Mountain Spirea

Mountain spirea or subalpine spirea is a deciduous shrub native to high elevations of the Cascade Range and other western mountains, reaching 2-4 feet tall. It produces narrow leaves and dense clusters of bright pink to rose flowers appearing in mid- to late summer.

This species is extremely cold-hardy to zones 3-6 and thrives in full sun with well-drained soil and moderate moisture. It spreads via rhizomes and self-seeding and is useful for alpine gardens and high-elevation landscapes. The plant attracts butterflies and bees.
