Eurybia divaricata (White wood aster)
Eurybia divaricata, the white wood aster, is a resilient native perennial aster well-suited to dry, shady sites. It typically reaches 1 to 2.5 feet with gracefully arching, dark purplish stems that carry delicate clusters of white, star-like flowers. Blooming profusely from late summer into fall, white wood aster brings light and life to understories when (and where) few other plants are flowering. The plant blooms earlier than many other asters, and rarely requires staking.
It typically occurs in nature nearby shady water sources such as the steep banks of rivers and streams, despite preferring mesic to dry conditions. It also occurs on rocky cliffs and is a common site in the Appalachians.
White wood aster's compact form and ability to naturalize make it an excellent groundcover choice for woodlands, forest edges, and under trees where many other plants may struggle. It spreads widely through rhizomes and reseeding in loose, sandy or loamy soils, to form a low growing colony in time. It struggles in dense, poorly draining clay soils.
White wood aster is a valuable late-season nectar source for native bees, butterflies, and other pollinators. Eurybia support specialist bees. It is also a host plant for the Pearl Crescent butterfly and other Lepidoptera species that rely on asters during their larval stages.
In addition to support for pollinators, Eurybia divaricata provides cover for wildlife and contributes to a woodland's biodiversity. Its adaptability to dry shade and ability to thrive in low-fertility soils make it a standout for ecological and low-maintenance landscaping.
