Grown in clusters on vigorous indeterminate vines, these fruits mature to a deep red with dense, meaty flesh, minimal seeds, and thick walls that yield rich, concentrated flavor. Crack-resistant and high-yielding, San Marzano produces continuously throughout the season, delivering exceptional harvests of paste tomatoes that stretch further and cook down faster than watery slicing varieties. Whether you're making Sunday gravy, homemade salsa, or stocking your pantry for winter, this is the tomato that serious home canners and sauce makers rely on. Matures in approximately 80 days from transplant.\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: rgb(22, 76, 5);\"\u003e\u003cstrong\u003eGermination Rate: 81%. Test Date: 8\/25.
