Blue spirea is a low, mounding, deciduous shrub in the Lamiaceae (mint) family. It is a hybrid cross between C. incana and C. mongholica. The common name blue mist refers to the flowers which have a fluffy cloudlike appearance.
This light airy shrub quickly reaches an average size 2 to 3 feet tall and wide and has a medium to fine texture. When there is little else blooming in the garden in the late summer and early fall this plant will delight with its bright blue fragrant flowers that attract butterflies, bees, and other pollinators. In cold climates below zone 6 the stems will die back to the ground.
Plant in loose, well-drained loamy soil in the full sun. Too much fertilizer will result in lanky growth. Cut it back in late winter to improve its form and remove dead stems as the blooms appear on new growth. It is very easy to transplant, tolerant of drought, is pest and disease resistant, and is seldom browsed by deer.
Plant this shrub in groups or mass planting along shrub borders or use as a low growing hedge. Its fragrant foliage and nectar-rich flowers make it a wonderful addition to a cutting, sensory, or pollinator themed garden.
Quick ID Hints:
