Source Identified Seed

Natural SelectionsTM native seed is certified as Source Identified or “Yellow Tag” seed. This means it is certified to source by the Iowa Crop Improvement Association in accordance with standards set by the Association of Official Seed Certifying Agencies (AOSCA). AOSCA source-identified seed standards provide a ‘fast-track’ alternative release procedure when:

  1. inadequate commercial supplies for a species exist
  2. propagation material from specific ecotypes is needed for ecosystem restoration
  3. there is high potential for immediate use
  4. there is limited potential for commercial production beyond specific plant community sites

Iowa sources of certified seed are published annually in the Iowa Seed Directory
