David Livingstone, the African explorer, described watermelon as abundant in the Kalahari Desert and the species descriptor, vulgaris, means "common" (Shosteck, 1974). This flowering plant bears an accessory fruit of a type that botanists call a false berry. The watermelon fruit, loosely considered a type of melon (although not in the Genus Cucumis), has a smooth exterior rind and a moist, sweet, usually red interior flesh.

Agricultural aspects

Watermelon

Until the 1940s, the watermelon was rarely found in a grocery. Melon lovers had to grow their own, which tended not to keep for long. Then a USDA plant breeder set out to produce a better watermelon. The result was "that gray melon from Charleston," formally called the Charleston Gray. Its oblong shape and hard rind made it easy to stack and ship. Its adaptability meant it could be grown over a wide geographical area. It produced high yields and was resistant to the most serious watermelon diseases: anthracnose and fusarium wilt. Best of all, it tasted terrific. Today, almost all commercial watermelon varieties have some Charleston Gray in their lineage.

This now common watermelon is large enough that groceries often sell half or quarter melons. There are also some smaller, spherical varieties of watermelon, both red- and yellow-fleshed. So-called "seedless" watermelons have far fewer, and softer, seeds than average, but generally contain at least a few pale seeds.

Compared with most fruits, the watermelon has a very high water content, and can be used to satisfy thirst. Watermelons seeds are roasted by Asians. Pickling watermelons is widespread in Russia, and pickled watermelon rind is also popular in the West.

For commercial plantings, one bee hive per acre (4,000 m² per hive) is the minimum recommendation by the US Department of Agriculture for pollination of conventional seeded varieties. Seedless hybrids have sterile pollen and pollinizer rows of varieties with viable pollen must also be planted, and the pollinator density increased to three hives per acre (1,300 m² per hive).

Watermelon connotations

The watermelon slice is striking and unmistakable in appearance. In former times, African Americans were depicted in racist caricatures as being inordinately fond of watermelon. The image of the watermelon, allusions to eating watermelon, and so forth, may still be seen as offensive. The historical perspective is that watermelons are native to Africa, and their seeds and culture were brought to the US, and taught by Africans.
