85 Days to maturity (from transplant). Solanum lycoperscium. San Marzano (Indeterminate) Tomato Seeds. Non-GMO, annual, open-pollinated, heirloom, indeterminate, paste tomato. Often compared to the famous Roma tomato in terms of shape, size, and flavor, San Marzano seeds grow a traditional Italian cultivar commercially produced throughout the 20th century.
