This evergreen shrub has arching stems and recurved thorns. Leaves are alternate and pinnately compound with toothed margins. Each leaflet is 1 - 3 in. long. Flowers occur in small clusters, and are white and 5-petaled, with many yellow anthers in the center. Hips (fruit) are round and fleshy, 0.25 - 0.4 in. in diameter, green or yellow but ripening to red.
Individual plants of Macartney rose form dense clumps several yards in diameter and as high as 10 feet, later coalescing to form dense thickets.
Macartney rose forms dense thickets, displacing native grasses such as the endangered white bladderpod, and altering native wildlife habitat. Greatly decreases forage productivity of cattle pasture and adds to the economic burden of land managers.
