San Marzano Italian Paste Tomato Seeds

San Marzano Italian Paste Tomato Seeds produce the classic Italian paste tomato famous for its rich flavor, dense flesh, and exceptional cooking quality. A more rectangular and slightly later-ripening version of Roma, San Marzano offers bright red, meaty fruits with an extra-high solids content that makes them ideal for canning, slow simmering, and traditional tomato sauces. Their smooth texture and low seed count help them cook down into a thick, flavorful base prized by chefs and home gardeners alike.

These indeterminate vines grow tall and vigorous, often reaching 6–8 feet, and will benefit from staking or strong support throughout the season. Fruits average about 3½ inches long and are produced steadily from midseason onward, providing dependable yields of uniform, classic paste-type tomatoes. Whether you’re making homemade marinara, roasting tomatoes for freezing, or stocking your pantry with jars of tomato goodness, San Marzano remains one of the most trusted and flavorful paste varieties you can grow.
