Germination Information

Pre-treatment: Inoculating soil with mycorrhizal fungi, especially when sites are highly degraded and unlikely to have extant mycorrhizal populations

Establishment: This species was previously classified as a variety of alkali sacaton (Sporobolus airoides). It is found from 2,000-5,000 feet along river banks and dry, sandy, open sites. Its range has significantly declined over the past century--it now occurs in less than 5% of its original range.
