Source ID.

Rainier Seeds has been producing source identified ecotypes for more than 15 years. We locate and identify a native seed source, acquire permission to collect, harvest and process. The Association of Official Seed Certifying Agencies then verifies the seed as “native.” We apply for certification of privately-collected seed and send a “Germplasm Collection Form” to OASCA, documenting the specific location where the seed was collected.
