Swamp rose, rosa palustris, is a 3-6 foot shrub that grows best in slightly acidic, wet to moist soils in full sun, though will tolerate light shade and seasonal flooding. Pink flowers are extremely fragrant, lasting 6-8 weeks (June-July). The fruit (rose hip) is red and fleshy with a mass of seeds inside, which are eaten and spread by birds. Not susceptible to insects and pests that attack hybrid roses. Host to the blinded sphinx moth.
