Rose

You'll recognize this deciduous shrub by its distinctive deep pink flowers clustered in tall, pyramidal panicles appearing powdery from countless projecting stamens. Native to the Pacific Northwest from Oregon to Alaska, Spiraea douglasii typically grows 4 to 7 feet tall with an erect, compact form. The alternate leaves are oblong, dark green and smooth above, whitish and felty underneath. Often found growing naturally in wet places like marsh borders and stream banks, it forms dense colonies by slowly spreading through rhizomes. The flower clusters mature to persistent brown seed heads that add winter interest.

In Western Washington gardens, you'll find this shrub performs best with full sun and low moisture once established, though it does well in wet soils where many plants struggle. Hardy through zones 4b to 8b, it tolerates a wide range of soil pH from 5.5 to 7.5 and actually prefers consistently moist conditions. Summer blooming occurs on new wood (June to August), so prune after flowering ends. Watch for susceptibility to powdery mildew, rust, and a variety of pests including spider mites, roseslugs, and aphids. Deer readily browse the foliage. Use this species in hedges or rain gardens where you want a low-maintenance native shrub.
