Multiflora Rose
Identification:
Multiflora rose is a thorny, perennial shrub with arching stems (canes), and leaves divided into five to eleven sharply toothed leaflets. The base of each leaf stalk bears a pair of fringed spines. Beginning in May or June, clusters of showy, fragrant, white to pink flowers appear, each about an inch across. Small bright red fruit known as hips develop during the summer, becoming leathery, and remain on the plant through the winter.
Multiflora rose is extremely prolific and can form impenetrable thickets that exclude native plant species. This exotic rose readily invades open woodlands, forest edges, successional fields, and meadows that have been subjected to land disturbance.
Control:
Multiflora rose is most effectively controlled by recognizing its appearance early and removing isolated plants before they begin to produce seed. Hand pulling is effective in small infestations. Make sure to wear gloves and long sleeves as the plant is quite thorny. Remove the entire root section or re-sprouting will occur. Mowing 6 times per growing season for 3 to 4 years has proven effective. Chemical treatment to the stump is acceptable for larger infestations.
