Diversity of Roses

Roses have grown in gardens for thousands of years. Gardeners have taken advantage of the natural variation within wild rose species (the ancestors of all modern hybrid roses) to breed plants that exhibit a range of colors, shapes, and fragrances. Breeding and hybridizing roses has resulted in hundreds of species and tens of thousands of cultivars.

The American Rose Society developed a system for classifying and organizing roses. Three categories emerged: Species Roses, Old Garden Roses, and Modern Roses.
