Summer squash is native to North America, where it was commonly cultivated by Native Americans. Squash was planted as a companion to corn and beans in a trio known as the “three sisters.” Each plant in the trio benefited each other: the corn provided support for climbing beans, while the beans fixed nitrogen in the soil, and the large bushy leaves of the squash acted as a living mulch, cooling the soil and helping it to retain moisture. The prickly squash leaves also helped to deter unwanted garden pests, such as raccoon, deer and rabbit. Bush types of summer squash are excellent for this trio of companion plants, rather than vining and sprawling types. Keep reading to learn more about summer squash plants.
Summer Squash Types
Most summer squash today are varieties of Cucurbita pepo. Summer squash plants differ from winter squash because most summer squash varieties bear their fruit on bushy plants rather than vining or sprawling plants like winter squashes. Summer squashes are also harvested when their rinds are still soft and edible, and fruit is still immature.
Winter squashes, on the other hand, are harvested when the fruit is mature and their rinds are hard and thick. Because of the thick rinds of winter squash vs. the soft rinds of summer squash, winter squash has a longer storage life than summer squash. This is actually why they are known as summer or winter squash – summer squashes are enjoyed only for a short season, while winter squash can be enjoyed long after harvest.
There are also different summer squash types. These are usually categorized by the shape of the summer squash. Constricted neck or crookneck squashes usually have yellow skin and a curved, bent or angled neck. Likewise, straightneck squashes have straight necks. Cylindrical or club-shaped squashes are typically green, but can be yellow or white. Some, but not all, zucchini and cocozelle varieties of summer squash fall into the cylindrical or club-shaped categories. Scallop or patty-pan squashes are round and flat with scalloped edges. They are typically white, yellow or green.
