Cucurbita pepo

Cucurbita pepo is an annual herbaceous vine species in the Cucurbitaceae family, characterized by trailing or climbing stems up to 5 meters long, deeply lobed leaves, and large, showy yellow flowers that produce a variety of edible and ornamental fruits, including summer squashes like zucchini and crookneck, winter squashes such as acorn and pumpkin, and decorative gourds.^[1]^[2] Native to Mesoamerica, particularly Mexico, where it was likely first domesticated from wild ancestors around 8,000–10,000 years ago, C. pepo has limited wild populations restricted to specific subspecies in northeastern Mexico and the southern United States, and has been widely cultivated globally for its nutritious fruits, seeds, and flowers.^[1]^[2]^[3] Taxonomically, Cucurbita pepo L. (1753) belongs to the order Cucurbitales within the eudicotyledons, encompassing six recognized varieties such as C. p. var. pepo (field pumpkins) and C. p. var. ovifera (ornamental gourds), reflecting its morphological diversity shaped by human selection.^[4]^[3] The plant thrives in full sun with medium moisture, preferring well-drained soils at temperatures between 17–30°C and annual rainfall of 600–1,500 mm, making it adaptable to temperate and tropical climates but requiring high maintenance due to its sprawling growth and susceptibility to pests.^[1]^[2] Economically and culturally significant, C. pepo provides versatile culinary uses—fruits harvested immature for summer varieties in about 50 days or mature for winter types after 120 days, with edible seeds rich in oil and protein, and flowers suitable for stuffing or soups—while also serving medicinal purposes, such as as an anthelmintic for tapeworms or diuretic in traditional remedies.^[1]^[2]^[3] Its global distribution now spans North America, Europe, and beyond, often escaping cultivation to appear in disturbed habitats, though conservation status is generally secure (G4) due to its cultivated prevalence.^[3]

Botanical Description

Growth Habit and Morphology

Cucurbita pepo is an annual herbaceous plant characterized by a vigorous, trailing or climbing vine growth habit, often adopting a bushy form in cultivated varieties. The stems are five-angled, scabrous, and covered with stiff hairs (setose), featuring branched structures that frequently root at the nodes and bear coiling tendrils for support and climbing. These stems typically sprawl 0.3 to 3 meters in length, though wild forms can extend further, enabling the plant to cover ground or ascend supports efficiently.^[5]^[6]^[7] The leaves are alternate, simple, and palmately lobed with three to five triangular or rhombic-elliptic lobes, forming an ovate to broadly triangular or deltoid blade that is basally cordate and apically acute, with serrated margins. Measuring 20 to 35 cm wide and up to 30 cm long, the leaves are scabrous-hairy on both surfaces, particularly along the veins beneath, providing a rough texture; petioles are grooved, setose, and range from 6 to 24 cm in length. Color varies from solid dark green to yellow-green or with grey-green markings in different cultivars.^[5]^[6]^[1] In cultivation, the overall plant typically attains a height of 30 to 76 cm and a spread of 61 to 91 cm, with domesticated forms often exhibiting reduced prickliness on stems and leaves compared to wild progenitors, alongside proportionally larger vegetative structures for enhanced vigor.^[1]^[6] The root system is fibrous and branched, originating from a well-developed taproot, which remains relatively shallow but supports extensive lateral spread adapted for efficient nutrient and water uptake in loose, well-drained soils.^[5]^[7]

Flowers, Fruits, and Seeds

_Cucurbita pepo is monoecious, bearing both male and female flowers on the same plant.^[8] The flowers are large, bell-shaped, and typically bright yellow to orange in color, measuring 5 to 10 cm in diameter.^[9] Each flower features five petals forming a corolla, with male flowers borne on long, slender peduncles and female flowers distinguished by an inferior ovary beneath the petals.^[10] These reproductive structures emerge from the leaf axils, with male flowers often outnumbering females to facilitate pollination.^[8] The fruits of Cucurbita pepo are botanically classified as pepos, a type of berry characterized by a fleshy interior enclosed in a hard or leathery rind derived from the ovary wall.^[9] Fruit morphology varies widely among cultivars, ranging from small, elongated forms like zucchini, which measure 10 to 20 cm in length, to massive spherical pumpkins that can weigh up to 50 kg or more in select varieties.^[11]^[12] Colors span green, yellow, orange, and even variegated patterns, influenced by genetic factors and maturation stage.^[9] Winter varieties develop a tough, durable rind for long-term storage, while summer types retain a tender, edible skin when harvested young.^[13] Seeds within the fruits are flat and oval-shaped, typically 1 to 2 cm in length, with a smooth, papery coat that is white to cream-colored in wild forms.^[5] Cultivated varieties often produce larger seeds, and some hull-less (thin-skinned) types are bred for easier processing and higher oil content.^[14] In certain parthenocarpic cultivars, particularly among summer squashes, fruits develop without fertilization, resulting in seedless or nearly seedless produce that enhances market appeal.^[15] Fruit maturation in Cucurbita pepo differs markedly between summer and winter types. Summer squashes, such as zucchini, are harvested immature while the rind is soft and the flesh tender, typically within 40 to 60 days of planting.^[16] In contrast, winter squashes and pumpkins are allowed to fully mature on the vine, developing a hard rind over 80 to 120 days, which protects the seeds and flesh for extended storage of several months.^[13] This distinction arises from selective breeding within subspecies, where morphological variations influence harvest timing and post-harvest longevity.^[17]

Taxonomy and Evolution

Etymology and Domestication History

The genus name Cucurbita derives from the Latin word for "gourd," referring to the bottle gourd (Lagenaria siceraria), while the specific epithet pepo originates from the Greek pepōn, meaning "ripe" or "large melon," alluding to the mature, fleshy fruit.^[5]^[18] Cucurbita pepo was first formally described by Carl Linnaeus in his Species Plantarum in 1753, establishing it as a key species within the Cucurbitaceae family.^[19] Domestication of C. pepo began approximately 8,000 to 10,000 years ago in Mesoamerica, with evidence pointing to southern Mexico as the primary center of origin.^[20] Archaeological remains from Guilá Naquitz cave in Oaxaca, Mexico, dated to around 10,000 years before present (BP), represent the earliest known domesticated C. pepo specimens, characterized by larger rinds indicative of human selection for non-bitter fruits.^[21] This subspecies, C. pepo subsp. pepo, emerged from wild ancestors through intentional cultivation by indigenous peoples. Independently, a second domestication event occurred in eastern North America, giving rise to C. pepo subsp. ovifera, supported by molecular and archaeobotanical data showing distinct lineages.^[22]^[23] Prior to European contact, indigenous groups across the Americas cultivated C. pepo for food, containers, and tools, spreading it from Mesoamerica northward and southward over millennia.^[24] In eastern North America, evidence from the Cloudsplitter rockshelter in Kentucky, dated to about 4,000 BP, includes rind fragments of domesticated C. pepo subsp. ovifera, highlighting local adaptation alongside other native crops like sunflower and marshelder.^[25] These pre-Columbian practices underscore C. pepo's role in early agricultural systems, with selections favoring diverse fruit shapes and sizes for versatile uses. Following Christopher Columbus's voyages in 1492, C. pepo was introduced to Europe, with the earliest documented images appearing in French and Italian records between 1503 and 1508.^[26] By the mid-16th century, the species had integrated into European horticulture and cuisine, particularly in Italy, where young fruits were consumed as a novel vegetable, spurring further diversification.^[27] Transoceanic exchanges by explorers facilitated its rapid global spread, establishing C. pepo as a staple in temperate and subtropical regions worldwide by the end of the 16th century.^[28]

Classification and Subspecies

Cucurbita pepo is classified within the family Cucurbitaceae, which comprises about 800 species of vines and herbs, and the genus Cucurbita, encompassing approximately 13 species of annual or perennial plants native primarily to the Americas.^[29] The species C. pepo itself includes domesticated and wild forms, with historical synonyms such as Cucurbita melopepo L. applied to certain cultivated lineages and C. ovifera L. to gourd-like variants.^[30] Within the infrageneric taxonomy, C. pepo forms part of the C. pepo complex, a group of closely related taxa distinguished by molecular markers; post-2012 studies using whole-genome resequencing and SNP data have confirmed the monophyly of this complex through shared genetic variants associated with fruit morphology and domestication traits.^[31] Three subspecies are widely recognized based on morphological, allozyme, and DNA evidence: C. pepo subsp. pepo (cultivated squashes and pumpkins), subsp. ovifera (ornamental gourds and associated wild forms), and subsp. fraterna (a rare wild taxon from northeastern Mexico).^[30] These differ primarily in fruit size and shape—cultivated forms in subsp. pepo and subsp. ovifera exhibit enlarged, fleshy fruits compared to the small, bitter ones in subsp. fraterna—as well as seed morphology, with domesticated seeds being larger and lacking marginal wings, and habitat adaptations, where wild subspecies favor arid, disturbed sites while cultivated ones are adapted to agricultural settings.^[29] Subsp. ovifera further includes wild varieties such as var. texana (restricted to riverine habitats in Texas and Oklahoma) and var. ozarkana (found in eastern U.S. woodlands, occasionally referred to under older names like michauxii), which show intermediate seed and fruit traits bridging wild and domesticated populations.^[30] Domestication from wild progenitors like subsp. fraterna and subsp. ovifera var. texana has led to the diversification within subsp. pepo and subsp. ovifera.^[31] The cultivated forms are organized into eight major cultivar groups based on fruit morphology, with four under each cultivated subspecies: under subsp. pepo, the Pumpkin Group features large, round fruits for storage; the Zucchini Group includes elongated, tender summer squashes; the Cocozelle Group has slender, tapered fruits; and the Vegetable Marrow Group produces bulbous, marrow-like squashes. Under subsp. ovifera, the Acorn Group comprises ridged, acorn-shaped winter squashes; the Crookneck Group offers curved-neck summer squashes; the Straightneck Group has uniform cylindrical fruits; and the Scallop Group (Pattypan) displays saucer-shaped, scalloped summer squashes.^[31] Ornamental gourds, primarily from subsp. ovifera, form additional groups valued for decorative, non-edible fruits with diverse colors and shapes, such as the small, hard-shelled varieties used in crafts.^[29]

Distribution and Habitat

Native Range and Wild Populations

Cucurbita pepo is native to central and eastern North America, with its wild range extending from northeastern Mexico through the southern United States to southern Canada, including regions such as Ontario and Quebec. Wild populations primarily occupy disturbed habitats, including riverbanks, floodplains, sand and gravel bars, agricultural fields, and woodland edges, often in open, sunny areas with well-drained soils. These plants thrive from sea level up to elevations of approximately 2,000 meters, favoring subtropical and temperate zones where they grow as annuals.^[29]^[3]^[32] Key wild subspecies exhibit distinct habitat preferences within this range. C. pepo subsp. fraterna, considered the closest wild progenitor, is restricted to arid highlands and seasonally dry thornscrub in northeastern Mexico, such as upland areas around Tamaulipas and San Luis Potosí. Subsp. texana (often classified under subsp. ovifera) occurs in grasslands and open disturbed sites across Texas, Oklahoma, and adjacent areas, including stream valleys and prairies. In eastern woodlands, populations associated with subsp. ovifera var. ozarkana are found in floodplain forests and riverine habitats from the Ozark Mountains through Illinois, Missouri, and Arkansas, though some classifications reference var. michauxii for similar eastern forms.^[33]^[34]^[32]^[29] Wild C. pepo populations often behave as weedy annuals, with some acting as escapees from early cultivation sites, leading to naturalized stands in human-modified landscapes. However, they face significant threats from habitat loss due to agricultural expansion, urbanization, and river channelization, as well as genetic swamping through hybridization with cultivated varieties, which can increase weediness and reduce pure wild genetic diversity. Climate change projections suggest potential range contractions, with up to 80% loss of suitable habitat for subsp. fraterna by 2060. These dynamics highlight the vulnerability of wild C. pepo, from which domesticated forms originated around 10,000 years ago in Mexico.^[35]^[36]^[33]

Introduced and Cultivated Ranges

_Cucurbita pepo was introduced to Europe in the early 16th century following the Columbian Exchange, with the first documented images appearing around 1503–1508 and cultivars recorded by 1542.^[37]^[38] Its spread to Asia, Africa, and other regions accelerated in the 19th century, establishing it as a global crop.^[39]^[39] Today, it is cultivated in over 100 countries across temperate, subtropical, and tropical zones.^[28]^[28] Major producing countries include China, India, and the United States, where production focuses on diverse varieties for fresh consumption and processing.^[40]^[40] In the USA, Illinois leads as the top state, harvesting approximately 690 million pounds in 2023, primarily for canned pumpkin products.^[41]^[41] Global production reached about 23 million tonnes in 2022, reflecting its adaptation to varied climates through selective breeding of cultivars suited to local conditions.^[42]^[42] While primarily cultivated, C. pepo occasionally escapes cultivation to form feral populations in warm climates, such as the Mediterranean basin and parts of Australia, where it can behave as an environmental weed or agricultural escapee.^[43]^[43] However, it is generally not considered highly invasive, with limited ecological impact compared to other introduced species.^[44]^[44]

Ecology

Pollination and Interactions

Cucurbita pepo, like other cucurbits, relies heavily on insect pollination for successful reproduction, with flowers typically opening early in the morning and closing by midday to coincide with peak pollinator activity.^[10] The primary pollinators are specialist squash bees from the genera Peponapis and Xenoglossa, which have co-evolved with Cucurbita species and exhibit high efficiency in pollen transfer due to their adaptation to the large, bowl-shaped flowers.^[45] In wild populations, many forms of C. pepo display self-incompatibility, promoting outcrossing and genetic diversity through obligatory cross-pollination by these bees.^[46] In commercial cultivation, where natural pollinator density may be insufficient, hand-pollination is often employed to ensure fruit set, particularly in enclosed or high-density settings.^[8] Beyond pollination, C. pepo engages in symbiotic interactions that support beneficial insects, primarily through its flowers providing abundant pollen and nectar resources that sustain squash bee populations nesting in nearby ground.^[47] Nitrogen-fixing associations are rare in C. pepo, as it lacks the nodulating symbioses typical of legumes, though some plant growth-promoting rhizobacteria may indirectly enhance nitrogen availability in the soil.^[48] The plant also exhibits allelopathic effects on neighboring vegetation via root exudates, which can inhibit weed germination and growth, such as reducing shoot and root biomass in species like Amaranthus retroflexus.^[49] In wild settings, C. pepo fruits play a key role in plant-animal interactions by attracting mammals for seed dispersal; historical evidence from megafauna dung indicates that large herbivores consumed the fruits and distributed viable seeds over long distances, a mutualism disrupted by Pleistocene extinctions.^[50] While birds may occasionally contribute to dispersal through fruit pecking, mammals were the dominant vectors in ancestral ecosystems. In contrast, cultivated varieties depend on human-managed pollination rather than natural dispersal, limiting their role in wildlife interactions.^[50] Recent studies from 2020 to 2025 highlight the vulnerability of C. pepo yields to declining pollinator populations, with squash bee nest initiations reduced by up to 85% in pesticide-exposed areas, leading to unharvested pollen and lower fruit production.^[51] These declines exacerbate pollination deficits in agroecosystems, where C. pepo fields can nonetheless bolster biodiversity by serving as habitats for native bees and associated microbiota, enhancing overall ecological resilience.^[52]^[53]

Pests, Diseases, and Environmental Impact

Cucurbita pepo faces significant threats from several major insect pests that target its stems, leaves, and fruits. The squash vine borer (Melittia cucurbitae) is a primary concern, with its larvae tunneling into the base of stems, causing wilting, girdling, and often plant death by disrupting vascular tissue.^[54] Squash bugs (Anasa tristis) feed by sucking sap from leaves and stems, leading to yellowing, wilting, and transmission of diseases like cucurbit yellow vine decline, while also causing fruit blemishes through direct feeding.^[54] Cucumber beetles, including the striped (Acalymma vittatum) and spotted (Diabrotica undecimpunctata howardi) species, chew on foliage, flowers, and developing fruits, resulting in defoliation, scarring, and transmission of bacterial wilt (Erwinia tracheiphila).^[54] Diseases also pose substantial risks to C. pepo, with fungal and viral pathogens causing widespread damage. Powdery mildew, caused by Podosphaera xanthii (formerly Sphaerotheca fuliginea), manifests as white powdery colonies on leaf upper surfaces, leading to yellowing, premature defoliation, and reduced photosynthesis that stunts fruit development.^[55] Downy mildew (Pseudoperonospora cubensis) produces angular yellow lesions on leaves that turn brown, with grayish-purple sporulation on undersides, ultimately causing leaf blight and yield losses up to 100% in severe cases.^[54] Viral infections, such as zucchini yellow mosaic virus (ZYMV), result in mottled, distorted leaves and fruits with irregular, warty surfaces, severely reducing plant vigor and marketability; transmission occurs via aphids, and management relies on resistant varieties where available.^[55]^[54] The cultivation of C. pepo has notable environmental impacts, particularly on soil health and biodiversity. Crop rotations with non-cucurbit species over 3–5 years are essential to prevent soil nutrient depletion, reduce pathogen buildup, and maintain microbial diversity, as continuous planting exacerbates issues like nitrogen leaching and erosion.^[56]^[57] Pesticide applications, including neonicotinoids like thiamethoxam and imidacloprid commonly used against cucumber beetles, contaminate pollen and nectar, posing risks to pollinators such as squash bees (Peponapis pruinosa) through direct toxicity and sublethal effects like impaired foraging.^[58]^[59] Wild populations of C. pepo contribute to habitat biodiversity and can support restoration efforts by providing genetic resources for disease resistance, but gene flow from cultivated hybrids threatens their genetic purity through introgression, potentially leading to reduced fitness in wild relatives.^[60]^[61] Regarding climate adaptation, C. pepo exhibits vulnerability to abiotic stresses, being highly sensitive to frost—which damages tender tissues at temperatures below 0°C—and drought, which reduces yield by limiting water availability during fruit set.^[62] Recent research from 2020–2025 has focused on identifying drought-tolerant genotypes among pumpkin lines, evaluating traits like relative water content and yield stability under stress, to enhance resilience amid warming temperatures and erratic precipitation patterns.^[63]^[64]

Cultivation

Growing Requirements and Practices

Cucurbita pepo thrives in well-drained, fertile loamy or sandy loam soils with a pH range of 6.0 to 6.8, which supports optimal nutrient uptake and root development.^[65]^[66] As a warm-season crop, it requires full sun exposure for at least 6–8 hours daily and temperatures between 20°C and 30°C for vigorous growth, with a minimum soil temperature of 15.5°C (60°F) at planting to ensure germination.^[67]^[68] The plant demands 100–150 frost-free days to reach maturity, making it sensitive to frost, which can damage seedlings and vines.^[69] Planting can occur via direct sowing after the last frost or through transplants, though the latter requires careful handling to avoid root disturbance in vining types.^[70] Seeds should be sown 2–5 cm deep in hills or rows spaced 1.2–1.8 m apart, with plants 0.6–1.2 m within rows to accommodate sprawling vines.^[71] For vining varieties, trellising supports vertical growth, reducing disease risk and optimizing space in smaller fields.^[72] Consistent moisture is essential, with irrigation providing 25–50 mm of water per week, preferably through drip systems to target roots and minimize foliage wetting.^[65]^[73] Harvesting timing differs by type: summer squashes are picked immature at 15–20 cm in length, typically 50–60 days after planting, to maintain tenderness.^[71] Winter squashes and pumpkins are harvested at full maturity, when rinds harden and resist fingernail puncture, around 85–120 days post-planting.^[74] Yields vary by management and variety but average 20–40 tons per hectare for commercial production under irrigation.^[56]^[16] Recent advancements from 2020 to 2025 emphasize sustainable practices, including conservation tillage to reduce erosion and improve soil health in vegetable fields.^[75] Drip irrigation has become standard for water conservation, delivering precise amounts while integrating with mulches to warm soils and suppress weeds.^[76] Organic methods rely on compost amendments and cover crops to build soil health, improving resilience without synthetic inputs.^[66] In response to climate change, growers adapt by shifting to earlier planting dates, leveraging warmer springs to extend the season and mitigate heat stress later.^[77] Requirements may vary slightly by variety.

Breeding and Genetic Diversity

Cucurbita pepo exhibits significant genetic diversity, particularly in its wild relatives such as subspecies ovifera and texana, which harbor moderate to high levels of variation that have been crucial for breeding programs.^[78] Genetic studies using markers like simple sequence repeats (SSRs) have revealed distinct clusters within subsp. texana, reflecting adaptations to diverse environments, while subsp. ovifera shows clear differences in genetic variation and linkage disequilibrium compared to the domesticated subsp. pepo.^[30] Gene flow between wild and cultivated populations is well-documented, especially in Mexican landraces, where historical and recent exchanges have influenced diversity and adaptation.^[78] Core collections, such as the USDA's germplasm repository in Ames, Iowa, maintain over 829 accessions of C. pepo, serving as vital resources for preserving this diversity against erosion from modern monocultures.^[79] Breeding efforts in C. pepo primarily target disease resistance, improved fruit quality, and higher yields, with hybrid varieties becoming dominant in commercial production since the 1980s due to their heterosis effects on uniformity and vigor.^[80] Introgression of resistance genes from related species like C. moschata has produced hybrids with enhanced tolerance to viruses and other pathogens, while selection for traits like soluble solids content and fruit size has improved market value.^[81] These goals address challenges in summer and winter squash types, prioritizing pest-resistant lines that reduce chemical inputs and boost productivity in diverse agroecosystems.^[82] Recent genomic research from 2020 to 2025 has advanced C. pepo improvement through whole-genome sequencing and molecular tools. A 2025 study sequenced eight varieties at 22–40X coverage, identifying variations in genes linked to agronomic traits like yield and quality, facilitating marker-assisted selection.^[83] A September 2025 QTL analysis developed recombinant inbred lines and identified loci for plant architecture traits such as vine length and fruit shape, aiding molecular breeding for compact varieties suited to modern farming.^[84] SSR markers have been developed and applied to assess diversity in ornamental gourds and landraces, enabling precise genotyping for breeding.^[85] Evolutionary genomics analyses confirm Mexico as the center of origin, with population studies of landraces revealing structure, bottlenecks, and adaptation signals that inform conservation and breeding strategies. Although CRISPR applications in Cucurbitaceae focus on related species for traits like parthenocarpy, ongoing genome editing efforts hold promise for C. pepo fruit development under stress.^[86] Conservation strategies for C. pepo emphasize both in situ protection of wild populations in their native ranges in the United States and ex situ maintenance in global germplasm banks to safeguard against genetic erosion from intensive cultivation.^[35] In situ efforts prioritize habitat preservation for subspecies like ovifera and texana, which serve as genetic sources for cultivated varieties, while ex situ collections, including those from the USDA and European genebanks, ensure long-term viability through replenishment and characterization.^[87] These complementary approaches counter the vulnerabilities posed by monoculture expansion, supporting sustainable breeding by maintaining diverse accessions for future trait introgression.^[88]

Uses

Culinary and Nutritional Applications

_Cucurbita pepo encompasses a range of squashes and pumpkins with diverse culinary applications, particularly in fresh and cooked preparations. Summer squash varieties, such as zucchini (C. pepo var. cylindrica), are commonly eaten raw in salads for their mild flavor and crisp texture or lightly stir-fried to retain tenderness in vegetable medleys.^[89] Winter squash types, including pumpkins (C. pepo subsp. pepo), are typically baked whole or in pieces to develop sweetness, or pureed into smooth consistencies for soups, pies, and custards, leveraging their dense flesh and natural sugars.^[89] The seeds, often roasted to enhance nutty flavors, serve as snacks or ingredients in dishes like Mexican pepitas, providing a crunchy element rich in oils.^[90] Edible flowers from C. pepo plants are harvested young and used stuffed with cheese or herbs before frying, or incorporated into soups and stir-fries for a delicate, slightly sweet taste.^[91] Nutritionally, the fruits of C. pepo are low in calories, generally 17–40 kcal per 100 g depending on the variety and preparation, making them suitable for weight-conscious diets while offering high levels of vitamin A precursors like beta-carotene, vitamin C, and dietary fiber that support immune function and digestion.^[92] Pumpkin flesh, in particular, stands out for its carotenoid content, which contributes to its orange hue and antioxidant properties.^[93] The seeds provide a denser nutritional profile, containing approximately 30% protein with all nine essential amino acids, alongside unsaturated fats, magnesium, and zinc that aid in muscle health and metabolism.^[94] Phytochemicals such as phenolic compounds and cucurbitacins in various parts further enhance the antioxidant capacity, helping to combat oxidative stress.^[95] Processing methods extend the shelf life and usability of C. pepo, with canning and freezing preserving the nutritional integrity of fruits for year-round consumption; pumpkin puree, derived primarily from processing mature fruits, dominates the global market as a versatile base for baked goods and beverages.^[96] In 2023, U.S. pumpkin production reached about 1.6 billion pounds, underscoring its role as a market leader in puree output, though global production is headed by China.^[97] Recent breeding programs have targeted nutritional improvements, such as elevating carotenoid levels through genome-wide association studies to boost vitamin A equivalents in edible varieties.^[98] As a naturally gluten-free and vegan ingredient, C. pepo features prominently in diverse diets, including traditional Native American succotash—a stew blending squash with corn and beans to symbolize the "Three Sisters" planting method and provide balanced plant-based nutrition.^[99]

Medicinal Uses

The seeds of Cucurbita pepo have been traditionally employed as an anthelmintic agent to expel intestinal parasites, owing to their content of cucurbitacin compounds that exhibit antiparasitic activity.^[100] Additionally, the seeds possess diuretic properties, aiding in the treatment of urinary disorders and edema by promoting urine production.^[101] Pumpkin seed oil derived from C. pepo is widely used for managing benign prostatic hyperplasia, where it inhibits prostate enlargement and improves urinary flow through its phytosterol content, as demonstrated in clinical trials comparing it to standard treatments like tamsulosin.^[102] The plant also contains anti-inflammatory compounds, such as flavonoids and phenolic acids in the seeds, which contribute to reducing inflammation in conditions like arthritis and skin irritations.^[101] Recent studies from 2025 highlight the cardiovascular benefits of pumpkin seed extract, showing its ability to lower blood pressure, improve lipid profiles, and enhance nitric oxide production for vascular protection due to high magnesium and antioxidant levels.^[103]

Cultural Uses

Among the Zuni people of the American Southwest, gourds from Cucurbita pepo are crafted into ceremonial rattles used in anthropic and zoomorphic worship rituals, symbolizing connection to spiritual realms, while the plants also provide dyes for traditional textiles and body paints.^[104] In broader Indigenous American cultures, C. pepo holds significance in harvest rituals and festivals, where pumpkins represent abundance and are incorporated into prayers for bountiful yields, as seen in Apache ceremonies and other tribal autumn celebrations.^[105] In contemporary Western traditions, C. pepo pumpkins serve as powerful symbols during Halloween, carved into jack-o'-lanterns to ward off evil spirits, a practice rooted in Celtic Samhain festivals adapted after European contact with Native American crops.^[106]

Ornamental Uses

Ornamental varieties of Cucurbita pepo, particularly the hard-shelled gourds (C. pepo var. ovifera), are prized for crafts and decorations due to their diverse shapes, colors, and textures, often dried and used in autumn displays, wreaths, and artistic sculptures.^[107] Miniature pumpkin cultivars, such as those in the Jack Be Little series, are popular in home gardens for their compact size and vibrant hues, adding aesthetic value to ornamental landscapes without requiring extensive space.^[108]

Other Uses

Pumpkin residues from Cucurbita pepo, including vines and unmarketable fruits, serve as nutritious animal fodder, providing fiber, vitamins, and energy to livestock like cattle and pigs, thereby reducing waste in agricultural systems.^[109] The seeds offer biofuel potential, with their high oil content (up to 50%) suitable for biodiesel production, as explored in Greek studies converting pumpkin seed oil into renewable fuel feedstocks.^[110] Environmentally, C. pepo vines function as living mulches or cover crops in rotations, suppressing weeds, enhancing soil moisture retention, and improving fertility through organic matter addition in sustainable farming practices.^[111]
