Even though some varieties grow on vines while others grow on bushes, squash are commonly divided into the two groups, summer and winter. There are several types of summer squash, but zucchini is the most popular summer squash purchased in the United States. Summer squash come in many different colors and shapes. The different varieties of squash can be used interchangeable in most recipes, because most squash are similar in texture and flavor.

Place summer squash in plastic bags and store in the refrigerator. Fresh summer squash should keep for up to a week. Thicker-shinned varieties such as chayote will stay fresh for two weeks or longer.
