Cabbage

• 1. Introduction

  ›

  Cabbage has been at the human table for longer than written history can fully account for, and the word itself carries ancient weight. It descends from the Picard dialect of Old French, caboche, meaning simply "head". That plain, direct name points to something that made cabbage stand apart from other leafy plants: its tendency to fold inward, leaf by leaf, forming a dense, compact globe. This was a genuinely unusual quality in the ancient world, and it drew attention. How did a coastal cliff plant become a staple food on nearly every continent? Why did Roman senators debate whether it belonged at their tables while poor Parisians survived lean winters on almost nothing else? And what does a Guinness World Record of 62.71 kilograms tell us about just how far selective breeding has pushed this modest vegetable?

• 2. Ancient Roots and Spread

  ›

  Nonheading cabbages and kale were probably the first forms to be domesticated, before 1000 BC, possibly by the Celts of central and western Europe, though recent linguistic and genetic evidence points toward a Mediterranean origin for cultivated brassicas as a whole. The ancient Greeks knew headed cabbage as krambe and the open, leafy variety as raphanos. Theophrastus mentioned their cabbage varieties, though whether those plants resembled modern cabbage or another brassica entirely is still uncertain. The Romans used two words: brassica for the headed form and caulis for the open, leafy kale-like variety.

  Chrysippus of Cnidos composed a full treatise on cabbage, which Pliny the Elder knew of but which has not survived. Pliny himself catalogued seven varieties by name, including Pompeii cabbage, Cumae cabbage, and Sabellian cabbage. His description of the Pompeii variety is precise: taller than others, with a thick stock near the root, sparser and narrower leaves, and a tenderness that was considered its most prized quality. That same variety was mentioned by Columella in De Re Rustica.

  Cato the Elder, who championed a simple Republican life, ate cabbage cooked or raw with vinegar and declared it superior to all other vegetables. He distinguished three varieties and wrote instructions for its medicinal use, including the striking claim that infants might be rinsed in the urine of someone who ate cabbage. Pliny records that the Greeks also believed cabbages and grapevines were mutually hostile, and that cabbage planted too close to a vine would transfer its odor to the grapes. That sense of antipathy, he notes, has survived into modern Mediterranean practice.

  By early Roman times, Egyptian artisans and children were eating cabbage and turnips alongside a wide variety of other vegetables. Ptolemaic Egyptians called the crop gramb, a word shaped by the Greek krambe, which reflected the Macedonian roots of the Ptolemaic dynasty.

  ›

  The ancient Greeks recommended cabbage as a laxative and used its juice as an antidote for mushroom poisoning. They also applied it in eye salves and as a liniment for bruises. Ancient Egyptians ate cooked cabbage at the start of meals specifically to blunt the effects of wine, a practice that connected to the wider Mediterranean belief that cabbage counteracted drunkenness.

  In the first century AD, Dioscorides identified two kinds of coleworts with medical uses, the cultivated and the wild, and his opinions were still being paraphrased in herbals as late as the 17th century. The Romans similarly attributed broad healing powers to cabbage, claiming relief from gout, headaches, and the symptoms of poisonous mushroom ingestion.

  British folk medicine found its own applications. During the First World War, the supposed cooling properties of cabbage leaves were used as a treatment for trench foot. Poultices of mashed cabbage and cabbage juice were applied for boils, warts, pneumonia, appendicitis, and ulcers. Other recorded folk uses in European herbalism included treatments for rheumatism, sore throat, hoarseness, colic, and melancholy.

  By the late 20th century, most of these traditional uses had faded from European medical literature. Researchers today are studying phytochemicals in cabbage, including isothiocyanates, sulforaphane, and other glucosinolates, but as of 2024 there remains insufficient evidence that consuming cabbage compounds lowers cancer risk. A 2021 study did suggest cabbage may have value in managing type 2 diabetes, pointing toward possible directions for ongoing work.

• 4. Medieval Tables and Royal Records

  ›

  Manuscript illuminations from the High Middle Ages show cabbage appearing prominently in cuisine across Europe, a visible mark of how central the vegetable had become to everyday life. The seed list of purchases for King John II of France, held captive in England in 1360, includes cabbage seeds, a detail that confirms it was standard even in high-status households.

  But cabbage was equally the food of poverty. In the lean year of 1420, a chronicler known as the Bourgeois of Paris wrote that poor people ate no bread, only cabbages and turnips and such dishes, without any bread or salt. That stark account captures the dual identity cabbage would hold for centuries: present at royal tables and at the margins of survival in the same era.

  At the end of antiquity, cabbage appears in De observatione ciborum, written by Anthimus, a Greek doctor at the court of Theodoric the Great. Charlemagne's Capitulare de villis, composed between 771 and 800 AD, listed cabbage among the vegetables to be cultivated on the royal estates, evidence that administrations actively managed its production.

  When round-headed cabbages arrived in 14th-century England, they were called cabaches and caboches, words taken directly from Old French. A recipe from that period begins with the instruction to take cabbages, quarter them, and seethe them in good broth, suggesting the tightly headed form was already familiar. French naturalist Jean Ruel made what is considered the first explicit written mention of head cabbage in his 1536 botanical treatise De Natura Stirpium, calling it capucos coles, or head-coles.

• 5. Savoy, Sauerkraut, and the Sea

  ›

  German gardeners developed the savoy cabbage during the 16th century. Its crimped, curly leaves and mild flavor distinguished it from the smooth-leafed varieties that had dominated European cultivation. By the 17th and 18th centuries, cabbage had become a staple food across Germany, England, Ireland, and Russia, where pickled forms were frequently eaten through the long winter months.

  Sauerkraut played a practical role beyond the kitchen. Dutch, Scandinavian, and German sailors used it during long sea voyages to prevent scurvy. The fermentation process preserved the vegetable and its vitamin C content in a form that could survive weeks at sea. European sailors also brought fresh cabbage on board for the same purpose, creating a direct link between a preserved vegetable and the ability to complete ocean crossings.

  Jacques Cartier brought cabbage to the Americas in 1541-42. Despite a lack of written evidence placing it there until the mid-17th century, it was probably planted by early English colonists. By the 18th century, both colonists and Native American Indians were cultivating it widely. Cabbage seeds reached Australia in 1788 with the First Fleet and were planted that same year on Norfolk Island. The vegetable became a favorite of Australians by the 1830s, regularly appearing at the Sydney Markets.

  In India, cabbage was one of several vegetable crops introduced by Portuguese traders who established trade routes from the 14th to the 17th centuries. Carl Peter Thunberg reported that cabbage was not yet known in Japan as late as 1775, placing a useful boundary on how recent its arrival there was. The open-air cabbage market in Brno, Czech Republic, known as the Zelný trh, has been operating since 1325, a record of continuous commercial activity that predates Cartier's voyage to the Americas by more than two centuries.

• 6. Biology and Cultivation

  ›

  Cabbage seedlings begin with a thin taproot and heart-shaped cotyledons. The initial leaves form a rosette of 7 to 15 leaves, each measuring roughly 25-35 cm by 20-30 cm. After that stage, leaves with shorter stems develop and the head forms as they cup inward. About 90% of the root mass stays in the upper 20-30 cm of soil, though some lateral roots can reach as deep as 2 m.

  The plant's flower is precise in its structure: four petals arranged in a perpendicular pattern, four sepals, six stamens, and a two-celled superior ovary. Two of the six stamens have shorter filaments than the others. Self-pollination is impossible; insects must cross-pollinate the plants. When grown for seed, cabbages must be kept isolated from other B. oleracea subspecies to prevent cross-pollination, though closely related species such as B. rapa and B. napus do not readily cross-pollinate with them.

  Temperatures between 4 and 24 degrees Celsius prompt the best growth. Extended periods outside that range can trigger premature bolting. The transition from juvenile to adult plant happens when the stem diameter reaches about 6 mm, a specific threshold that determines when flowering can be induced by cold. Seedlings typically emerge in 4-6 days from seeds planted at a soil temperature between 20 and 30 degrees Celsius. Early varieties reach maturity in about 70 days from planting; late varieties take about 120 days.

  Cabbage can be stored longest at -1 to 2 degrees Celsius with humidity at 90-100%, conditions that allow up to six months of longevity. Under less ideal conditions, it can still last up to four months, a durability that has made it practical for storage across climates where fresh produce was otherwise scarce in winter.

• 7. Pests and Pathogens

  ›

  The diamondback moth (Plutella xylostella) has caused crop losses of up to 90 percent in India in fields not treated with insecticide, a figure that conveys the severity of what cabbage growers face. The caterpillar stage of the small cabbage white butterfly (Pieris rapae), known in the United States as the imported cabbage worm, is a major pest across most countries. The large white butterfly (Pieris brassicae) is prevalent in eastern Europe, while the cabbage looper (Trichoplusia ni) is considered voracious in North America, where it also contaminates plants with frass.

  Bacterial black rot, caused by Xanthomonas campestris, produces chlorotic and necrotic lesions starting at the leaf margins, leading to wilting. Clubroot, caused by Plasmodiophora brassicae, swells the roots into club-like shapes. The fungi Alternaria brassicae and A. brassicicola cause dark leaf spots and can persist in infected plant debris on the soil surface for up to twelve weeks after harvest, spreading as both seedborne and airborne pathogens.

  Nutrient deficiencies compound these pressures. Cabbage is prone to shortfalls of boron, calcium, phosphorus, and potassium, each of which produces distinct symptoms. Internal tip burn causes the margins of interior leaves to brown while outer leaves look normal. Necrotic spot produces oval sunken marks a few millimeters across, often grouped near the midrib. Pepper spot creates tiny black dots between the leaf veins that can multiply during storage.

  The mustard leaf beetle (Phaedon cochleariae) makes a revealing choice: it prefers cabbage over its natural host plants because cabbage contains higher quantities of glucosinolates, the same sulfur compounds that give cabbage its characteristic flavor. That preference illustrates how a feature of cabbage that humans value can also attract the pests that threaten the crop.

• 8. Global Production and Kitchen

  ›

  In 2023, world cabbage production reached 74 million tonnes. China led with 48% of the total, followed by substantial output from India, Russia, and South Korea. Russia also holds the highest per capita consumption of any country, at 20 kg per person annually. Belgium follows at 4.7 kg, the Netherlands at 4.0 kg, and Americans consume 8.6 lb per capita each year.

  Raw cabbage is 92% water, with 6% carbohydrates and 1% protein. In a 100 g serving, it supplies 25 calories and provides 41% of the Daily Value for vitamin C and 63% for vitamin K. It is also a moderate source of folate at 11% of the Daily Value.

  Glucosinolates, the sulfur-containing compounds concentrated most heavily in the seeds and decreasing as vegetative tissue ages, are responsible for cabbage's flavor. Overcooking converts these compounds into hydrogen sulfide gas, producing the pungent odor that gives boiled cabbage its poor reputation. The trisaccharide raffinose, which the human small intestine cannot break down but which bacteria in the large intestine ferment, is the source of the intestinal gas associated with cabbage consumption.

  In Poland, cabbage features in bigos (a dish combining cabbage, sauerkraut, meat, and wild mushrooms), gołąbki (stuffed cabbage), and pierogi. The British dish bubble and squeak is made primarily with leftover potato and boiled cabbage. In the United States, cabbage is used most heavily for coleslaw production. Sultan Selim III of Istanbul once wrote a tongue-in-cheek ode to the vegetable, declaring that without cabbage, a halva feast was not complete, a reminder that cabbage has found admirers in unexpected quarters throughout its long history.
