These roses were introduced from Japan to be used as root stock for hybrid roses. It escaped. Now the multiflora rose is considered an invasive alien in many areas, and even a noxious weed in a few places. It grows into trees, over fences, throughout pastures. We have them everywhere. I do love them, anyway, and their scent is heavenly!
It blossoms in late spring with white flowers (rarely pink) approximately 1 inch in size. The plant can reseed itself, propagate new plants anywhere the canes touch soil, and birds that eat the rose hips help to spread them. Their range is extensive and growing with the general exception of the Rocky Mountains and deserts.
Once multiflora roses are established, control is difficult and they can crowd out native plants.
This picture was taken May 26, 2013, in Green Lane, PA, along the Unami Creek where they thrive. The camera was a Canon T4i with a Tamron macro 1:1 lens.
