Fall Aster
Symphyotrichum oblongifolium
Native aromatic aster that explodes in lavender-blue fall blooms when butterflies need nectar most. Tough as nails on limestone and summer drought.
Landscape use
Fall pollinator gardens, native borders, meadow edges, and rock gardens.
Care
Full sun. Pinch or shear by early summer for denser fall bloom. Low water. Cut back in winter. Spreads politely by rhizomes.
