Zucchini or courgette is a summer squash which can reach nearly a metre in length, but is usually harvested immature at 15 to 25 cm (6 to 10 in). In Britain and Ireland a fully grown zucchini is referred to as a marrow.
Along with certain other squashes and pumpkins, it belongs to the species Cucurbita pepo. Zucchini can be dark or light green. A related hybrid, the golden zucchini, is a deep yellow or orange color.
