The word broccoli comes from the Italian plural of broccolo, which means “the flowering crest of a cabbage”, and is the diminutive form of brocco, meaning “small nail” or “sprout”. Broccoli is often boiled or steamed but may be eaten .
Habitat: Broccoli is native to Mediterranean Region. It is a result of careful breeding of cultivated leafy cole crops in the northern Mediterranean starting in about the 6th century BC. Since the Roman Empire broccoli has been considered a uniquely valuable food among Italians. Broccoli was brought to England from Antwerp in the mid-18th century by Peter Scheemakers. Broccoli was first introduced to the United States by Italian immigrants, but did not become widely known there until the 1920s.
Broccoli is an herbaceous annual or biennial plant grown for its edible flower heads which are used as a vegetable. The broccoli plant has a thick green stalk, or stem, which gives rise to thick, leathery, oblong leaves which are gray-blue to green in color. The plant produces large branching green flower heads covered with numerous white or yellow flowers. Broccoli can be annual or biennial depending on the variety and can grow to 1 m (3.3 ft) in height. Broccoli may also be referred to as sprouting broccoli and likely originates from the Mediterranean although the exact location has not been determined……..CLICK & SEE THE PICTURES
Broccoli plants in a nursery:
There are three commonly grown types of broccoli. The most familiar is Calabrese broccoli, often referred to simply as “broccoli”, named after Calabria in Italy. It has large (10 to 20 cm) green heads and thick stalks. It is a cool season annual crop. Sprouting broccoli has a larger number of heads with many thin stalks. Purple cauliflower is a type of broccoli sold in southern Italy, Spain, and the United Kingdom. It has a head shaped like cauliflower, but consisting of tiny flower buds. It sometimes, but not always, has a purple cast to the tips of the flower buds.
Other cultivar groups of Brassica oleracea include cabbage (Capitata Group), cauliflower and Romanesco broccoli (Botrytis Group), kale and collard greens (Acephala Group), kohlrabi (Gongylodes Group), Brussels sprouts (Gemmifera Group), and kai-lan (Alboglabra Group). Rapini, sometimes called “broccoli raab” among other names, forms similar but smaller heads, and is actually a type of turnip (Brassica rapa). Broccolini or “Tenderstem broccoli” is a cross between broccoli and Chinese broccoli. Beneforté is a variety of broccoli containing 2-3 times more glucoraphanin that was produced by crossing broccoli with a wild Brassica variety, Brassica oleracea var villosa.
Succeeds in full sun in a well-drained fertile preferably alkaline soil. Tolerates a pH in the range 4.3 to 8.3. Prefers a heavy soil. Succeeds in any reasonable soil. Succeeds in maritime gardens. Some forms are very cold-hardy, tolerating temperatures down to about -17°c. Broccoli is closely related to the cauliflowers (C. oleracea botrytis) and is often grown for its edible young flowering stems which, by careful selection of varieties, can be available almost all year round from early summer right round to late spring. There are many named varieties and these can be classified into three main groups:- Calabrese, which matures in summer and autumn, is the least cold-hardy form. It produces green, or sometimes purple, flowering heads. Some forms will produce a number of side shoots once the main head has been harvested, though other forms seem unable to do this. Romanesco matures in late summer and the autumn. It has numerous yellowish-green conical groups of buds arranged in spirals. Given a little protection from the cold, it is possible to produce a crop throughout the winter. Unlike the other types of broccoli, romanesco seems unable to produce side shoots once the main head has been harvested. Sprouting broccoli is the most cold-hardy group. It does not form a central head like the other two groups but instead produces a mass of side shoots from early spring until early summer. The more you harvest these shoots, especially if you do so before the flowers open, then the more shoots the plant produces. A good companion for celery and other aromatic plants since these seem to reduce insect predations. Grows badly with potatoes, beet and onions. Grows well with potatoes, beet and onions according to another report.
Seed – sow sprouting broccoli in a seedbed outdoors in March to May. Plant out in June. Do not let the seedlings get overcrowded or they will soon become leggy and will not make such good plants. If your seedlings do get leggy, it is possible to plant them rather deeper into the soil – the buried stems will soon form roots and the plant will be better supported. Romanesco and calabrese are often sown in situ in the spring.
Edible Uses :
Edible Parts: Flowers; Leaves.
Young flowering stems and leaves – raw or cooked. The shoots of sprouting broccoli are harvested when about 10cm long, and before the flowers open, the shoots look somewhat like a small white or purple cauliflower and have a delicious flavour. They are considered to be a gourmet vegetable. When picking the stems, make sure that you leave behind a section of the stem with leaves on it, since the plants will often produce new side shoots from the leaf axils. Calabrese and Romanesco plants produce a central inflorescence rather like a small cauliflower, which are sometimes followed by a number of smaller flowering shoots. They usually come into bearing in the late summer or autumn and are very productive if they are regularly harvested. Sprouting broccoli plants come into production in late winter to early spring and can be very heavy bearing over a period of two months or more so long as all the flowering stems are harvested before coming into flower.
Broccoli is high in vitamin C and dietary fiber. It also contains multiple nutrients with potent anti-cancer properties, such as diindolylmethane (DIM) and small amounts of selenium. A single serving provides more than 30 mg of vitamin C and a half-cup provides 52 mg of vitamin C. DIM is a potent modulator of the innate immune response system with anti-viral, anti-bacterial and anti-cancer activity. Broccoli also contains the compound glucoraphanin, which can be processed into an anti-cancer compound sulforaphane, though the anti-cancer benefits of broccoli are greatly reduced if the vegetable is boiled. Broccoli is also an excellent source of indole-3-carbinol, a chemical which boosts DNA repair in cells and appears to block the growth of cancer cells.Sulforaphane, another compound in broccoli has been shown to stop over-rapid aging.
Boiling broccoli reduces the levels of suspected anti-carcinogenic compounds, such as sulforaphane, with losses of 20–30% after five minutes, 40–50% after ten minutes, and 77% after thirty minutes. However, other preparation methods such as steaming, microwaving, and stir frying had no significant effect on the compounds.
Broccoli has the highest levels of carotenoids in the brassica family. It is particularly rich in lutein and also provides a modest amount of beta-carotene
*Broccoli can provide us with some special cholesterol-lowering benefits if we cook it by steaming. The fiber-related components in broccoli do a better job of binding together with bile acids in our digestive tract when they’ve been steamed. When this binding process takes place, it’s easier for bile acids to be excreted, and the result is a lowering of your cholesterol levels.
*Raw broccoli still has cholesterol-lowering ability—just not as much.
*Broccoli has a strong, positive impact on our body’s detoxification system, and researchers have recently identified one of the key reasons for this detox benefit. Glucoraphanin, gluconasturtiian, and glucobrassicin are 3 glucosinolate phytonutrients found in a special combination in broccoli. This dynamic trio is able to support all steps in body’s detox process, including activation, neutralization, and elimination of unwanted contaminants. Isothiocyanates (ITCs) are the detox-regulating molecules made from broccoli’s glucosinolates, and they help control the detox process at a genetic level.
*Broccoli may help us solve our vitamin D deficiency epidemic. When large supplemental doses of vitamin D are needed to offset deficiency, ample supplies of vitamin K and vitamin A help keep our vitamin D metabolism in balance. Broccoli has an unusually strong combination of both vitamin A (in the form of beta-carotene) and vitamin K. For people faced with the need to rebuild vitamin D stores through vitamin D supplements, broccoli may be an ideal food to include in the diet.
*Broccoli is a particularly rich source of a flavonoid called kaempferol. Recent research has shown the ability of kaempferol to lessen the impact of allergy-related substances on our body. This kaempferol connection helps to explain the unique anti-inflammatory benefits of broccoli, and it should also open the door to future research on the benefits of broccoli for a hypoallergenic diet.
