Squash

Squash refers to the edible fruits of several plants in the Cucurbita genus, which belongs to the Cucurbitaceae family. This group includes many familiar varieties, such as zucchini, butternut squash, acorn squash and other winter squashes. Botanically, these are fruits because they develop from flowers and contain seeds, although they are commonly prepared as vegetables. Squash plants are annual vines with large leaves and separate male and female flowers.

Depending on the species and variety, the stems may spread along the ground or climb with support. The fruits vary greatly in shape, size, color and texture. Some are harvested while still young and tender, whereas others are allowed to mature fully, developing a harder skin that helps protect them during storage. Most squash grows best in warm weather, with plenty of sunlight and fertile, well-drained soil. Squash can be prepared in many ways.

Young varieties such as zucchini are often eaten sautéed, grilled, baked or added to soups, while mature winter squashes are commonly roasted, steamed, mashed or used in stews and pies. Their flesh contains a high proportion of water and can provide dietary fiber, potassium, vitamin C and carotenoids. Orange-fleshed varieties are often rich in beta-carotene, a pigment that the body can convert into vitamin A.

The seeds of many squash varieties are also edible and can be cleaned, dried and roasted. Squash flowers can be eaten as well in some culinary traditions. Mature winter squashes may keep for several months when stored in a cool, dry and well-ventilated place, although storage life varies with the variety and condition of the fruit. Because squash plants produce large leaves and spreading stems, they generally need more space than compact vegetables.
