Spiraea douglasii

This fast-growing deciduous shrub exhibits an upright and bushy habit, reaching a mature height of 4 to 6 feet with a spread of 3 to 5 feet. It thrives in USDA hardiness zones 5 to 7, preferring cooler temperate climates, and tolerates temperatures down to -20°F. The narrow leaves display a deep green color during the growing season, turning to yellow or golden hues in autumn for added seasonal interest. Summer brings clusters of pink to purplish flowers that bloom on tall spikes, attracting pollinators such as bees and butterflies. Its fruit consists of small, inconspicuous seed capsules that provide subtle long-term interest. Spiraea prefers moist but well-drained soils and performs well in sun to partial shade conditions. With its upright, vase-like form, this plant is ideal for naturalistic borders or erosion control near water features. Additionally, it offers moderate resistance to deer, making it a dependable choice for wildlife gardens.
