Broccoli (Brassica oleracea var. italica) is an edible green plant in the cabbage family (family Brassicaceae, genus Brassica) whose large flowering head, stalk and small associated leaves are eaten as a vegetable. Broccoli is classified in the Italica cultivar group of the species Brassica oleracea. Broccoli has large flower heads, or florets, usually dark green, arranged in a tree-like structure branching out from a thick stalk, which is usually light green. Leaves surround the mass of flower heads. Broccoli resembles cauliflower, a different but closely related cultivar group of the same Brassica species.
It can be eaten either raw or cooked. Broccoli is a particularly rich source of vitamin C and vitamin K. Contents of its characteristic sulfur-containing glucosinolate compounds, isothiocyanates and sulforaphane, are diminished by boiling but are better preserved by steaming, microwaving or stir-frying.{{cite journal|last1=Nugrahedi|first1=Probo Y.|last2=Verkerk|first2=Ruud|last3=Widianarko|first3=Budi|last4=Dekker|first4=Matthijs|title=A Mechanistic Perspective on Process-Induced Changes in Glucosinolate Content in Brassica Vegetables: A Review|journal=Critical Reviews in Food Science and Nutrition|volume=55|issue=6|date=2015|issn=1040-8398|pmid=24915330|doi=10.1080/10408398.2012.688076|pages=823–838|s2cid=25728864|url=https://www.researchgate.net/publication/262977227}}
Rapini, sometimes called "broccoli rabe", is a distinct species from broccoli, forming similar but smaller heads, and is actually a type of turnip (Brassica rapa).{{Cite web|last=Main|first=Sandy|title=Rapini/Broccoli Raab|url=https://ucanr.edu/sites/scmg/The_Kitchen_Garden/Feature_Vegetables/Rapini_Broccoli_Raab/|url-status=live|access-date=13 September 2021|website=sonomamg.ucanr.edu|language=en-US|archive-url=https://web.archive.org/web/20150530100002/http://ucanr.edu/sites/scmg/The_Kitchen_Garden/Feature_Vegetables/Rapini_Broccoli_Raab/ |archive-date=30 May 2015 }}
Taxonomy
Brassica oleracea var. italica was described in 1794 by Joseph Jakob von Plenck in Icones Plantarum Medicinalium 6:29, t. 534.{{cite web |last1=Missouri Botanical Garden |title=Brassica oleracea var. italica |url=http://legacy.tropicos.org/Name/4102963 |website=tropicos.org |publisher=Missouri Botanical Garden |access-date=18 October 2023}} Like all the other brassicas, broccoli was developed from the wild cabbage (Brassica oleracea var. oleracea), also called colewort or field cabbage.
Etymology
The word broccoli, first used in the 17th century, comes from the Italian plural of {{lang|it|broccolo}}, which means "the flowering crest of a cabbage", and is the diminutive form of brocco, meaning "small nail" or "sprout".{{cite dictionary|title=Broccoli|encyclopedia=Online Etymology Dictionary|date=2022|accessdate=18 January 2023|url=https://www.etymonline.com/search?q=broccoli|archive-date=19 January 2023|archive-url=https://web.archive.org/web/20230119002022/https://www.etymonline.com/search?q=broccoli|url-status=live}}
History
Broccoli resulted from the breeding of landrace Brassica crops in the northern Mediterranean starting in about the sixth century BCE.{{cite journal|last1=Maggioni|first1=Lorenzo|title=Origin and Domestication of Cole Crops (Brassica oleracea L.): Linguistic and Literary Considerations|journal=Economic Botany|volume=64|issue=2|pages=109–123|date=2010|doi=10.1007/s12231-010-9115-2|last2=Bothmer|first2=Roland|last3=Poulsen|first3=Gert|last4=Branca|first4=Ferdinando|hdl=10568/121874 |s2cid=2771884|hdl-access=free}} Broccoli has its origins in primitive cultivars grown in the Roman Empire and was most likely improved via artificial selection in the southern Italian Peninsula or in Sicily.{{cite book|last=Nonnecke|first=Ib|title=Vegetable Production|publisher=Springer-Verlag New York, LLC|date=November 1989|page=394|isbn=978-0-442-26721-6|url=https://books.google.com/books?id=H7i8QJw8BJsC&pg=PA394|access-date=6 October 2020|archive-date=9 March 2023|archive-url=https://web.archive.org/web/20230309051152/https://books.google.com/books?id=H7i8QJw8BJsC&pg=PA394|url-status=live}}{{cite journal|last1=Stansell|first1=Zachary |last2=Björkman|first2=Thomas|date=1 October 2020|title=From landrace to modern hybrid broccoli: the genomic and morphological domestication syndrome within a diverse B. oleracea collection|journal=Horticulture Research|language=en|volume=7|issue=1|page=159|doi=10.1038/s41438-020-00375-0|pmid=33082966|pmc=7528014|bibcode=2020HorR....7..159S |issn=2052-7276|s2cid=224724369}}{{cite journal|last1=Stansell|first1=Zachary|last2=Hyma|first2=Katie|last3=Fresnedo-Ramírez|first3=Jonathan|last4=Sun|first4=Qi|last5=Mitchell|first5=Sharon|last6=Björkman|first6=Thomas|last7=Hua|first7=Jian|date=1 July 2018|title=Genotyping-by-sequencing of Brassica oleracea vegetables reveals unique phylogenetic patterns, population structure and domestication footprints|journal=Horticulture Research|language=en|volume=5|issue=1|page=38|doi=10.1038/s41438-018-0040-3|pmid=29977574|pmc=6026498|bibcode=2018HorR....5...38S |issn=2052-7276}} Broccoli was spread to northern Europe by the 18th century and brought to North America in the 19th century by Italian immigrants. After the Second World War, the breeding of the United States and Japanese F1 hybrids increased yields, quality, growth speed, and regional adaptation, which produced the cultivars commonly grown since then: 'Premium Crop', 'Packman', and 'Marathon'.
Description
Broccoli is an annual cruciferous plant which can grow up to {{cvt|60|–|90|cm|in|}} tall.{{cite web |publisher=Encyclopædia Britannica |title=Broccoli, plant |url=https://www.britannica.com/plant/broccoli|date=3 March 2025 |access-date=15 April 2025}}
Broccoli inflorescence grows at the end of a central, edible stem and is dark green. Violet, yellow, or even white heads have been created, but these varieties are rare. The flowers are yellow with four petals.
The growth season for broccoli is 14–15 weeks. Broccoli is collected by hand immediately after the head is fully formed yet the flowers are still in their bud stage. The plant develops numerous small "heads" from the lateral shoots which can be harvested later.
Varieties
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 {{convert|10|to(-)|20|cm|in|0|adj=on}} green heads and thick stalks. It is a cool-season annual crop. Sprouting broccoli (white or purple) has a larger number of heads with many thin stalks.{{cite web|title=Broccoli|url=https://www.rhs.org.uk/advice/grow-your-own/vegetables/broccoli|website=Royal Horticultural Society|access-date=24 March 2020|archive-date=24 March 2020|archive-url=https://web.archive.org/web/20200324233555/https://www.rhs.org.uk/advice/grow-your-own/vegetables/broccoli|url-status=live}} Purple cauliflower or violet cauliflower is a type of broccoli grown in Europe and North America. It has a head shaped like cauliflower but consists of many tiny flower buds. Sometimes, but not always, it has a purple cast to the tips of the flower buds. Purple cauliflower may also be white, red, green, or other colors.{{citation|last=Branca|first=Ferdinando|title=Cauliflower and Broccoli|date=2008|work=Vegetables I: Asteraceae, Brassicaceae, Chenopodicaceae, and Cucurbitaceae|pages=151–186|editor1-last=Prohens|editor1-first=Jaime|editor2-last=Nuez|editor2-first=Fernando|series=Handbook of Plant Breeding|volume=1|place=New York, NY|publisher=Springer|language=en|doi=10.1007/978-0-387-30443-4_5|isbn=978-0-387-30443-4}}
Beneforté is a variety of broccoli containing 2–3 times more glucoraphanin and produced by crossing broccoli with a wild Brassica variety, Brassica oleracea var villosa.{{cite web|title=British research leads to UK-wide launch of Beneforté broccoli|url=https://quadram.ac.uk/beneforte_uk_wide/|website=Quadram Institute|access-date=24 March 2020|date=25 June 2012}}
Other cultivar groups of ''Brassica oleracea''
{{Main|Brassica oleracea#Cultivar groups}}
Other cultivar groups of Brassica oleracea include cabbage (Capitata Group), cauliflower and Romanesco broccoli (Botrytis Group), kale (Acephala Group), collard (Viridis Group), kohlrabi (Gongylodes Group), Brussels sprouts (Gemmifera Group), and kai-lan (Alboglabra Group).{{cite book|last1=Dixon|first1=G.R.|date=2007|title=Vegetable brassicas and related crucifers|isbn=978-0-85199-395-9|publisher=CABI|location=Wallingford}} As these groups are the same species, they readily hybridize: for example, broccolini or "Tenderstem broccoli" is a cross between broccoli and kai-lan.{{Cite journal|last1=Stansell|first1=Zachary|last2=Farnham|first2=Mark|last3=Björkman|first3=Thomas|date=2019|title=Complex Horticultural Quality Traits in Broccoli Are Illuminated by Evaluation of the Immortal BolTBDH Mapping Population|journal=Frontiers in Plant Science|language=en|volume=10|page=1104|doi=10.3389/fpls.2019.01104|pmid=31620146|pmc=6759917|issn=1664-462X|doi-access=free}} Broccoli cultivars form the genetic basis of the "tropical cauliflowers" commonly grown in South and Southeastern Asia, although they produce a more cauliflower-like head in warmer conditions.{{cite journal|last1=Bjorkman|first1=T.|last2=Pearson|first2=K.

Production
In 2023, global production of broccoli (combined for production reports with cauliflowers) was 26.5 million tonnes, with China and India together accounting for 65% of the world total (table). Secondary producers, each having about one million tonnes or less annually, were the United States, Mexico, and Spain.
In the United States, broccoli is grown year-round in California – which produced 92% of the crop nationally – with 95% of the total crop produced for fresh sales in 2018.{{cite web|title=Broccoli|url=https://www.agmrc.org/commodities-products/vegetables/broccoli|publisher=Agricultural Marketing Resource Center, US Department of Agriculture|date=1 June 2018|access-date=27 June 2019|archive-date=1 July 2019|archive-url=https://web.archive.org/web/20190701120609/https://www.agmrc.org/commodities-products/vegetables/broccoli|url-status=live}}

Nutrition
Raw broccoli is 89% water, 7% carbohydrates, 3% protein, and contains negligible fat (table). A {{convert|100|g|oz|frac=2|abbr=off|adj=on}} reference amount of raw broccoli provides {{convert|141|kJ|kcal|abbr=off}} of food energy and is a rich source (20% or higher of the Daily Value, DV) of vitamin C (99% DV) and vitamin K (85% DV) (table). Raw broccoli also contains moderate amounts (10–19% DV) of several B vitamins and the dietary mineral potassium, whereas other micronutrients are low in content (less than 10% DV). Broccoli contains the dietary carotenoid, beta-carotene.{{cite journal |last1=Farnham |first1=Mark W. |last2=Kopsell |first2=Dean A. |title=Importance of Genotype on Carotenoid and Chlorophyll Levels in Broccoli Heads |journal=HortScience |date=Aug 2009 |volume=44 |issue=5 |page=1248-1253|doi=10.21273/HORTSCI.44.5.1248 |url=https://journals.ashs.org/hortsci/view/journals/hortsci/44/5/article-p1248.xml|access-date=18 October 2023}} [https://journals.ashs.org/hortsci/downloadpdf/journals/hortsci/44/5/article-p1248.xml PDF]

{{See also|List of broccoli dishes}}
Boiling substantially reduces the levels of broccoli glucosinolates, while other cooking methods, such as steaming, microwaving, and stir-frying, have no significant effect on glucosinolate levels.
Taste
The perceived bitterness of cruciferous vegetables, such as broccoli, results from glucosinolates and their hydrolysis products, particularly isothiocyanates and other sulfur-containing compounds.{{cite journal | last1=Bell | first1=Luke | last2=Oloyede | first2=Omobolanle O. | last3=Lignou | first3=Stella | last4=Wagstaff | first4=Carol | last5=Methven | first5=Lisa | title=Taste and flavor perceptions of glucosinolates, isothiocyanates, and related compounds | journal=Molecular Nutrition and Food Research | volume=62 | issue=18 | date=2018-04-30 | issn=1613-4125 | pmid=29578640 | doi=10.1002/mnfr.201700990 | page=1700990| s2cid=206265098 | url=https://centaur.reading.ac.uk/76654/1/mnfr.201700990.pdf }} Preliminary research indicates that genetic inheritance through the gene TAS2R38 may be responsible in part for bitter taste perception in broccoli.{{cite journal|pmid=24025627|title=Human bitter perception correlates with bitter receptor messenger RNA expression in taste cells|vauthors=Lipchock SV, Mennella JA, Spielman AI, Reed DR|journal=Am J Clin Nutr|date=2013|volume=98|issue=4|pages=1136–43|doi=10.3945/ajcn.113.066688|pmc=3778862}}
