Modern day squash developed from the wild squash that originated in an area between Guatemala and Mexico. Christopher Columbus brought squash back to Europe from the New World, and like other Native American foods, their cultivation was introduced throughout the world by Portuguese and Spanish explorers. Today, the largest commercial producers of squash include China, Japan, Romania, Turkey, Italy, Egypt, and Argentina.

Varieties of winter squash include:
Butternut squash: Shaped like a large pear, this squash has cream-colored skin, deep orange-colored flesh and a sweet flavor.
Acorn squash: With harvest green skin speckled with orange patches and pale yellow-orange flesh, this squash has a unique flavor that is a combination of sweet, nutty and peppery.
Hubbard squash: A larger-sized squash that can be dark green, grey-blue or orange-red in color, the Hubbard's flavor is less sweet than many other varieties.
Turban squash: Green in color and either speckled or striped, this winter squash has an orange-yellow flesh whose taste is reminiscent of hazelnuts.
Pumpkins: The pumpkin with the most flesh and sweetest taste is the small sized one known as sugar or pie pumpkin, the latter referring to its most notable culinary usage.

Varieties of summer squash include:
Zucchini: Probably the best known of the summer squashes, zucchini is a type of narrow squash that resembles a cucumber in size and shape. It has smooth, thin skin that is either green or yellow in color and can be striped or speckled. Its tender flesh is creamy white in color and features numerous seeds. Its edible flowers are often used in French and Italian cooking.
Crookneck and Straightneck Squash: Both of these summer squashes have creamy white flesh and generally have yellow skins, although sometimes you can find them with green skin. Crookneck squash is partially straight with a swan-like neck. It was genetically modified to produce its Straightneck cousin that is shaped as its name implies.
