These seeds took a little time to germinate, but once they did, the plants thrived. The tomatoes are juicy, sweet, and perfect for canning. I�m already planning next year�s garden with more of these.
I was looking for authentic San Marzano tomatoes for pasta sauce, and these seeds delivered. The fruits are meaty and flavorful, just like the ones from Italy. Very happy with my purchase.
I planted these in late spring and was surprised at how many tomatoes each plant produced. They are deliciously sweet and perfect for fresh salads. Definitely worth the effort.
I like that these are non-GMO and heirloom. The plants were healthy, and the tomatoes are firm yet juicy. My family loves them, especially in homemade sauces.
The seeds germinated well, and the plants grew strong and tall. The tomatoes taste fantastic�rich and sweet, just what I hoped for. I�ll be buying them again next season.
