Both the Arboretum and Perennial Demonstration Garden at Colorado State University have several established areas for evaluation trials. These areas provide a strong foundation for scientific plant evaluation for the Rocky Mountain Areas and High Plains area. The grant from CHREF for 2021 will help us to create more space for evaluation of woody plants in an area south of Horticulture Center on the CSU campus. It will also allow us to help maintain the arboretum and perennial garden and also improve the website and educational outreach of the arboretum and perennial garden. Grant also will help to cover cost in producing published reports based on our annual evaluation along with herbaceous perennial collection and updating our website.
