$ 2.25 Sold Out

British Heirloom. The Green Vegetable Marrow Summer Squash is a very old variety that has always been popular in England. Bush plants produce green oval fruits that can be used in all the usual ways. When bigger, the squash are often stuffed. An English customer mentioned bread crumbs, onions, and nuts for stuffing – I’d add a bit of hot Italian sausage.
