This voluntary certification program assures that the proper identity of native grasses' and forbs' reproductive material is maintained through all phases of production. Reproductive material refers to seeds, seedlings, or transplants.
Source identified material is comprised of the unselected Indiana germplasm and is considered to be relatively genetically diverse. Spence Restoration Nursery’s Source Identified seed is produced on our seed nursery properties from plants produced from our certified foundation seed collection.
Source identified plants are those grown from our source identified seed. Source identified tags are available for many of our plant species.
