Cucumber
The cucumber plant Cucumis sativus belongs to the family Cucurbitaceae, a group of creeping vines that root in soil and climb trellises using thin spiraling tendrils. Native ranges extend from India through Nepal, Bangladesh, China's Yunnan province, and Northern Thailand. Botanists classify its fruit as a pepo, a type of berry with seeds encased in an outer rind. This botanical definition contrasts sharply with culinary usage where it is treated as a vegetable. Three main cultivar groups exist today: slicing varieties eaten fresh, pickling types bred for brine, and seedless parthenocarpic strains grown without pollination.
Cultivated cucumbers were domesticated in India at least 3,000 years ago from wild C. sativus var. hardwickii populations. East Asian cultivars diverged from Indian stock approximately 2,500 years ago according to demographic modeling. Records show cultivation appearing in France during the 9th century and England by the 14th century. North American adoption occurred by the mid-16th century when Spanish explorers brought seeds to Haiti in 1494. Jacques Cartier found large cucumbers growing near Montreal in 1535 after French expeditions arrived. The Mandan and Abenaki tribes on the Great Plains obtained these crops from Spanish traders and integrated them into existing agricultural systems alongside corn beans pumpkins and squash.
Emperor Tiberius maintained daily cucumber supplies year-round using artificial growing methods described by Pliny the Elder. Roman growers utilized mirrorstone or lapis specularis believed to be sheet mica to create early greenhouse conditions. Specularia houses glazed with oiled cloth allowed cultivation through winter months. Charlemagne ordered cucumbers grown in his gardens during the 8th and 9th centuries. Christopher Columbus introduced the crop to Europe via Spain before transporting it to the Caribbean. By the 17th century Reverend Francis Higginson documented abundant cowcumbers growing in Boston Harbor's Governor's Garden. William Wood published observations of New England agriculture in 1633 noting local farmers cultivated these vegetables extensively.
A strong prejudice developed against uncooked vegetables during the later 17th century claiming they caused summer diseases. Contemporary health publications stated such plants should be forbidden to children entirely. Cucumber gained a reputation as fit only for consumption by cows leading to the name cowcumber. Samuel Pepys recorded in his diary on the 22nd of August 1663 that Mr. Newburne died from eating cowcumbers. John Evelyn wrote in 1699 that cucumbers were thought little better than poison regardless of preparation method. Eighteenth-century British physician Samuel Johnson claimed English doctors advised slicing them well then throwing them away as good for nothing. A copper etching by Maddalena Bouchard between 1772 and 1793 depicted smaller almost bean-shaped fruits with small yellow flowers.
An international team of researchers announced sequencing the cucumber genome in 2009. Studies of genetic recombination during meiosis provided high resolution landscapes of DNA double strand breaks and crossovers. Parthenocarpic cultivars produce seedless fruit without pollination though this degrades eating quality for some consumers. These varieties are usually grown in greenhouses where bees are excluded or outdoors in regions excluding bee access. Traditional cultivars produce male blossoms first then female in about equivalent numbers while newer gynoecious hybrids generate almost all female flowers. Temperature changes can induce male flowers even on these plants providing sufficient pollen for pollination to occur naturally.
World production of cucumbers and gherkins reached 98 million tonnes in 2023 according to global statistics. China dominates output accounting for 82% of total worldwide harvest. Slicing cucumbers sold commercially in North America tend longer smoother more uniform in color with tougher skin than European varieties. European cucumbers often called telegraph cucumbers in Australasia grow smaller with thinner delicate skin frequently wrapped in plastic. Picklers measure approximately 15 centimeters long and 4 centimeters wide featuring bumpy skin dotted with tiny white or black spines. Gherkins typically measure 5 centimeters in length and serve as baby pickles used primarily for brining processes.
