Kingdom: Plantae, Division: Tracheophyta, Class: Magnoliopsida, Order: Rosales, Family: Rosaceae, Genus: Rosa, Species: Rosa multiflora · Rosaceae (Rose family) · Pinnately compound, deciduous shrub
Species
Rosa multiflora
Leaf Type
Pinnately compound, deciduous shrub
Family
Rosaceae (Rose family)
Shape
Ovate to elliptical leaflets with acute tips
Size
The entire leaf measures approximately 5 inches long, while individual leaflets range from 1 to 2.5 inches long, falling well within the typical range for the species.
Margin
Serrate (sharply toothed)
Arrangement
Alternate on the stem, with a distinctive winged stipule fused to the base of the petiole
Rarity
Very Common in its introduced range, frequently forming dense, impenetrable thickets.
Color & Pattern
Dark olive green on the upper surface, paler and slightly duller on the underside. No variegation or abnormal markings are present.
Venation Pattern
Pinnate venation with a prominent central midrib and clearly visible lateral veins branching outwards.
Texture & Surface
Smooth (glabrous) to slightly pubescent along the veins on the lower surface, with a matte finish typical of pressed herbarium specimens.
Description
Rosa multiflora is a vigorous, scrambling deciduous shrub with long, arching stems armed with sharp prickles. It produces abundant clusters of small, fragrant white or pinkish flowers in late spring, followed by small red fruits known as rose hips that persist through winter.
Key Features
The most diagnostic feature is the fringed or comb-like (pectinate) stipule fused to the base of the leaf petiole, combined with clusters of numerous small white flowers and pinnately compound leaves usually bearing 5 to 9 leaflets.
Habitat
Thrives in disturbed areas, forest edges, old fields, and along roadsides. Prefers full sun to partial shade and adaptable to a wide range of soil types.
Geographic Range
Native to eastern Asia (Japan, Korea, China). Introduced to North America and Europe as an ornamental and for erosion control, where it is now widely naturalized and often invasive.
Condition Notes
The pressed and dried leaf specimen is in Good condition, showing intact leaflet margins, well-preserved coloration, and minor handling wear typical of botanical mounts.
Interesting Facts
Originally imported from Asia in the 1860s for use as rootstock for ornamental roses and later promoted heavily by conservation agencies as a living fence for livestock and wildlife cover, it has since become a severe ecological pest.
Medicinal & Uses
Rose hips are exceptionally high in vitamin C and can be used to make teas, jams, and syrups. Historically used in traditional herbal medicine, though the plant is primarily managed today for removal due to its invasive tendencies.
Ecological Role
Provides cover and nesting sites for birds, and the hips are eaten by various wildlife. However, its dense thickets aggressively outcompete native vegetation and reduce overall plant biodiversity.
Similar Species
Can be confused with native roses such as the Swamp Rose (Rosa palustris) or Pasture Rose (Rosa carolina), but can be distinguished by its distinct fringed stipules and large clusters of numerous small flowers.
Foraging Tips
Look along woodland edges and abandoned pastures. The characteristic fringed stipules at the base of the leaf stalk are the definitive field mark to separate it from native rose species.
Toxicity Warning
Non-toxic. Rose leaves and hips are generally safe, though care should be taken to avoid sharp prickles on the stems in the field.
