'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.

Low yield this year

Owner Response: We are sorry you had a low tomato yield this year. Check out our Tomato: Sow and Grow Guide in the "learn more" tab for some helpful tips. Sometimes the weather impacts yield, but sometimes a little organic fertilizer at the right time can make all the difference.

Great Tomatoes!

This is our third year growing these. The last two years were quite abundant -- I still have tomato sauce that I processed from last year's batch in my freezer. We have at least 9 starts from seed now, and look forward to another great year.

Great tomato

5 out of 5 stars Sep 15, 2020
This was our first year growing these as a recommendation from our son who traveled to Italy. We had 12 plants. They were meaty and we astonished at how much sauce we were able to make from them. Great flavor. Seemed to be quite healthy even in the drought conditions we had early on. A few did have blossom end rot but not enough to be a problem. We are looking forward to planting them next summer.

Best and Worst

3 out of 5 stars Sep 17, 2020
These roma tomatoes are prolific, large and meaty and beautiful! I started the seeds inside, but out of the whole packet, only one plant grew. Germination on all other seed varieties was outstanding. I'd decided not to purchase these romas again after the poor germination, but the amount of production and the quality of the tomatoes on the one tomato plant is amazing. I will order these again!

Mine were going great guns until the bed got infested with the wilt. Big luscious fruit.
