Family

Botanical Name

ROSA multiflora

Plant Common Name

Baby Rose, Multiflora Rose

General Description

A parent of the Polyantha roses and numerous "rambling" roses, this large rampant deciduous shrub from East Asia is a troublesome weed in the United States and numerous other locales. The long, arching, clambering stems of this hardy shrub are armed with vicious curved thorns which enable it to cling to and engulf other plants as large as medium-sized trees. Compound leaves with 5 to 11 toothed oval leaflets alternate along the stems. A fringed, caterpillar-like stipule with long hair-like teeth clasps the base of each leaf stalk. Fruit-scented clusters of small white roses open in late spring, followed by small berry-like fruits which ripen to red and persist into winter. The fruits are eaten and disseminated by birds. This thuggish shrub thrives in full sun to partial shade in many different soils. It is listed as an invasive weed in many areas of the United States as well as in other countries. Nurseries often graft rose cultivars onto multiflora rootstock. For methods of controlling Rosa multiflora see http://www.fs.fed.us/database/feis/plants/shrub/rosmul/all.html#FIRE%20EFFECTS.
