'San Marzano' may very well be the mother of all paste tomatoes, as it is believed by some tomato aficionados to be the parent of almost all the paste tomatoes bred in the U.S. since the 1920s. For generations, Italians have cherished this large, paste tomato as the very best for sauce and canning, and when it comes to sauce, Italians would know! Vigorous vines reach 6' or more.

I am quite disappointed with this variety. The fruits are certainly bigger than a cherry tomato, but they are rather tiny for a past tomato. They also seem to be especially prone to blossom end rot. I will not be growing these again.
Owner Response: Thank you for taking the time to leave a comment. We are sorry you didn't enjoy this cultivar.
