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.
