These San Marzano seeds were easy to grow, and the tomatoes taste exactly like the ones I remember from Italy. Perfect for sauces and fresh salads. Highly recommend for anyone who loves heirloom varieties.
I planted these seeds indoors first, and nearly all of them sprouted. The seedlings are strong, and the fruits are long, juicy, and full of flavor. Definitely worth the purchase.
Growing heirloom tomatoes takes some patience, but these seeds delivered. The fruits are dense, sweet, and perfectly balanced for pasta sauces. A must-have for home gardeners.
The seeds arrived in good condition and sprouted reliably. The plants grew strong, and the first harvest was impressive. Excellent for anyone who loves garden-fresh tomatoes.
I grew these tomatoes in my backyard garden. The flavor is rich and tangy, and they hold up well for cooking sauces. I will definitely buy these seeds again next season.
