Shrub roses and old garden roses are gaining national popularity as gardeners realize the excellent floral quality, good disease tolerance, and winter hardiness of these plants.

Some shrub and old garden roses which appear to have outstanding cultural and ornamental characteristics from trials at Colorado State University include:
These are just some of the shrub roses which appear to have good hardiness and nice ornamental characteristics based on our trials at the W.D. Holley Plant Environmental Research Center (PERC), 630 West Lake, Fort Collins, CO on the southwest side of the Colorado State University campus. You are welcome to visit PERC during daylight hours in the growing season.
