Feral Farm
Certified Organic by CCOF
Seed grower since 2015
I started growing seed commercially as an apprentice at the Organic Farm School in the Puget Sound in Washington. I already loved growing vegetables, but taking a plant all the way through its life cycle felt like a special kind of honor, and I quickly saw the value in sustaining organic, important, and rare plant varieties and participating in sustainable food systems in this way. I moved to Oregon in 2015 and have been growing my organic seed farming business over the last four seasons by renting land from existing farms and slowly taking on higher volumes and more varieties. I’m currently growing 1.6 acres of certified organic seed crops and heirloom garlic.
