Celery leaves are pinnate to bipinnate with rhombic leaflets 3–6 centimetres (1–2+1⁄2 inches) long and 2–4 cm (1–1+1⁄2 in) broad. The flowers are creamy-white, 2–3 mm (3⁄32–1⁄8 in) in diameter, and are produced in dense compound umbels. The seeds are broad ovoid to globose, 1.5–2 mm (1⁄16–5⁄64 in) long and wide. Modern cultivars have been selected for either solid petioles, leaf stalks, or a large hypocotyl.[2] A celery stalk readily separates into "strings" which are bundles of angular collenchyma cells exterior to the vascular bundles.[3]
First attested and printed in English as "sellery" by John Evelyn in 1664,[4] the modern English word "celery" derives from the French céleri, in turn from Italian seleri, the plural of selero, which comes from Late Latin selinon,[5] the latinisation of the Ancient Greek: σέλινον, romanized: selinon, "celery".[6][7] The earliest attested form of the word is the Mycenaean Greek se-ri-no, written in Linear B syllabic script.[8]
The species Apium graveolens was described by Carl Linnaeus in Volume One of his Species Plantarum in 1753.[9] Cultivated celery has been called Apium graveolens var. dulce or Apium graveolens Dulce Group.[1]
The plants are raised from seed, sown either in a hot bed or in the open garden according to the season of the year, and, after one or two thinnings and transplantings, they are, on attaining a height of 15–20 cm (6–8 in), planted out in deep trenches for convenience of blanching, which is effected by earthing up to exclude light from the stems. Development of self-blanching varieties of celery, which do not need to be earthed up, dominate both the commercial and amateur market.[10]
Celery was first grown as a winter and early spring vegetable.[11] It was considered a cleansing tonic to counter the deficiencies of a winter diet based on salted meats without fresh vegetables.[11] By the 19th century, the season for celery in England had been extended, to last from the beginning of September to late in April.[12]
In North America, commercial production of celery is dominated by the cultivar called 'Pascal' celery.[2] Gardeners can grow a range of cultivars, many of which differ from the wild species, mainly in having stouter leaf stems. They are ranged under two classes, white and red. The stalks grow in tight, straight, parallel bunches, and are typically marketed fresh that way. They are sold without roots and only a small amount of green leaf remaining.[13]
The stalks can be eaten raw, or as an ingredient in salads, or as a flavouring in soups, stews, and pot roasts.[14]

Harvesting occurs when the average size of celery in a field is marketable; due to extremely uniform crop growth, fields are harvested only once. The petioles and leaves are removed and harvested; celery is packed by size and quality (determined by colour, shape, straightness and thickness of petiole, stalk and midrib[clarification needed] length and absence of disease, cracks, splits, insect damage and rot). During commercial harvesting, celery is packaged into cartons which contain between 36 and 48 stalks and weigh up to 27 kg (60 lb).[15] Under optimal conditions, celery can be stored for up to seven weeks from 0–2 °C (32–36 °F). Inner stalks may continue growing if kept at temperatures above 0 °C (32 °F). Shelf life can be extended by packaging celery in anti-fogging, micro-perforated shrink wrap.[16] Freshly cut petioles of celery are prone to decay, which can be prevented or reduced through the use of sharp blades during processing, gentle handling, and proper sanitation.[17]
Celery stalk may be preserved through pickling by first removing the leaves, then boiling the stalks in water before finally adding vinegar, salt, and vegetable oil.[18]
In the past, restaurants used to store celery in a container of water with powdered vegetable preservative, but it was found that the sulfites in the preservative caused allergic reactions in some people.[19] In 1986, the U.S. Food and Drug Administration banned the use of sulfites on fruits and vegetables intended to be eaten raw.[20]
Celery is eaten around the world as a vegetable. In North America and Europe the crisp petiole (leaf stalk) is used. In Europe the hypocotyl is also used as a root vegetable. The leaves are strongly flavoured and are used less often, either as a flavouring in soups and stews or as a dried herb. Celery, onions, and bell peppers are the "holy trinity" of Louisiana Creole and Cajun cuisine. Celery, onions, and carrots make up the French mirepoix, often used as a base for sauces and soups. Celery is a staple in many soups.[21] It is used in the Iranian stew khoresh karafs.
Celery leaves are frequently used in cooking to add a mild spicy flavour to foods, similar to, but milder than black pepper. Celery leaves are suitable dried and sprinkled on baked, fried or roasted fish or meats, or as part of a blend of fresh seasonings suitable for use in soups and stews. They may also be eaten raw, mixed into a salad or as a garnish.[22]
In temperate countries, celery is also grown for its seeds. Actually very small fruit, these "seeds" yield a valuable essential oil that is used in the perfume industry. The oil contains the chemical compound apiole. Celery seeds can be used as flavouring or spice, either as whole seeds or ground.[23]
Celery seeds can be ground and mixed with salt to produce celery salt. Celery salt can be made from an extract of the roots or by using dried leaves. Celery salt is used as a seasoning, in cocktails (commonly to enhance the flavour of Bloody Mary cocktails), on the Chicago-style hot dog, and in Old Bay Seasoning. Similarly, combinations of celery powder and salt are used to flavour and preserve cured pork[24] and other processed meats as an alternative to industrial curing salt.[25] The naturally occurring nitrates in celery work synergistically with the added salt to cure food.[26]
In 2019, a trend of drinking celery juice was reported in the United States, based on "detoxification" claims posted on a blog. The claims have no scientific basis, but the trend caused a sizable spike in celery prices.[27][28]

Raw celery is 95% water, 3% carbohydrates, 0.7% protein, and contains negligible fat (table). A 100-gram (3+1⁄2-ounce) reference serving provides 16 calories of food energy, and is a rich source of selenium and vitamin K, providing 73% and 24% of the Daily Value, respectively, with no other micronutrients in significant content (table).
Celery is among a small group of foods that may provoke allergic reactions; for people with celery allergy, exposure can cause potentially fatal anaphylactic shock.[31] Cases of allergic reaction to ingestion of celery root have also been reported in pollen-sensitive individuals resulting in gastrointestinal disorders and other symptoms, although in most cases, celery sensitivity is not considered clinically significant.[32] In the European Union and the United Kingdom, foods that contain or may contain celery, even in trace amounts, must be clearly marked.[33]
The Apium graveolens plant has an OPALS allergy scale rating of 4 out of 10, indicating moderate potential to cause allergic reactions, exacerbated by over-use of the same plant throughout a garden.[34] Celery has caused skin rashes and cross-reactions with carrots and ragweed.[34]
The main chemicals responsible for the aroma and taste of celery are butylphthalide and sedanolide.[35]
Daniel Zohary and Maria Hopf[36] note that celery leaves and inflorescences were part of the garlands found in the tomb of pharaoh Tutankhamun (died 1323 BC), and celery mericarps dated to the seventh century BC were recovered in the Heraion of Samos. However, they note A. graveolens grows wild in these areas, it is hard to decide whether these remains represent wild or cultivated forms." Only by classical antiquity is it thought that celery was cultivated.[37]
M. Fragiska mentions an archeological find of celery dating to the 9th century BC, at Kastanas; however, the literary evidence for ancient Greece is far more abundant. In Homer's Iliad, the horses of the Myrmidons graze on wild celery that grows in the marshes of Troy, and in Odyssey, there is mention of the meadows of violet and wild celery surrounding Calypso's Cave.[38]
In the Capitulary of Charlemagne, compiled c. 800, apium appears, as does olisatum, or alexanders, among medicinal herbs and vegetables the Frankish emperor desired to see grown.[39] At some later point in medieval Europe, celery displaced alexanders.[40]
The name "celery" retraces the plant's route of successive adoption in European cooking, as the English "celery" (1664) is derived from the French céleri coming from the Lombard term, seleri, from the Latin selinon, borrowed from Greek.[41]
Celery's late arrival in the English kitchen is an end-product of the long tradition of seed selection needed to reduce the sap's bitterness and increase its sugars. By 1699, John Evelyn could recommend it in his Acetaria. A Discourse of Sallets: "Sellery, apium Italicum, (and of the Petroseline Family) was formerly a stranger with us (nor very long since in Italy) is a hot and more generous sort of Macedonian Persley or Smallage... and for its high and grateful Taste is ever plac'd in the middle of the Grand Sallet, at our Great Men's tables, and Praetors feasts, as the Grace of the whole Board".[42]
Celery makes a minor appearance in colonial American gardens; its culinary limitations are reflected in the observation by the author of A Treatise on Gardening, by a Citizen of Virginia that it is "one of the species of parsley".[43] Its first extended treatment in print was in Bernard M'Mahon's American Gardener's Calendar (1806).[44]
After the mid-19th century, continued selections for refined crisp texture and taste brought celery to American tables, where it was served in celery vases to be salted and eaten raw. Celery was so popular in the United States during the 19th century and early 20th century that the New York Public Library's historical menu archive shows that it was the third most popular dish in New York City menus during that time, behind only coffee and tea. In those days, celery cost more than caviar, as it was difficult to cultivate. There were also many varieties of celery back then that are no longer around because they are difficult to grow and do not ship well.[45]

A chthonian symbol among the ancient Greeks, celery was said to have sprouted from the blood of Kadmilos, father of the Cabeiri, chthonian divinities celebrated in Samothrace, Lemnos, and Thebes.[citation needed] The spicy odor and dark leaf colour encouraged this association with the cult of death. In classical Greece, celery leaves were used as garlands for the dead, and the wreaths of the winners at the Isthmian Games were first made of celery before being replaced by crowns made of pine. According to Pliny the Elderin[46] Achaea, the garland worn by the winners of the sacred Nemean Games was also made of celery.[38] The Ancient Greek colony of Selinous (Ancient Greek: Σελινοῦς, Selinous), on Sicily, was named after wild parsley that grew abundantly there; Selinountian coins depicted a parsley leaf as the symbol of the city.[citation needed]
The fifth incarnation of the Doctor in the British science fiction show Doctor Who wore a decorative stick of celery on his lapel. In the show, the Doctor would state that the celery would turn purple when exposed to certain gases in the praxis range, in which case he would eat the celery. Ironically, Peter Davison did not like celery.
