Cucurbita is a genus of herbaceous fruits in the gourd family, Cucurbitaceae, native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus Lagenaria, which is in the same family and subfamily as Cucurbita, but in a different tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of the Cucurbita species.
Acorn squash, also called pepper squash or Des Moines squash, is a winter squash with distinctive longitudinal ridges on its exterior and sweet, yellow-orange flesh inside. Although considered a winter squash, acorn squash belongs to the same species as all summer squashes.
Cucurbita pepo is a cultivated plant of the genus Cucurbita. It yields varieties of winter squash and pumpkin, but the most widespread varieties belong to the subspecies Cucurbita pepo subsp. pepo, called summer squash.
The zucchini, courgette or baby marrow is a summer squash, a vining herbaceous plant whose fruit are harvested when their immature seeds and epicarp (rind) are still soft and edible. It is closely related, but not identical, to the marrow; its fruit may be called marrow when mature.
A marrow is the mature fruit of certain Cucurbita pepo cultivars used as a vegetable. The immature fruit of the same or similar cultivars is called courgette or zucchini. Like courgettes, marrows are oblong, green squash, but marrows have a firm rind and a neutral flavour, making them useful as edible casings for mincemeat and other stuffings. They can be stored for several weeks after harvest, to be processed for food when required. They are a vegetable used in Great Britain and areas with significant British influence, though their popularity is waning in favor of immature summer squash like courgette.
A pumpkin seed, also known in North America as a pepita, is the edible seed of a pumpkin or certain other cultivars of squash. The seeds are typically flat and asymmetrically oval, have a white outer husk, and are light green in color after the husk is removed. Some pumpkin cultivars are huskless, and are grown only for their edible seed. The seeds are nutrient- and calorie-rich, with an especially high content of fat, protein, dietary fiber, and numerous micronutrients. Pumpkin seed can refer either to the hulled kernel or unhulled whole seed, and most commonly refers to the roasted end product used as a snack.
Cucurbita ficifolia is a species of squash, grown for its edible seeds, fruit, and greens. It has common names including Asian pumpkin, black seed squash, chilacayote, cidra, fig-leaf gourd, and Malabar gourd. Compared to other domesticated species in its genus, investigators have noted that samples of C. ficifolia from throughout its range are relatively similar to one other in morphology and genetic composition. Variations do occur in fruit and seed color, some isozymes, and photoperiod sensitivity.
The Eastern Agricultural Complex in the woodlands of eastern North America was one of about 10 independent centers of plant domestication in the pre-historic world. Incipient agriculture dates back to about 5300 BCE. By about 1800 BCE the Native Americans of the woodlands were cultivating several species of food plants, thus beginning a transition from a hunter-gatherer economy to agriculture. After 200 BCE when maize from Mexico was introduced to the Eastern Woodlands, the Native Americans of the eastern United States and adjacent Canada slowly changed from growing local indigenous plants to a maize-based agricultural economy. The cultivation of local indigenous plants other than squash and sunflower declined and was eventually abandoned. The formerly domesticated plants returned to their wild forms.
Cucurbita moschata is a species originating in either Central America or northern South America. It includes cultivars known as squash or pumpkin. C. moschata cultivars are generally more tolerant of hot, humid weather than cultivars of C. maxima or C. pepo. They also generally display a greater resistance to disease and insects, especially to the squash vine borer. Commercially made pumpkin pie mix is most often made from varieties of C. moschata. The ancestral species of the genus Cucurbita were present in the Americas before the arrival of humans. No species within the genus is fully genetically isolated from all the other species. C. moschata can be hybridized with all other species. It has been suggested that this shows that the species of Cucurbita have diversified more recently than those of related genera such as Cucumis and Citrullus.
Crookneck squash, also known as yellow squash, is a cultivar of Cucurbita pepo, the species that also includes some pumpkins and most other summer squashes. The plants are bushy and do not spread like the plants of winter squash and pumpkin. Most often used as a summer squash, it is characterized by its yellow skin and sweet yellow flesh, as well as its distinctive curved stem-end or "crooked neck". It should not be confused with crookneck cultivars of Cucurbita moschata, such as the winter squash 'Golden Cushaw', or the vining summer squash 'Tromboncino'. Its name distinguishes it from another similar-looking variety of C. pepo, the straightneck squash, which is also usually yellow. There is one similar non-edible C. pepo variety: C. pepo var. ovifera.
Summer squash are squashes that are harvested when immature, while the rind is still tender and edible. Nearly all summer squashes are varieties of Cucurbita pepo, although not all Cucurbita pepo are considered summer squashes. Most summer squash have a bushy growth habit, unlike the rambling vines of many winter squashes. The name "summer squash" refers to the short storage life of these squashes, unlike that of winter squashes.
Delicata squash is a variety of winter squash with cylindrical fruits that are cream-coloured and striped in green or orange. As its name suggests, it has characteristically a delicate rind. It is also known as peanut squash, Bohemian squash, or sweet potato squash. It is a very sweet variety with a thin, edible skin and is typically cut into half rounds and roasted. It is a cultivar of the species Cucurbita pepo, which also includes the summer squash varieties pattypan squash, zucchini, and yellow crookneck squash, as well as winter squash varieties including acorn squash, spaghetti squash, and most pumpkins used as Jack-o-lanterns.
Winter squash is an annual fruit representing several squash species within the genus Cucurbita. Late-growing, less symmetrical, odd-shaped, rough or warty varieties, small to medium in size, but with long-keeping qualities and hard rinds, are usually called winter squash. They differ from summer squash in that they are harvested and eaten in the mature stage when their seeds within have matured fully and their skin has hardened into a tough rind. At this stage, most varieties of this vegetable can be stored for use during the winter. Winter squash is generally cooked before being eaten, and the skin or rind is not usually eaten as it is with summer squash.
Gem squash is a variety of summer squash that may have been domesticated from two wild varieties; Cucurbita texana found in the southern and central United States and Cucurbita fraterna found in Mexico. The dark green spherical fruit, when fully ripe, is about the size of a tennis ball. The young fruit is often harvested before it is fully ripe when it has a more delicate texture flavor.
Cucurbita maxima, one of at least five species of cultivated squash, is one of the most diverse domesticated species. This species originated in South America from the wild subspecies Cucurbita maxima subsp. andreana over 4,000 years ago. Cucurbita maxima, known for modern varieties as Hubbard, Delicious, Marblehead, Boston Marrow, and Turks Turban, originated in northern Argentina near the Andes or in certain Andean valleys. Secondary centers of diversity include India, Bangladesh, Myanmar, and the southern Appalachians.
A pumpkin is a vernacular and typical term for a cultivated orange and round mature winter squash of species and varieties in the genus Cucurbita that has culinary and cultural significance but there is no agreed upon botanical or scientific meaning, and depending on the vernacular, its color and shape may vary. The term pumpkin is sometimes used interchangeably with "squash" or "winter squash", and is commonly used for some cultivars of Cucurbita argyrosperma, Cucurbita ficifolia, Cucurbita maxima, Cucurbita moschata, and Cucurbita pepo.
Cucurbita argyrosperma, also called the cushaw squash and silver-seed gourd, is a species of winter squash originally from the south of Mexico. This annual herbaceous plant is cultivated in the Americas for its nutritional value: its flowers, shoots, and fruits are all harvested, but it is cultivated most of all for its seeds, which are used for sauces. It was formerly known as Cucurbita mixta.
Kamokamo is a variety of Cucurbita pepo, grown as a summer or winter squash in New Zealand. Commonly used in Māori cuisine, the Kamokamo is a heavily ribbed oblate or prolate shaped stocky fruit with speckled green skin, ripening to an orange colour. It is thought to have been introduced to New Zealand during European settlement around the late 19th century and was readily adopted by Māori, displacing the calabash as a food source. Its name originates from the Māori language.
Tromboncino, also known as zucchetta, is a type of squash most often used as a summer squash. While nearly all summer squash are cultivars of Cucurbita pepo, tromboncino is a cultivar of Cucurbita moschata. The vining growth habit is similar to many winter squashes, but unlike most other summer squash. It is more tolerant to some common summer squash pests, including squash vine borer, squash bugs, and powdery mildew, than the more commonly grown, bushy, C. pepo summer squash cultivars. The plants are slower to start producing than some C. pepo types. The fruit color is usually pale green, fading to beige upon maturity, and it is picked around one foot long for summer squash. It is an heirloom, originally from Liguria, and remains popular throughout Italy and abroad. Tromboncino squash can be left to mature into a winter squash; such is often compared to a watery butternut squash. If left to ripen, the fruits can grow over three feet in length. Its flesh is delicious roasted or when prepared in a stew or soup.
Aehobak, also called Korean zucchini or Korean courgette, is an edible, green to yellow-green summer squash. Although nearly all summer squashes are varieties of Cucurbita pepo, aehobak belongs to the species Cucurbita moschata. Commonly used in Korean cuisine, an aehobak has the shape of zucchini, but with thinner, smoother skin, and more delicate flesh. It is usually sold in shrink-wrapped plastic.
