Summer Squash refers to a variety of fruit in the species Cucurbita pepo. In this group you find scalloped squash, crookneck, straightneck, cocozelle, vegetable marrows, and zucchini.
Since ancient times, squash, beans and maize have been an integral part of the indigenous diet of the Americas and are a mainstay even today.
There are many types of ‘summer’ or ‘tender’ squash available. On our farm we grow:

Patty Pan Summer Squash is rounded with scalloped edges.
