Yellow crookneck squash is one of the many cultivars of Cucurbita pepo,[1] the species that also includes some pumpkins and most other summer squashes. The plants are bushy,[1] and do not spread like the plants of winter squash and pumpkin.[2] It is most often used as a summer squash, and is characterized by its bumpy,[2] yellow skin and sweet yellow flesh, as well as its distinctive curved stem-end or "crooked neck".[3] It should not be confused with crookneck cultivars of Cucurbita moschata, such as the winter squash 'Golden Cushaw',[4] or the vining summer squash 'Tromboncino'.[1] Its name distinguishes it from its close relative, the yellow summer squash, which has a straight neck.

Yellow crookneck squash are generally harvested immature, when they are less than two inches in diameter,[2][3] since the skin toughens and the quality degrades as the squash reaches full maturity.[5]
