From WSU Clark County Extension:
Nootka Rose is a fast-growing, deciduous, erect shrub that can attain a height of 6’ with an equal spread. New plants arise from the mother plant via underground runners. Leaves are pinnately compound, with five to nine ovate and serrated leaflets. At the base of the leaves is a pair of thorns. Leaflets are arranged in an alternate fashion. Flowers appear from May through July. They are pink, about 2” across and subtle but sweet smelling. Each flower has five petals and five sepals. Stems have varying numbers of thorns. Flowers give rise to red fruit known as hips and are large (½” - ¾” long) and round.
Nootka Rose grows in both full sun and partial shade. It can tolerate flooding and can grow well on a host of different soil types. Summer drought does not have a real effect on this species.
