Large-Leaved Aster (Big-Leaved Aster)
Eurybia macrophylla [C-value 9]
Aster family (Asteraceae)
Blooms September - mid-October

The native Large-Leaved Aster is uncommon in our area. It prefers partial sun to medium shade and moist to slightly dry rich soil. Habitats include sandy oak woodlands, sandy oak savannas and woodland borders. This perennial has a rosette of basal leaves during the spring that spans about 6-12" across. In the summer, sparingly branched stems develop with alternate leaves up to 4" long and 3" across on winged petioles up to 3" long. The upper stems terminate in a panicle of flowers 3-8" across. Individual flowers are ½-1¼" across, with 8-20 lavender to white ray florets surrounding numerous yellow or purple disk florets.
