Description
Narrowleaf meadowsweet shrubs often reach 8 feet in height with a spread of 3–4 feet. This species is often the most conspicuous part of the vegetation in its habitat, taking up large areas of ground. Its leaves are glossy yellow-green, oblong or lance-shaped, and toothed on the edges, and its twigs are tough and yellowish brown. Fall foliage is golden yellow. The white and sometimes pink fragrant flowers grow in spike-like clusters at the ends of the branches, blooming from early summer through September. The brown fruit, which persists after flowering, is a distinctive feature of all ''Spiraea'' species.
Ecology
Butterflies and other beneficial insects visit the plant for nectar and pollen. In autumn brown seed capsules appear and are fed on by songbirds. Glossy green foliage turns yellow in the fall. Deer tend to leave this plant alone. Meadowsweet is a host plant for the larvae of the spring azure butterfly (''Celastrina argiolus'').
Uses
The blooms make a good cut flower.
The hollow, upright stems were used historically as pipe stems.
