The National Grass Trials at Colorado State University has attached the final 2015 data with both a full report and averaged data. All of the grasses did well this year, despite numerous adverse weather conditions such as extreme weather event where temperatures plunged from the mid-50’s to -16 degrees F in 24 hours in November 2014. We also had an abnormally wet May 2015, with over 6 inches of rain that month and I late hard frost on May 10. The best performers for 2015 were Shenandoah and Heavy Metal , Panicum virgatum (Switchgrass) cultivars and Schizachyrium scoparium ‘The Blues’. No disease or pests were noted in the three trial years, with minimal plant loss.
