Yellow crookneck squash, a variety of summer squash
Summer squash are a subset of squashes that are harvested when immature (while the rind is still tender and edible). All summer squashes are the fruits of the species Cucurbita pepo (although not all squashes of this species are considered summer squashes). The name "summer squash" refers to the inability to store these squashes for long periods of time (until winter), unlike winter squashes.
