Heirloom Squash varieties in fall setting. - St. Clare Heirloom Seeds

Flavor, flavor, flavor! One of the first reasons people grow open-pollinated or heirloom seeds is the flavor. Hybrids are bred for many characteristics such as uniformity (in shape or harvest time), high yields, withstanding rigors of transport, etc. But, sadly in the breeding process the desirable characteristics like flavor and nutritional value suffer. There’s truly nothing as delicious as a sun-ripened home-grown heirloom tomato. You tomato lovers out there know just what I mean when I say we suffer each winter, waiting for the first delicious tomatoes of the next garden season. 🙂

Heirloom Non GMO Scarlet Nantes Carrots - St. Clare Heirloom Seeds

Question: I am looking at starting my garden and collection of Heirloom Non-GMO Seeds but want to ensure they are Non-GMO and Heirloom. In looking through your seeds for sale, some specifically say that and others do not. Are ALL of the seeds Heirloom Non-GMO seeds or only the seeds labeled that way in the description?

St. Clare Heirloom Seeds are proud signers of The Safe Seed Pledge: “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 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 feel that genetically engineered varieties have been insufficiently tested prior to public release. More research and testing is necessary to further assess the potential risks of genetically engineered seeds. Further, we wish to support agricultural progress that leads to healthier soils, genetically diverse agricultural ecosystems and ultimately healthy people and communities.” ×
