Since 1971, Colorado State's Plant Environmental Research Center has studied the variables that affect the performance of different annual plant cultivars within the environment of the Rocky Mountains. Plants are evaluated by by faculty, horticulturalists and local Master Gardeners. The best part? The garden is open to the public and might be the most beautiful space in the entire city of Fort Collins.


  • Some of the winning flower's from the school's annual flower show.
  • Beautiful display of over 50 different types and colors of flowers.

The W. D. Holley Plant Environmental Research Center (PERC), located at 630 W. Lake Street on the Colorado State University campus, has been in operation since 1971. In 2000, the Annual Flower Trial Garden was moved from its site at PERC to the park on Remington Street that is just across from the newly remodeled CSU Center for Arts, which was the old Fort Collins High School building.

The outdoor display and test areas at the Annual Flower Trial Garden were established to allow students, researchers, industry representatives, homeowners and extension personnel to learn, teach and evaluate through horticultural research and demonstration projects conducted in the unique environmental conditions of the Rocky Mountain/High Plains region.
