Adaptive Seeds was established in 2009 by Andrew Still and Sarah Kleeger. We are a certified organic, farm based seed company near Sweet Home, Oregon. We steward rare, diverse and resilient seed varieties for ecologically-minded farmers, gardeners and seed savers. Our seed is adapted to the Pacific Northwest and other short season northern climates. We sell only public domain, open pollinated (OP) seed, as well as diverse gene pool mixes. All of our seed is grown by us or a few regional friends who help with isolation needs. If we didn’t grow it, we say who did in the variety description. For more information about our growers, see below.

NONE of our seeds are proprietary hybrids (F1), patented, PVP, or genetically modified (GMO). All of our seed is grown without chemical fertilizers, herbicides or pesticides, and NONE of it is treated.

Organic Certification

Our farm has been Certified Organic by Oregon Tilth since 2013.

Since we finished our certification process, all seeds that have been grown at Adaptive Seeds are certified organic. In 2015, we added the handler’s scope to our organic certification, enabling us to sell seed purchased from certified organic growers as certified organic seed. This means that 99% of our catalog is certified organic! There are only a few varieties listed in our catalog without the organic logo and they were produced by farms that have chosen not to certify for one reason or another, or are currently working towards certification. We appreciate your understanding and if you ever have a concern, just ask. Here’s a PDF of our most recent certificate: Adaptive Seeds Organic Certification.  And here is our Untreated Seed Statement.

Our Seed Priorities


– Rare and heritage varieties
– Oregon and Northwest-bred
– Public domain, modern varieties
– Diverse genepool mixes and landraces
– Open pollinated varieties for commercial growers
– Winter garden varieties
– Early maturing and northern adapted varieties
– Highly nutritious staple foods

We guarantee that every seed lot we sell is regularly germination tested and has been found to exceed industry and federal germination standards.

All Brassica family seed lots have been tested and found negative for blackleg (Phoma lingam) as required by the Oregon Department of Agriculture.

Why Open Pollinated (OP) & Regional?

Hybrid seeds are beneficial mostly as monocrops. It seems the goal of the corporate produced hybrid is to sever the seed’s relationship to the natural world, and profit from a corrupt short term economic model. We believe proprietary control schemes such as hybrids (F1), patenting, PVP, and trademarking are stifling resilient innovation and diversity. Proprietary hybrids are the single biggest contributor to the erosion of agricultural biodiversity regionally and worldwide. Open pollination encourages diversity and resilience. It is akin to open source. Unlike hybrids, open pollinated varieties become adapted to the area in which they are grown and have been shown to outperform imported seed. If we are to approach true food freedom, it must rest on a foundation of open pollination.

Open Source Seed Initiative

Open Source Seed Initiative

We are thrilled to be able to encourage open access to biodiversity as a partner seed company and participating breeder with the Open Source Seed Initiative (OSSI). OSSI is dedicated to maintaining fair and open access to plant genetic resources worldwide by offering a new way to save and exchange seed that ensures the seed will remain free of patents, licenses, and other restrictions.

Varieties that are registered as OSSI seed are accompanied by the pledge (see below), which prohibits the varieties or their derivatives from being patented or licensed in ways that can restrict use. The OSSI Pledge also requires that any subsequent distributions of OSSI seed, or of derivatives bred from OSSI seed, be accompanied by the pledge. In this way, OSSI intends to develop an expanding pool of genetic resources that are available now and in the future for unrestricted use by scientists, farmers, and gardeners. This pledge is a commitment to foster unfettered exchange of germplasm and the freedom to use the material for any purpose, with the single proviso that by accepting the pledge the user commits to allowing others freedom to use the material or derivatives of the material.

Varieties listed in our catalog with the OSSI logo have been designated open source by the people who bred them and are registered as OSSI-Pledged seeds. Breeders that participate include Carol Deppe, Frank Morton, Dave Podoll, and us here at Adaptive Seeds. Free the seed! For more information:

The Pledge: You have the freedom to use these OSSI-Pledged seeds in any way you choose. In return, you pledge not to restrict others’ use of these seeds or their derivatives by patents, licenses or other means, and to include this pledge with any transfer of these seeds or their derivatives.

What is The Seed Ambassadors Project?

The Seed Ambassadors Project (SAP) began as a small group of Oregon-based seed stewards with the principal goal to increase the diversity of locally adapted varieties in our bioregion and disseminate this resource in order to further local food system durability worldwide. We see locally adapted varieties as the foundation of the durable and resilient local food system that we are helping to create. Adaptive Seeds naturally evolved out of SAP as we found ourselves seeking more ways for our seeds to reach people.

A few of us Ambassadors spent several winters traveling through Europe and Asia sharing seed, collecting and exchanging varieties, and teaching seed saving skills. We have collected over 800 varieties of food plants, most of which were not available in the US when we acquired them. Many are now available in this catalog and others are grown in our preservation gardens. We also contribute to seed swaps, and teach classes on seed saving, winter gardening, and locally adapted seeds.
