Costoluto Genovese Tomato Seeds (Aimers International) Heirloom Vegetable. Variety originated in Italy. Deep red, heavily ribbed somewhat flattened fruit to 200 g (7 oz) will not win a beauty contest. It is the delightfully tangy, richly flavoured taste that is a winner! Superb fresh, sauced, canned, juiced or preserved. Indeterminate growth. Matures in 90 days.
