Douglas’ spiraea is an elegant, fast-growing, deciduous shrub with showy pink flower clusters and an easy-going nature. Inhabiting moist forests, streambanks, ponds, wetlands, seeps and springs at low to high elevations, Douglas’ spiraea is a go-to plant for riparian habitat restoration, erosion control, moist pollinator gardens, and hedgerows. Douglas’ spiraea is an upright or arching, suckering or clump-forming shrub that grows 5′-7′ tall. Plant in a location where it can happily spread and turn into a patch or thicket. Also known by the common names rose spiraea or hardhack. Tolerant of full sun to part shade, but will flower more in full sun. The showy, hot-pink or rose pink flower clusters are arranged in a spire-like, pointed cluster. Blooms July to August. Attractive to hummingbirds, bees, butterflies, and other pollinators. Douglas’ spiraea is native to the western United states and is a member of the rose (Roseaceae) family.
