They are vigorous, thriving on minimal maintenance, and tend to be extremely hardy and disease-resistant. It should be noted however, that there is variability within species. Some may be more tolerant than others. They range in size from ground cover types to very large upright growers and climbers. Their flowers can be very large and single or small and in clusters.
Colors range from white to pink to crimson.
Species roses often have relatively simple, 5-petaled flowers followed by very colorful hips that last well into the winter, providing food for birds and winter color. Almost all are once-blooming in early summer. Perhaps the most familiar species for sale today is Rosa rugosa because of its superior hardiness, disease resistance, and extremely easy maintenance. The species has been widely hybridized. Species roses may not be for everyone.
