Description

Can a tomato be a celebrity? Ask the San Marzano Tomato—if you can get past its bodyguards. One commercial grower proclaims it the “gold standard for taste.” Martha Stewart devoted an entire blog post to it. Certified tomatoes from Italy are regulated. It even has its own Wikipedia page. But at the end of the day, it’s still just a tomato. One that’s longer and thinner than other plum/paste tomatoes, with exceptional tomato flavor, meaty and thin skinned for slicing, few seeds and fleshy for saucing, and very high yields. We’ve joined the fan club. How about you?

    OUR PLEDGE TO YOU

    Agriculture and seeds provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations.

    For the benefit of all farmers, gardeners and consumers who want an alternative. We pledge to you that we do not knowingly buy or sell genetically engineered seeds or plants.  The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political, and cultural threats.

    We wish to support agricultural progress that leads to healthier soils, genetically diverse agricultural ecosystems and ultimately healthy people and communities.

    We do not buy - OR - grow any seed from large corporations that make Genetically Engineered seeds.  We don't touch that stuff and we never will.

    The seeds we offer aren't like varieties you'd typically find at a garden center. 

    Every variety we offer is 100% OP (open-pollinated).  Open-pollination means that you can safely save the seed after harvest and preserve a collection of heirloom seed for many generations to come.

    To make it perfectly clear ... Our seeds do not contain any exogenously inserted embryogenesis deactivator genes caused by human intervention.
