Unfortunately, this monster plant was brought over to North America from Japan, and it is native also to Korea. This Japanese Multiflora Rose was brought over to be a root stock for cultivated rose scions. It was also spread around in parts of the USA by the old Soil Conservation Service, with the mistaken idea it would be good for soil stabilization. They should have chosen some native species as Gray Dogwood to do a better job and not allow such an invasive species to go crazy in becoming one of the major shrub species in the Midwest, Mid-Atlantic, Northeast, and some of the northern South, growing wild along forest edges and in fields. It even likes to invade residential yards. When it is leafed out and blooming it can look good sometimes. It has the habit of partially climbing up into trees with long, vine-like branches. As a Rose can be, it is nasty to touch with all of the thorns. I do enjoy cutting this species down with loppers and shears and then axing the base area into the ground when I work in winter time at removing or lessening invasive woody plants, as volunteer work. I do the same with its common companions of Amur honeysuckle, Autumn-Olive, Winged Euonymus, Privets, Common Buckthorn, Oriental Bittersweet vine, and Japanese Honeysuckle vine. I'm glad the new Rose Rosette Disease is attacking it, (I wish the deer would eat it), and where this Japanese Rose is common, the disease is also more common to attack cultivated roses. I believe native species roses as Virginia Rose, Carolina Rose, Swamp Rose, etc. are resistant.
