Tomato - San Marzano - Paste, Indeterminate

San Marzano tomato is a variety of plum tomato originating from the Campania region in Italy. It is known for its flavor and quality as a canning tomato.

Compared to the Roma Tomato, San Marzano tomatoes are thinner and more pointed. The flesh is much thicker with fewer seeds, and the taste is stronger, sweeter, and less acidic.


The San Marzano vines are an indeterminate type and have a somewhat longer season than other paste tomato varieties, making them particularly suitable for warmer climates. As is typical of heirloom plants, San Marzano is an open-pollinated variety that breeds true from generation to generation, making seed saving practical for the home gardener or farmer.
