Landscape Plant Research
The Plant Environmental Research Center (PERC) has been in operation since 1972. Major changes are planned for PERC due to the construction of a new stadium for the university. The greenhouses will be demolished around July 1st and new greenhouses and some research areas will be built a few blocks to the south east on Center Avenue. Most of the outdoor area will remain at its current location although some will be relocated to the new site on Center Ave. The perennial garden and the arboretum will remain. Plans are be developed to hopefully renovate the remaining area.
The PERC outside grounds were established so students, researchers and other interested persons can observe horticulture plant materials “in action.” The grounds are free and open to the public any day during daylight hours. The Plant Environmental Research Center is located at 630 West Lake Street on the southwest corner of the CSU main campus. The Annual Flower Trial Garden which used to be located at PERC is now located approximately 0.75 mile directly to the east at the corner of College Avenue and West Lake Street.
There are no state funds directly allocated for the operation of the grounds at PERC. The Colorado State University Agricultural Experiment Station, Cooperative Extension Service and Department of Horticulture and Landscape Architecture assist by partially funding the salaries and research projects of many of the faculty involved at PERC. Financial assistance and/or plant materials for the ground areas have come from a number of sources including state horticultural professional associations, Colorado Nursery Research and Education Foundation, Colorado Floriculture Foundation, Specialty Crops Program, Colorado Garden Show, Inc., nurseries and seed companies across the nation and other horticulture-related industries.
Most plant material is labeled for easy identification. Woody plants have I.D. tags on the north side.
If you desire more information about some particular plant material or planting, please contact the professor in charge of that area.
