Thornless roses are roses that have thorns on their old, thick stems but don’t have thorns on their new stems.
Thornless roses are rarely thorn-free, but they have much fewer thorns than common roses. The reduced number of thorns on a thornless rose makes the plant safer for children and safer to work with, and gardeners are less likely to cut themselves when pruning the plant.
Thornless roses are comprised of the following groups:
- English roses
- Climbing roses
- Heirloom roses
- Hybrid tea roses
