Melon: types, botany, cultivation and culinary uses

Botany and classification

Most melons belong to the family Cucurbitaceae. Within that family many fall in the genus Cucumis, which contains the muskmelon group, while other familiar types belong to different genera. The muskmelon and its close relatives are often discussed under the common name muskmelon. The well-known red-fleshed watermelon is classified in the genus Citrullus. Descriptions that emphasize fruit form and development sometimes use the term botanically to explain that melons are pepos — a type of berry with a hard rind. In culinary settings, several are treated like vegetables (for example, bitter melon) despite their botanical category.

Main types and characteristics

• Muskmelons: aromatic flesh, often netted rind, includes cantaloupe varieties.
• Honeydew and related sweet-fleshed melons with smooth rind and pale flesh.
• Watermelon (Citrullus): large, watery fruit usually with red or yellow flesh and many seeds.
• Bitter melon and wax gourd (Benincasa): used as vegetables in some cuisines.

Common features include trailing vines, tendrils, large lobed leaves and flowers that lead to single large fruits. Size, flesh firmness, sweetness and seediness vary by type and cultivar.

History, cultivation and uses

Melons have ancient origins and were cultivated in several regions including Africa, Asia and the Mediterranean. The English word 'melon' derives from the Latin melopepo, itself borrowed from Greek μηλοπέπων (mēlopepon). Today they are grown worldwide in temperate and tropical climates. Cultural practices include warm-season planting, trellising for smaller-fruited types, and irrigation to produce sweet, juicy flesh.

Uses are diverse: eaten fresh, in salads, desserts and beverages; preserved by drying or pickling; or cooked in savory preparations. Nutritionally, many melons are high in water and provide modest amounts of vitamins (notably vitamin C) and minerals.

Storage, selection and notable facts

Select ripe melons by aroma, slight softness at the stem end or a uniform ground spot depending on type. Store whole melons at cool room temperature until ripe and refrigerate cut fruit. Melons are important in agriculture and cuisine for their seasonal sweetness and hydrating qualities.
