Squash is a seasonal vegetable. It is very susceptible to frost and heat damage, but with proper care, it will produce a bumper crop with very few plants.
There are many varieties of summer squash to choose from, including zucchini. The main difference between winter and summer squash varieties is their harvest time; the longer growing period gives winter squash a tougher, inedible skin. Here are their various botanical names: Cucurbita pepo (Summer squash/Zucchini), C. maxima (True winter), C. pepo (Acorn, delicata, spaghetti) , C. moschata (butternut).
