Summary 7
Rosa multiflora, commonly known as multiflora rose,baby rose,Japanese rose,many-flowered rose,seven-sisters rose,Eijitsu rose, is a species of rose native to eastern Asia, in China, Japan and Korea. It should not be confused with Rosa rugosa, which is also known as "Japanese rose".
Ecological threat in the united states 8
Multiflora rose is extremely prolific and can form impenetrable thickets that exclude native plant species. This exotic rose readily invades open woodlands, forest edges, successional fields, savannas and prairies that have been subjected to land disturbance.
Description and biology 9
- Plant: multi-stemmed shrub, sometimes climbing vine, with arching stems and recurved thorns.
- Leaves: divided into five to eleven sharply toothed leaflets; leaf stalks with fringed stipules (paired wing-like structures).
- Flowers, fruits and seeds: clusters of showy, fragrant, white to pinkish, 1 in. wide flowers appear during May; small bright red fruits, or rose hips, develop during the summer and remain on the plant through the winter.
- Spreads: reproduces by seed and by forming new plants from the tips of arching canes that can root where they contact the ground. An average plant produces an estimated one million seeds per year, which remain viable in the soil for up to 20 years.
- Look-alikes: pasture rose (Rosa carolina); swamp rose (Rosa palustris); Allegheny blackberry (Rubus allegheniensis); flowering raspberry (Rubus odoratus). Only multiflora rose has the combination of upright arching stems and fringed stipules.
