Броколите са растение от семейство зелеви, чиято цветна глава се използва като зеленчук. Думата броколи произлиза от италиански (broccolo) и означава в множествено число "цъфтящи върхове на зелето". Броколите обикновено се варят във вода или на пара, но могат да се консумират сурови и стават популярни като суров зеленчук сервиран в ордьоври. Броколите се класифицират в групата на сорт Италика от вида Brassica oleracea. Броколите имат големи цветни глави, обикновено зелени на цвят, подредени като разклонени клони върху дебело стъбло, годно за консумация. Цветните глави са заобиколени от листа. Броколите приличат най-много на карфиол, но са различна група от същия вид. Те произхождат от култивирани зелеви листни култури в северното Средиземноморие около 6-ти век пр.н.е. От времето на Римската империя, броколите се смятат за уникално ценна храна сред италианците. Те са пренесени в Англия от Антверпен в средата на 18-ти век от Peter Scheemakers.В Съединените щати за пръв път са внесени от италиански имигранти, но не стават широко известни до 1920 г.

'''Broccoli''' is a plant in the [[Brassicaceae|cabbage family]], whose large flower head is used as a vegetable. The word broccoli, from the Italian plural of ''{{lang|it|[[wikt:broccolo#Italian|broccolo]]}}'', refers to "the flowering top of a cabbage".<ref>{{cite dictionary|title=broccoli|encyclopedia=Merriam-Webster's Collegiate Dictionary|edition=11th|page=156|isbn=978-0-87779-809-5|url=http://www.merriam-webster.com/dictionary/broccoli|accessdate=24 August 2009}}</ref> Broccoli is usually boiled or steamed, but may be eaten raw and has become popular as a raw vegetable in [[hors d'œuvre]] trays.
Broccoli is classified in the Italica [[cultivar group]] of the species ''[[Brassica oleracea]]''. Broccoli has large [[flower head]]s, usually green in color, arranged in a tree-like fashion on [[branches]] [[sprouting]] from a thick, edible [[plant stem|stalk]]. The mass of flower heads is surrounded by leaves. Broccoli most closely resembles [[cauliflower]], which is a different cultivar group of the same species.
Broccoli was derived from cultivated leafy cole crops in the Northern Mediterranean in about the 6th century BCE <ref name="VB">{{cite journal|last = Maggioni|first = Lorenzo|coauthors = von Bothmer., R., Poulesen, G., Branca, F.|title = Origin and Domestication of Cole Crops (''Brassica oleracea'' L.): Linguistic and Literary Considerations|journal = Economic Botany|volume = 64|issue = 2|pages = 109-123|year = 2010}}</ref>.

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&nbsp;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), and [[Brussels sprout]]s (Gemmifera Group). [[Chinese broccoli]] (Alboglabra Group) is also a cultivar group of ''Brassica oleracea''.<ref name=Dixon2007>{{cite book|last1 = Dixon|first1 = G.R.|year = 2007|title = Vegetable brassicas and related crucifers|isbn = 978-0-85199-395-9|publisher = CABI|location = Wallingford}}</ref> [[Rapini]], sometimes called "broccoli rabe" among other names, forms similar but smaller heads, and is actually a type of turnip (''[[Brassica rapa]]''). [[Broccolini]] or "Tender Stem Broccoli" is a cross between broccoli and [[kai-lan |Chinese broccoli]].

In North America, production is primarily in [[California]]. The seasonal average [[Free On Board|f.o.b.]] shipping-point price for cauliflower in 2004 was $33.00 per 100&nbsp;pounds ($0.73/kg) according to the National Agricultural Statistics Service, USDA.{{Citation needed|date=April 2010}}<!--as fresh produce prices are notorious for their volatility, a 6-year-old price has little relevance-->

Broccoli is a cool-weather crop that does poorly in hot summer weather. Broccoli grows best when exposed to an average daily temperature between {{convert|18|and|23|°C|°F}}.<ref>{{cite web|title = HGIC 1301 Broccoli|last = Smith|first = Powell|date = June 1999|publisher = [[Clemson University]]|url = http://www.clemson.edu/extension/hgic/plants/vegetables/crops/hgic1301.html|accessdate = 25 August 2009}}</ref>
When the cluster of flowers, also referred to as a "head" of broccoli, appear in the center of the plant, the cluster is green. Garden pruners or shears are used to cut the head about an inch from the tip. Broccoli should be harvested before the flowers on the head bloom bright yellow.<ref>{{cite encyclopedia|title = Broccoli|last = Liptay|first = Albert|year = 1988|publisher = [[World Book Encyclopedia|World Book, Inc.]]}}</ref>
