Celebrate OSA: Support the Annual Appeal Today!

Weaving Power Into the Hands of Growers Together!

Help us reach our Annual Appeal goal of $150,000! These funds empower growers in every research plot, summit gathering, and policy win.  

Together, with partners across the nation and around the world, OSA builds more sustainable and equitable food and fiber systems.

  • Advocacy Work protects seed sovereignty at the local, regional, and national levels.
  • Research and Education Programs connect organic seed resources with growers and plant breeders.
  • Outreach Efforts build power through convening seed communities and activating new collaborations.  

Thank you for joining us in this season of growth!

Celebrate the power of seed and order a t-shirt or a tote bag for yourself or the seed lovers in your life. This year’s Annual Appeal artwork depicts purple sprouting broccoli (Brassica oleracea var. italica), a crop improved by OSA for organic growers. 

Shirts are printed on 100% organic cotton, and totes are made from recycled materials.
