Winter squash plants are annual vining plants that produce edible fruits in the fall. They have large, lobed leaves, and their vines can grow up to 15 feet long. Winter squash plants produce yellow flowers that eventually develop into the squash fruits. The fruits are typically hard-skinned and range in size from small to very large. They can have smooth or warty skin and come in a variety of colors, including yellow, green, orange, and red. Winter squash is a popular vegetable for roasting, baking, and pureeing into soups and sauces.
