Costata Romanesco Zucchini (Heirloom 52 Days)

Old Italian heirloom. Fruits have attractive, flecked green-and-white skin and deep ribs. This zucchini is known for its fine eating quality- nutty flavor and great texture, cooked or raw. Harvest at 6- 8”; oversized fruits are great for stuffing. Semi-vining plants are larger and produce less than hybrids, definitely worth growing for the authentic heirloom flavor.
