Leaflets in arrangement of 7 to 9, each leaflet fingernail size, serrated on edges, and longer than wide.

Origin--Japan, Korea, eastern China
Distribution
Frequently found at low elevations in all counties along road sides, fencerows, stream sides, forest edges, and unmaintained fields.
Threat
Forms single species thickets crowding out native plants, especially at stream sides.
Seeds are spread by birds and other animals.
Control
Mowing can keep invasions in check.
Pulling up small plants can be effective if repeated to control root sprouts and seedling germination.
Chemical control involves foliar sprays (glyphosate, triclopyr @ 2 to 3%), cut stump treatment of the same sprays (@ 25% concentrations), and basal bark treatment (triclopyr @ 25% mixed with horticultural oil).
Similar Plants
Native roses. Multiflora rose has a feathery or comb-like projection (stipule) at the base of leaf stems. Other roses have this projection, but lack the feathery or comb-like characteristic.
