Colorado Green Now

Dr. Jim Klett, CSU professor, department of horticulture and landscape architecture, believes these six plants shown to be successful in Colorado CSU trials should be used more in landscapes. Horticulture and forestry students help maintain the test sites with support from Colorado Horticulture Research and Education Foundation (CHREF), J. Frank Schmidt Charitable Trust, Bailey Nurseries, Inc., Colorado Agriculture Experiment Station and numerous local and national nurseries. Visit these woody plants in person in Fort Collins or see more in the May/June issue of Colorado Green magazine.
