Spinach

Spinach (Spinacia oleracea) is an annual herbaceous plant in the Amaranthaceae family, cultivated worldwide as a leafy green vegetable for its tender, nutrient-dense leaves.^[1] Native to southwestern Asia, where it was first domesticated in ancient Persia over 2,000 years ago, spinach spread to Europe via Arab traders in the Middle Ages and reached the Americas with European colonists by the 17th century.^[2]^[3] It thrives as a cool-season crop, forming rosettes of oblong to arrow-shaped leaves that are harvested young for fresh consumption in salads or mature for cooking in soups, sautés, and side dishes.^[4] Varieties are broadly classified into smooth-leaf types, favored for mechanical harvesting and processing, and savoy types with crinkled leaves, preferred for home gardens and fresh markets due to their texture, flavor, and lower oxalic acid content.^[2] Nutritionally, spinach is low in calories (about 7 per cup of raw leaves) yet exceptionally rich in vitamins A, C, and K, folate, iron, calcium, potassium, and antioxidants like lutein and beta-carotene, making it a staple in diets promoting eye health, bone strength, and overall cardiovascular wellness.^[5]^[6] Despite its benefits, spinach contains oxalates that can inhibit mineral absorption, and it requires careful cultivation to avoid bolting in warm conditions or contamination risks like E. coli.^[7]

Etymology and Taxonomy

Etymology

The English word "spinach" entered the language in the late 14th century, derived from Middle English spinach or spinage, which traces back to Anglo-Norman spinache and Old French espinache or espinoches.^[8]^[9] This, in turn, stems from Medieval Latin spinagium or spinachium, ultimately originating from Arabic isbinakh (إِسْفَانَاخ), a borrowing from Persian aspānāḵ (اسپاناخ), referring to a garden vegetable with thick, succulent leaves.^[8]^[9] The term's journey reflects ancient trade and cultural exchanges along the Silk Road and Mediterranean routes, where the plant itself spread from its Persian homeland.^[8] In Romance languages, the word evolved similarly due to these historical influences. French adopted épinards from the Old French root, while Spanish uses espinacas, both retaining phonetic echoes of the Arabic intermediary.^[8] Italian spinaci and Portuguese espinafre show parallel adaptations, underscoring the vegetable's dissemination through Moorish Spain and medieval European markets.^[9] Early English variations included spellings like spynache, spynage, or spinarge in 15th-century texts, gradually standardizing to "spinach" by the 16th century.^[8] Regional dialects in Britain and later colonial contexts sometimes retained archaic forms like "spinage," preserving the word's phonetic evolution amid local linguistic shifts.^[9]

Taxonomy

Spinach, scientifically known as Spinacia oleracea L., belongs to the kingdom Plantae, phylum Tracheophyta, class Magnoliopsida, order Caryophyllales, family Amaranthaceae, genus Spinacia, and species S. oleracea.^[10] The genus Spinacia comprises three species: the cultivated S. oleracea and the wild relatives S. tetrandra and S. turkestanica.^[11] The family Amaranthaceae encompasses the former family Chenopodiaceae, which was merged into it under the Angiosperm Phylogeny Group (APG) II classification system in 2003 based on molecular phylogenetic evidence demonstrating their close relationship.^[12] Within the species S. oleracea, taxonomic varieties include the cultivated spineless form S. oleracea var. oleracea and the spiny-seeded variety S. oleracea var. spinosa (Moench), which is considered a wild or ancestral relative with morphological adaptations such as prickly fruits.^[13] Numerous cultivars have been developed from these varieties, primarily selected for traits like leaf texture (smooth or savoy) and seed characteristics, though they remain classified under the single species S. oleracea.^[14] Spinacia oleracea shares genetic affinities with other Amaranthaceae members, including beets (Beta vulgaris) and quinoa (Chenopodium quinoa), reflecting common ancestry within the Caryophyllales order.^[15] Its evolutionary divergence traces back to wild ancestors in central Asia, particularly regions like Persia (modern-day Iran), where progenitor populations exhibited greater genetic diversity before domestication narrowed variation in cultivated lines.^[16]

Botanical Description

Physical Characteristics

Spinach (Spinacia oleracea) is a glabrous, annual herb belonging to the Amaranthaceae family, characterized by its basal rosette growth form in the vegetative stage.^[1] The plant develops from a short, thick taproot that anchors the rosette and supports nutrient uptake, with the root system remaining relatively shallow overall.^[2] Stems are smooth and green, typically erect or spreading, reaching up to 30 cm in height during leaf production, though they can elongate further upon bolting.^[17]^[18] The leaves emerge in a dense rosette arrangement, featuring broad, simple blades that are ovate to triangular or arrow-shaped, often with auriculate bases where "earlobes" form at the petiole junction.^[1] They measure 2–30 cm in length and 1–15 cm in width, with fleshy texture and entire margins; surfaces may be smooth and flat or crinkled as in savoy types.^[17] Petioles are prominent, supporting the blade and contributing to the plant's overall compactness.^[10] Spinach is primarily dioecious, with male and female flowers occurring on separate plants in small, inconspicuous axillary clusters, though occasional monoecious or hermaphroditic individuals may occur.^[1]^[14] The flowers are greenish-yellow, measuring 3–4 mm in diameter, and lack showy petals, consisting instead of 4–5 tepals.^[17] Female flowers develop into dry, indehiscent utricles enclosed in spiny or smooth husks, forming lumpy clusters 5–10 mm across that contain 2–4 seeds each.^[19]^[14]

Growth and Life Cycle

Spinach (Spinacia oleracea) is primarily an annual plant, completing its life cycle within one growing season, although it can exhibit biennial behavior in temperate climates where it overwinters as a rosette and bolts the following spring.^[2] The plant progresses through two main developmental stages: a vegetative rosette phase, during which leaves form the primary harvestable portion, and a reproductive phase marked by bolting, or the elongation of a central flowering stalk.^[20] This life cycle is adapted to cool-season conditions, with the vegetative stage optimized for leaf production before environmental cues trigger reproduction. Germination begins when seeds are sown in soil temperatures between 7–20°C (45–68°F), typically taking 3–10 days under optimal cool conditions, though it can extend to three weeks at lower temperatures around 10°C (50°F).^[21] Following emergence, the plant enters vegetative growth, developing a rosette of leaves that reaches harvestable maturity in 40–50 days, depending on variety and environmental factors.^[22] During this period, the focus is on leaf expansion, with plants producing alternate, simple, ovate to triangular leaves that serve as the edible component. Bolting is induced by long-day photoperiods (typically over 14 hours of daylight) or exposure to heat above 24°C (75°F), which shifts resources from leaf growth to stem elongation and flower initiation, often reducing leaf quality and edibility.^[23] Reproduction in spinach is wind-pollinated, with the dioecious nature promoting outcrossing and genetic diversity through cross-pollination between male and female plants.^[14] Seed production generally requires vernalization, a cold treatment of 5–10°C (41–50°F) for 1–5 weeks during the juvenile stage, which promotes flowering in the subsequent season if the plant survives overwintering.^[23] Under non-vernalized conditions, such as in short-day or warm environments, bolting may occur prematurely without seed set, limiting the plant to its annual habit.^[24]

History

Origins and Domestication

Spinach (Spinacia oleracea) is native to central and western Asia, with its wild relatives Spinacia tetrandra and Spinacia turkestanica distributed across regions including Transcaucasia, Kurdistan, and areas around the Caspian Sea extending into Central and South Asia.^[25] These wild species, which grow in arid and semi-arid environments, provided the genetic foundation for domestication, with S. turkestanica identified as the most likely direct progenitor based on phylogenetic analyses.^[26] The plant's natural range encompasses diverse habitats from the Iranian plateau to the steppes of Uzbekistan and Turkmenistan, reflecting adaptations to varying climates in these areas.^[27] Genetic studies indicate a domestication bottleneck around 2,000 years ago, with cultivated spinach diverging from S. turkestanica populations in Central Asia, particularly those in Uzbekistan and Tajikistan; traditional accounts attribute initial domestication to ancient Persia (modern-day Iran).^[26] This process transformed the plant from a weedy perennial into an annual leafy crop suited for human consumption, though the exact timeline aligns with broader agricultural developments in the region rather than earlier Bronze Age estimates.^[27] Archaeological and genetic data support early use in Central Asia as part of local diets.^[25] In ancient Persia, the plant's name derives from "aspānāḵ," highlighting its linguistic and cultural roots in the region.^[25] Initially, spinach was primarily utilized as a medicinal plant in ancient Persian and early Islamic herbal traditions, employed to alleviate fatigue, inflammation, and digestive issues due to its cooling properties.^[28] Over time, these therapeutic applications evolved into broader culinary adoption as a nutritious green, though medicinal uses persisted in traditional systems across Asia.^[29]

Historical Cultivation and Spread

Spinach, originating from domestication in ancient Persia around 2,000 years ago, spread eastward to China via Nepal in the 7th century AD, where it became known as bōcài.^[25] From there, it reached Japan during the Heian period between the 9th and 12th centuries, leading to the development of local varieties adapted to the region's climate.^[30] The plant's introduction to Europe occurred through Arab traders and the Moors, who brought it to Sicily around 827 AD and to the Iberian Peninsula by the 11th century, as documented in agronomic texts like those of Ibn al-ʻAwwām.^[2] Archaeological evidence confirms its cultivation in southern France by the late 12th to mid-13th century, likely via Moorish Spain.^[25] By the 14th century, spinach had reached England, appearing in royal cookbooks such as that of King Richard II, and gained popularity as an early spring vegetable when other greens were scarce.^[2] European colonists introduced spinach to the Americas in the 18th century, with the first commercial seed listings appearing in American catalogs by 1806.^[20] In 16th-century France, Catherine de' Medici, an Italian noblewoman who married King Henry II, elevated spinach's status by insisting it be served at court meals, popularizing creamy preparations now termed "à la Florentine" in homage to her Florentine origins.^[31] During the 19th century, French breeders like Vilmorin-Andrieux advanced cultivation through selections such as the 1829 'Épinard de Flandre' cultivar, which demonstrated improved resistance to bolting under warmer conditions.^[16] Dutch programs from the late 19th century onward built on these efforts, developing late-bolting varieties like 'Nobel' in 1926 to extend growing seasons.^[16]

Cultivation

Growing Conditions

Spinach is a cool-season crop that thrives in moderate temperatures, with optimal daytime growth occurring between 15°C and 20°C (59°F and 68°F).^[32] It tolerates light frost, with young plants able to withstand temperatures as low as -9°C to -7°C (15°F to 20°F) without significant injury.^[4] However, exposure to temperatures above 24°C (75°F), particularly combined with long daylight hours, induces bolting, where the plant prematurely flowers and produces bitter, inedible leaves.^[33] For soil, spinach requires fertile, well-drained loamy soils rich in organic matter to support its shallow root system and high nutrient demands.^[2] The ideal pH range is 6.5 to 7.5, as levels below 6.0 can hinder growth, while it benefits from elevated nitrogen levels to promote vigorous leaf development.^[32] Consistent irrigation is essential, providing 1 to 2 inches of water per week to maintain even soil moisture and prevent bolting from drought stress, with drip systems preferred to avoid wetting foliage.^[33] Planting typically involves direct sowing of seeds 1.3 cm (½ inch) deep in rows spaced 30 cm (12 inches) apart, with initial seed placement 2 to 5 cm (1 to 2 inches) apart within rows.^[4] Thinning is recommended once seedlings reach 5 cm (2 inches) tall, spacing plants 10 to 15 cm (4 to 6 inches) apart to allow for optimal air circulation and leaf expansion.^[2] Succession planting every two weeks ensures a continuous harvest, as spinach completes its vegetative growth cycle in 40 to 50 days under ideal conditions.^[2]

Global Production

Global spinach production reached approximately 34.11 million metric tons in 2023, with China dominating as the largest producer at over 29 million tonnes annually.^[34]^[35] The United States followed as the second-largest producer with approximately 383,000 tonnes in 2023.^[36] In 2024, US production declined to about 280,000 tonnes, a 27% decrease from 2023 due to lower yields.^[37] Other significant contributors included Turkey (approximately 220,000 tonnes), Japan (approximately 82,000 tonnes), and India (approximately 120,000 tonnes) in 2023, each producing hundreds of thousands of tonnes to support both domestic consumption and exports.^[38] This output reflects spinach's status as a high-yield leafy green, cultivated across diverse climates but concentrated in Asia, which accounts for the majority of global supply.^[39] Recent trends in spinach production highlight a growing demand for organic varieties and baby spinach, driven by consumer preferences for healthier, pesticide-free options and convenient ready-to-eat formats.^[40]^[41] Organic production faces challenges like higher input costs and weather-related risks, yet it continues to expand globally.^[42] Additionally, climate change poses threats to yields through altered growing seasons, increased pest pressures, and extreme weather events, prompting adaptations in cultivation practices in vulnerable regions.^[43]^[44] Harvesting methods vary by scale and market segment: large-scale operations often employ mechanical harvesters for efficiency in cutting and collecting mature leaves, while premium and organic spinach is typically hand-picked to minimize damage and ensure quality.^[45]^[46] Post-harvest handling includes hydrocooling, where produce is rapidly chilled with near-freezing water to extend shelf life and preserve freshness during transport and storage.^[47]^[48] These techniques are essential for maintaining the crop's nutritional value and marketability amid rising global demand.^[49]

Nutritional and Health Aspects

Nutritional Composition

Spinach is a low-calorie, nutrient-dense vegetable primarily composed of water, with notable contributions from proteins, carbohydrates, and fiber in its raw form. According to data from the United States Department of Agriculture (USDA), 100 grams of raw spinach contains 23 kilocalories, 91 grams of water, 2.9 grams of protein, 3.6 grams of total carbohydrates (of which 0.4 grams are sugars), and 2.2 grams of dietary fiber. These macronutrients position spinach as a valuable source of plant-based protein and fiber relative to its minimal energy content. The vitamin profile of raw spinach is particularly robust, especially for fat-soluble and B vitamins essential for various physiological functions. Key vitamins include vitamin K at 483 micrograms (402% of the Daily Value, DV), vitamin A (as beta-carotene equivalents) at 469 micrograms (52% DV), and folate at 194 micrograms (49% DV). These levels highlight spinach's role in supporting bone health, vision, and cellular metabolism through its concentrated micronutrient delivery. Raw spinach also provides essential minerals, though bioavailability can vary due to plant compounds. Per 100 grams, it offers 2.7 milligrams of iron (15% DV), 79 milligrams of magnesium (19% DV), and 558 milligrams of potassium (12% DV). Iron and magnesium contribute to oxygen transport and enzymatic reactions, while potassium aids in electrolyte balance. Beyond macronutrients and micronutrients, spinach contains bioactive compounds such as carotenoids and antinutrients. It is rich in lutein and zeaxanthin, totaling approximately 12,198 micrograms per 100 grams, which are macular pigments associated with eye health. Additionally, spinach has a high oxalate content, quantified at around 970 milligrams per 100 grams fresh weight, primarily in soluble form that can influence mineral absorption.^[50]

Health Benefits and Concerns

Spinach consumption provides several health benefits primarily attributed to its rich content of bioactive compounds. The carotenoids in spinach, such as lutein and beta-carotene, exhibit antioxidant properties that help reduce oxidative stress by scavenging free radicals and inhibiting lipid peroxidation in cell membranes.^[51] These effects may contribute to overall cellular protection against damage associated with chronic diseases. Additionally, the high vitamin K content in spinach supports bone health by promoting the carboxylation of osteocalcin, a protein essential for bone mineralization and strength, potentially lowering the risk of fractures in adults.^[52] Folate and dietary fiber found in spinach are linked to potential cancer prevention; folate aids in DNA synthesis and repair, while fiber promotes healthy gut microbiota and reduces inflammation, both of which may lower colorectal cancer risk.^[53] Despite these advantages, spinach also presents certain health concerns due to its chemical composition. The high levels of oxalates in spinach can bind to calcium and iron in the digestive tract, inhibiting their absorption and potentially leading to deficiencies in individuals with low dietary intake of these minerals.^[54] Moreover, excessive oxalate consumption from spinach is a risk factor for kidney stone formation, particularly calcium oxalate stones, in susceptible individuals such as those with a history of nephrolithiasis.^[55] Spinach is also a significant source of nitrates, which, under certain conditions like high intake combined with low vitamin C, can be converted to nitrosamines in the body—compounds associated with increased cancer risk, including gastric and colorectal cancers.^[56] To balance these benefits and risks, health authorities recommend a moderate intake of 1–2 cups of raw or cooked spinach daily for adults as part of a varied vegetable-rich diet, which aligns with general guidelines for 2–3 servings of vegetables per day to support overall health without excessive oxalate or nitrate exposure.^[57] Cooking methods like boiling can reduce oxalate content by up to 80% by leaching soluble oxalates into the water, thereby mitigating absorption issues and kidney stone risks while preserving most nutritional benefits.^[58] Individuals with kidney conditions or absorption disorders should consult healthcare providers for personalized limits.

Culinary Uses

Preparation and Cooking Methods

Spinach requires careful preparation to remove grit and ensure optimal texture. Leaves should be washed thoroughly by separating them and soaking in cool water, or in a solution of 1/2 cup distilled white vinegar per 2 cups of water for five minutes to effectively reduce bacterial contamination, followed by a thorough rinse under running water.^[59] For tender varieties, woody stems are trimmed by folding each leaf lengthwise and pinching off the base, while baby spinach often needs no trimming.^[60] This process not only cleans the leaves but also prepares them for raw or cooked applications. Common cooking methods for spinach emphasize brief exposure to heat to preserve its delicate structure and nutrients. Sautéing typically involves heating a small amount of oil or butter in a pan over medium heat and adding the washed leaves, stirring for 2–3 minutes until wilted and vibrant green.^[61] Steaming, which minimizes nutrient loss compared to boiling, entails placing spinach in a steamer basket over boiling water for about 5 minutes until tender.^[62] Blanching requires submerging the leaves in boiling water for 2 minutes, then immediately transferring to an ice bath; this technique deactivates enzymes, reduces oxalates, and prepares the vegetable for further use.^[63]^[64] Alternatively, spinach can be enjoyed raw in salads, where young, tender leaves contribute a crisp texture without cooking.^[65] For longer storage, spinach is preserved through freezing, canning, or drying after initial blanching. Freezing involves blanching the leaves for 2 minutes, cooling in ice water, draining excess moisture, and packing into airtight freezer bags, where it maintains quality for up to 10–12 months at 0°F.^[66] Pressure canning requires steaming or blanching 1 pound of greens at a time for 3–5 minutes until wilted, packing loosely into hot jars with boiling water, and processing at 11 PSI for dial-gauge canners at 0–2,000 feet altitude (adjust for weighted-gauge canners and higher altitudes per USDA guidelines) for 70 minutes in pints or 90 minutes in quarts.^[67] Drying entails blanching, then spreading the leaves on dehydrator trays at 95–125°F until brittle and crisp (about 8–10 hours), followed by storage in cool, dark airtight containers for up to a year.^[68]

Role in Global Cuisines

In European cuisines, spinach features prominently in savory pastries and egg-based dishes that highlight its earthy flavor and texture. In Greek cooking, spanakopita—a layered pie filled with spinach, feta cheese, and herbs encased in phyllo pastry—serves as a staple appetizer or side, embodying the Mediterranean emphasis on fresh greens and tangy dairy.^[69] Similarly, in Italian traditions, spinach is layered with béchamel sauce, eggs, and nutmeg in baked dishes inspired by Tuscan recipes, creating a creamy, comforting casserole often topped with parmesan.^[70] French-influenced preparations, such as eggs Florentine, pair wilted spinach with poached eggs and hollandaise sauce, transforming the vegetable into a luxurious brunch element that underscores spinach's role in elevating simple proteins.^[71] In British cuisine, post-colonial influences from South Asia have integrated spinach into curries like saag aloo, where it is simmered with potatoes, onions, and spices for a hearty, vegan-friendly main course.^[72] Across Asian cuisines, spinach adapts to diverse cooking techniques that preserve its tenderness while infusing bold seasonings. In Indian dishes, saag paneer combines pureed spinach with cubes of fresh cheese, garlic, ginger, and garam masala, yielding a creamy, spiced curry served with rice or naan to balance richness with heat.^[73] Chinese stir-fries often feature spinach quickly wok-tossed with minced garlic, soy sauce, and sometimes pork fat, resulting in a crisp-tender side that complements rice-based meals and highlights the vegetable's subtle bitterness.^[74] Japanese preparations like ohitashi involve blanching spinach and marinating it in dashi broth, soy sauce, and mirin, creating a chilled side dish that accentuates umami and pairs with steamed rice or grilled fish in minimalist bento-style meals.^[75] In Middle Eastern and Latin American contexts, spinach enriches stuffed pastries and fresh salads, reflecting regional preferences for bold, communal flavors. Middle Eastern fatayer, popular in Lebanese and Palestinian cooking, encases chopped spinach with onions, lemon juice, and sumac in soft dough triangles, baked into handheld pies ideal for mezze platters.^[76] In Mexican cuisine, ensalada de espinacas or espinaca mexicana incorporates spinach into vibrant salads or cooked sides with roasted tomatoes, garlic, onions, and chilies, providing a fresh contrast to richer tacos or stews.^[77] Contemporary global fusions have popularized spinach in health-focused innovations, blending traditional elements with modern convenience. For instance, spinach smoothies merge it with fruits like bananas and berries in blended drinks, drawing from wellness trends to create nutrient-dense beverages that appeal across cultures.^[78]

Cultural Significance

In Popular Culture

Spinach has achieved iconic status in popular culture primarily through its association with the cartoon character Popeye, who debuted in E.C. Segar's comic strip Thimble Theatre on January 17, 1929.^[79] In the strips and subsequent animated adaptations starting in 1933, Popeye consumes canned spinach to gain superhuman strength, often depicted as squeezing open a can and devouring it whole before overpowering adversaries like Bluto.^[80] This portrayal, rooted in a mythologized nutritional benefit linking spinach to enhanced vitality due to its iron content, propelled the vegetable's popularity; U.S. spinach consumption rose by 33% during the 1930s, a surge credited directly to Popeye's influence amid the Great Depression.^[81] The character's appeal extended to merchandise and media, with spinach cans featuring Popeye imagery becoming common, reinforcing the vegetable as a symbol of fortitude in American entertainment.^[82] In literature, spinach appears as part of broader references to greens dating back to the 14th century, notably in Geoffrey Chaucer's The Canterbury Tales, where "wortes"—a term encompassing leafy vegetables like spinach, cabbage, and herbs—are mentioned in contexts of everyday medieval fare and herbal remedies.^[83] This early depiction highlights spinach's integration into historical narratives of sustenance and healing, predating its modern strength-enhancing trope. While not always central, such mentions underscore spinach's enduring presence in literary depictions of food and folklore-inspired tales. Beyond cartoons, spinach features in various media and promotional efforts tied to its Popeye legacy. Animated films and advertisements have occasionally nodded to the vegetable's cultural cachet, with growers' associations leveraging the character for marketing; for instance, in 1937, the Texas Spinach Growers Association erected an eight-foot Popeye statue in Crystal City, Texas—self-proclaimed the "Spinach Capital of the World"—to boost local production and consumption, drawing tourists and solidifying the link between the cartoon and agricultural promotion.^[84] These campaigns, including tie-in products and festivals, have perpetuated spinach's image as a power-boosting food in entertainment, influencing generations through parodies and homages in television and film.^[85]

Symbolic and Folklore Roles

In ancient Persia, where spinach was first domesticated over 2,000 years ago, the plant was venerated for its medicinal virtues and believed to promote vitality and overall health. Known locally as "isfanakh" or "green hand," it was prized as a noble herb that added vigor to dishes and was thought to restore energy. The 9th-century physician Al-Razi described spinach as "temperate, good for the throat, the lungs, the stomach and the liver," emphasizing its role in sweetening the belly and serving as a beneficial food that supported bodily strength and well-being.^[86]^[27] During the Middle Ages in Europe, spinach gained popularity as a medicinal herb associated with health restoration, particularly in Lenten dishes and soups where it was valued for its cooling properties and ability to soothe ailments. Herbalists, including 16th-century writer John Gerard who drew on earlier traditions, regarded it as useful for cleansing the blood, easing stomach issues, and enhancing general vitality, reflecting its integration into folk remedies for purification and endurance. By the 14th century, it had become a common ingredient in monastic and household preparations, symbolizing modest abundance during fasting periods.^[87]^[88] In some Asian cultural traditions, particularly during Lunar New Year celebrations, spinach and other leafy greens symbolize prosperity, growth, and good fortune, representing the abundance of wealth and health for the coming year. These greens are incorporated into festive dishes to invoke blessings of longevity and flourishing, aligning with broader herbal folklore that links verdant plants to renewal and resilience in daily life.^[89] Spinach's symbolic presence extends into modern artistic representations, where it contributes indirectly to themes of vitality through depictions of lush green vegetable fields. For instance, Vincent van Gogh's 1887 painting Vegetable Gardens in Montmartre captures allotment plots filled with greens like spinach, evoking the resilience of rural life amid urban change and highlighting the plant's role in evoking natural abundance.^[90]
