The focus of this research was to evaluate genotypes for cold-tolerant germination from wild switchgrass (Panicum virgatum L. ) populations collected in the Northeast USA. Switchgrass nurseries were established in 2008 and 2009 with seed collected from native stands of switchgrass in the Northeast USA between 1991 and 2008. https://cascadianaturales.shop/product-category/grooming-supplies/
