Species of flowering plant in the rose family Rosaceae

Rosa multiflora (syn. Rosa polyantha) is a species of rose known commonly as multiflora rose, baby rose, include the varieties:
Rosa multiflora var. adenochaeta (Koidz.) Ohwi
Rosa multiflora var. cathayensis Rehder & E. H. Wilson. Flowers pink, to diameter. Rosa multiflora var. multiflora. Flowers white, diameter.

Rosa multiflora is grown as an ornamental plant and also used as a rootstock for grafted ornamental rose cultivars. In eastern North America, Rosa multiflora is considered an invasive species. It was originally introduced from Asia as a soil conservation measure, as a natural hedge to border grazing land, and to attract wildlife. It is readily distinguished from American native roses by its large inflorescences, which bear multiple flowers and hips, often more than a dozen, while the American species bear only one or a few on a branch. In some regions the plant is classified as a noxious weed. In grazing areas, it is generally considered to be a serious pest, though it is considered excellent fodder for goats. The hips of the plant are edible.

The targeted removal of multiflora rose often requires an aggressive technique, such as the full removal of the plant in addition to the root structure. Pruning and cutting back of the plant often leads to re sprouting. Two natural biological controls include the rose rosette disease and the rose seed chalid (Megastigmus aculeastus var. nigroflavus). Patches of introduced multiflora rose in Pennsylvania are displaying symptoms of rose rosette disease, which can lead to decline and death.
