensive and easily stored, cabbage is important in the diet of many poorer peoples. Popular cabbage dishes include sauerkraut and slaw (raw cabbage). Chinese cabbage, or petsai, chiefly a salad plant, is a separate species (B. pekinensis) grown in many varieties, especially in East Asia. Cabbages with multicolored leaves are becoming popular as ornamental border plants for flower gardens. Cabbages are classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.

Cauliflower (kô`lĭflou'ər, käl`ĭ–), variety of cabbage, with an edible head of condensed flowers and flower stems. Broccoli is the horticultural variety (botrytis); both were cultivated in Roman times. Cauliflower is classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae

Brussels sprouts, variety (gemmifera) of cabbage producing small edible heads (sprouts) along the stem. It is cultivated like cabbage and was first developed in Belgium and France in the 18th cent. Brussels sprouts are classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.

Broccoli (brŏk`əlē) [Ital.,=sprouts], variety of cabbage grown for the edible immature flower panicles. It is the same variety (Brassica oleracea botrytis) as the cauliflower and is similarly cultivated. Although known to the Romans, it became generally popular in the United States only in the 20th cent. Broccoli is classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.




Kohlrabi (kōl`rä`bē) [Ger. partly from Ital.,=turnip cabbage], plant (Brassica caulorapa, sometimes classified as var. caulorapa of the cabbage species) of the family Cruciferae (mustard family), with an edible, turniplike, swollen stem. It is a cool-weather plant grown more in Europe, where some varieties are used for fodder, than in America. The flavor is more delicate than that of some of the other cabbage plants. Kohlrabi is classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.

Lavender

Lavender, common name for any plant of the genus Lavandula, herbs or shrubby plants of the family Labiatae (mint family), most of which are native to the Mediterranean region but naturalized elsewhere. The true lavender (L. officinalis) has grayish foliage and small blue or pale purplish flowers (white in one variety). It is popular for herb gardens and is cultivated commercially or, more commonly, gathered wild for the fragrant flowers, valued for scenting linens and clothes and as the source of oil of lavender. The oil is distilled for use in perfumery, in toilet preparations (e.g., lavender water). Lavender is sometimes used as a flavoring. Spike lavender (L. latifolia), a broader-leaved, less fragrant species, yields spike-lavender oil, which is also used in perfumery and in varnishes and porcelain painting. Lavender is classified in the division Magnoliophyta, class Magnoliopsida, order Lamiales, family Labiatae.

Thyme

Thyme (tīm), any species of the genus Thymus, aromatic herbs or shrubby plants of the family Labiatae (mint family). The common thyme, which is used as a seasoning herb and yields a medicinal essential oil containing thymol, is the Old World T. vulgaris, an erect plant with grayish branches. It is cultivated mainly in Spain and in France. A compound derived from T. vulgaris, thymine, is used as a topical antifungal. The wild or creeping thyme, or mother-of-thyme (T. serpyllum), also used medicinally, is an Old World evergreen naturalized in North America and popular as a ground cover, edging, and rock plant. This was the wild thyme mentioned in Shakespeare's Midsummer Night's Dream. The Greeks used thyme as a temple incense, and it has been prized since ancient times as a honey plant. Thyme is classified in the division Magnoliophyta, class Magnoliopsida, order Lamiales, family Labiatae.
