Narrative
Perennial, native, warm-season grass that grows stalks from 2 to 6 feet tall with open, spreading panicles and scaly rhizomes. Flowers are wind pollinated. There are approximately 275,000 seeds per pound of seed. As the name implies, prairie sandreed is adapted to coarse textured soils. Anticipated uses include wind erosion control, dune stabilization, and water quality improvement in coastal zones of the Great Lakes Region and other sandy areas.

Pedigree
Description:
This is not a cultivar but a selected class, pre-varietal release; as defined by the NRCS. Developed through three cycles of recurrent phenotypic selection starting from four promising parental accessions. Three of these parental accessions were collected on the shores of Lake Michigan and one on Lake Huron. Selection criteria were upright growth habit, abundant seed production, and general vigor.
