  • A thorny shrub or woody vine with arching branches that give it a fountain shape. Plants are densely spreading, and may reach 15 feet tall. Deciduous.

The Leaves:

  • alternate
  • pinnately compound
  • 5 to 11 leaflets
  • serrated
  • elliptic
  • 1-1.5 inches long
  • smooth, dark above
  • small hairs and pale below
  • feathery or comb-like margin on stipules at base of leaf stalks

The Stem:

  • red to green
  • glabrous
  • long
  • arching
  • older stems woody
  • recurved thorns

The Flowers:

  • Fragrant, white or pink five-petaled flowers with many stamens. Blooms from May to June.

The Fruits:

  • red fruit (rose hips)
  • mid to late summer
  • spherical
  • 0.25- 0.3 inches in diameter

The Habitat:

  • pastures, open disturbed areas, roadsides, vacant lots
  • gardens, reverting fields
  • woodland borders, hedgerows, and woods

Dispersal:

  • seeds are dispersed by birds

Key ID Features:

  • alternate
  • 5-11 serrated leaflets
  • dark above, pale below
  • feathery or comb-like stipule at base of leaf stalk
  • fragrant white or pink flowers
  • rose hips red

Similar Species:

  • Scotch rose (Rosa spinosissima) has many narrow, needle-like thorns on its branches
  • Memorial rose (R. wichuraiana) is more of a low-growing rose that can cover the ground
  • Multiflora rose is the only rose that has a feathery or comb-like fringe at the tips of its stipules (green leaf-like structure at the base of each leaf stalk).

Notes:

  • The Multiflora Rose creates a living fence due to its dense growth, and it prevents native plants from establishing. The plant is spread great distances since birds consume the rose hips and spread the seeds
