The vegetable marrow is a large, mature summer squash — a cultivar group of Cucurbita pepo — grown to full size with a firm, ridged, green-striped rind and dense, pale, watery flesh. A staple of British and Commonwealth kitchen gardens, it is culturally distinct from the zucchini (courgette) that is simply the same plant picked young, and it is prized less for bold flavour than for its size, its mildness and its readiness to be hollowed, stuffed and baked.
