Heirloom. Developed by the USDA vegetable station in Charleston, South Carolina in 1960, Marion is open-pollinated and well adapted to the South. A Rutgers type, but earlier and more disease-resistant. Indeterminate vines bear smooth, deep-globed, and crack resistant fruit all season. High yielding and vigorous, so be sure to stake or cage. A great slicing tomato. Resistant to fusarium wilt (F) and gray leaf spot (St).
