Comment: Rosa is the classical name for roses; multiflora refers to the profuse flowering clusters. Multiflora rose has been widely planted as an ornamental and for wildlife cover. It has escaped from cultivation and is considered a nuisance in many parts of the country. It may persist for many years.
Field identification: This plant can be readily identified by the many flowers it produces. Also, the ragged or fringed appearance of the stipules is unique.
Wildlife benefits: Multiflora rose is planted for wildlife cover. Although few animals eat the fruits of multiflora rose, it is dispersed by birds.
NWI status: UPL, FACU.
