Description

San Marzano (Indeterminate) Tomato is a legendary Italian paste tomato celebrated for its rich, sweet flavor, low acidity, and dense, meaty texture. The elongated, plum-shaped fruits have fewer seeds and thicker flesh than standard slicing tomatoes, making them the gold standard for sauces, pastes, and canning. Its deep red color and classic flavor profile have made it a staple in authentic Italian cooking for generations.

San Marzano delivers a bold yet balanced tomato flavor that intensifies when cooked, producing a naturally thick, smooth sauce without needing heavy reduction. The fruits hold their shape well during processing while still breaking down into a velvety consistency. While excellent fresh, this variety truly shines when simmered into sauces, soups, and roasted dishes.

Highly productive indeterminate vines continue growing and producing fruit throughout the season, requiring support and regular pruning for best results. They thrive in warm conditions and reward growers with steady clusters of high-quality paste tomatoes over a long harvest window. If you’re looking for an authentic sauce tomato with exceptional flavor, texture, and culinary reputation, San Marzano is an essential garden classic.

• Type: Open-pollinated annual (indeterminate)
• Start seeds: Indoors 6–8 weeks before last frost

Tomatoes thrive in warm weather and rich, well-drained soil with consistent moisture and steady warmth. Transplant seedlings outdoors only after all danger of frost has passed and nighttime temperatures remain reliably warm. Indeterminate varieties benefit from staking, trellising, and regular pruning to improve airflow and fruit production. Harvest fruits when they reach full deep red color and have a slight give to the touch. Regular picking encourages continued flowering and sustained production throughout the growing season.
