About plant names...

Swamp rose is a North American native.

Identification: These shrubs are 6-8' (1.8-2.4 m) tall, with multiple, thorny stems. Thorns are widely spaced, single or sometimes paired, and hooked, curving backward. They have a preference for wet areas. Leaves are dark green, 1¼-2½" (3.2-6.3 cm) long, roughly oval with pointed tips, with finely serrated edges. They occur in odd pinnate groups, most commonly with 7 leaflets, sometimes with 5, rarely with 9. Flowers are 1½-2" (3.8-5.8 cm) in diameter, solitary (or in small clusters), light to dark pink, with five petals and strong rose fragrance. They appear from June to July. Fruits are red, less than ½" (1.3 cm) around.
