Multiflora rose flowers

Multiflora rose (Rosa multiflora)

Thorny, thicket-forming shrub with wide, arching or climbing canes and stiff, curved thorns. Can reach 10-15’ tall and 9-13’ wide. Typically more spreading than erect.


Regulated areas of multiflora rose
Multiflora rose is Restricted (Orange counties)

Other names for this plant include:

  • Common names: Japanese rose, many-flowered rose
  • Scientific names: R. cathayensis; R. multiflora var. carnea

Ecological threat:

  • Multiflora rose invades open woodlands, forest edges, old fields, roadsides, savannas, and prairies. It can tolerate a wide range of soil and environmental conditions and full or partial sun. It does best on well-drained soils.
  • It is extremely prolific and can form impenetrable thickets that exclude native plants species.
  • Introduced from Japan in 1886 as rootstock for cultivated roses, it has been planted widely to curb soil erosion, as a living fence, and as a source of food and cover for wildlife.
  • Produces up to 500,000 seeds per year. Seeds remain viable in the soil for 10 to 20 years.

Classification in Wisconsin: Restricted

Species Assessment Groups (SAG) were assembled to recommend a legal classification for each species considered for NR 40. The recommendation for multiflora rose was based upon this literature review developed by the department.


Leaves: Alternate, pinnately compound with 5-11 small (0.5-1”) sharply-toothed oval leaflets, nearly smooth on upper surface and paler with short hairs on underside. Pair of fringed stipules (a leaf-like structure) at the base of each leaf.

Flowers: Abundant, showy, fragrant, and white to slightly pink, Flowers are ½ -1 ½” wide and form a panicle (a pyramidal, loosely branched flower cluster). Blooms mid- to late spring.

Fruits & seeds: Clusters of small (0.25” in diameter), hard, bright red fruits, or rose hips, develop in summer, become brownish-red at maturity, and remain on plant through winter. Dispersed by birds and mammals.

Roots: Stolons (horizontal stems) can root at the nodes; arching stems are capable of rooting at their tips.

Similar species: Native roses are distinguished by stipules with entire margins and slender, straight thorns. Most native roses also have pink flowers.

Mechanical: Pull or dig up small plants. Larger plants can be pulled with a chain, tractor or bulldozer. Be sure all roots are removed since new plants can develop from root fragments. Mow 3 to 6 times during the growing season for 2 to 4 years. Early spring burns can be effective in fire adapted communities, but areas must be monitored for seedlings and resprouts.

Chemical: Cut stump treatment with glyphosate. Basal bark treatment with triclopyr ester. Treat foliage of budding or flowering plants with glyphosate or metsulfuron methyl plus a surfactant. To prevent bud development the following year, treat foliage with fosamine and water solution in late summer.

Biological: Several biocontrol agents show potential: a native viral pathogen (rose rosette disease), which is spread by an eriophyid mite (P. fructiphilus); a seed-infesting wasp (M. aculeatus var. nigroflavus); and a stem girdler (Agrilus aurichalceus) (Amrine 2003).
