This is not the case. Multiflora rose is thornless, and is used as root stock for almost all nursery roses.
Actually, multiflora rose is known to have thorns when matured. Looking at websites off of a Google search for "multiflora rose fact sheet," almost every page says something like this: "Multiflora roseis a thorny perennial shrub..."
In my experience, about 1 out of 20 wild specimens are thornless or nearly so. Most commonly, it is quite well-armed.
- There are some leaf images in Commons (now linked). However, this species is quite variable, and the genotypes that I know as a weed in North America look a bit different from the wild plants in Japan, especially in the leaves and the size of the flowers (smaller here).
