San Marzano is a legendary Italian plum tomato variety known for its elongated shape, thick walls, and low seed count. Its rich, sweet flavour and dense flesh make it a top choice for sauces, pastes, canning, and Mediterranean cooking. Originally from the volcanic soils near San Marzano sul Sarno in Italy, this heirloom variety thrives in warm climates and sunny gardens, continuing to produce fruit throughout the season when staked and cared for properly.
