Spiraea tomentosa L.
Rosaceae (Rose Family)
Synonym(s): Spiraea tomentosa var. rosea, Spiraea tomentosa var. tomentosa
USDA Symbol: SPTO2
This mound-shaped, deciduous shrub forms a thicket of erect, slender, wand-like, unbranched stems, 3-6 ft. tall. Dense, erect, plumes of pink to rose-purple flowers occur terminally. The orange to reddish-brown bark is exfoliating and the fall foliage is yellow. An erect shrub with dense, steeple-shaped, branched clusters of pink flowers.
A similar species, the pink-flowered Japanese Spiraea (S. japonica) from Asia, differs from Steeplebush in having flat-topped clusters of flowers and smooth leaves; since its introduction into North America, it has invaded a broad area, from Ontario and Michigan east to Maine and south to Georgia, Tennessee, and Illinois.
