Looking for a shrub that attracts butterflies and other nectar-feeding insects? Consider Spiraea tomentosa, also known as Steeplebush, Hardhack, or Meadowsweet. This vigorous plant can grow up to 4 ft high and prefers moist to wet soil and full sun. It blooms in the summer with narrow, pyramid-shaped clusters of tiny purple flowers. The plant also has a dense white-woolly tomentum which covers its stem and the underside of its leaves. Not only is this plant attractive to wildlife, but it is also noted for its medicinal properties, including astringent properties. It is hardy in Zones 4 to 6 and can be found natively in the northeastern United States and Canada. Try growing Spiraea tomentosa to add color, wildlife, and potential health benefits to your garden.
