Aster oblongifolius, commonly known as Aromatic Aster and botanically classified as Symphyotrichum oblongifolium, is a native perennial wildflower found across much of the central and eastern United States. This compact, mound-forming aster typically grows 1 to 3 feet tall and wide and is known for its aromatic foliage, which releases a pleasant scent when crushed. Blooming in late summer through fall, Aromatic Aster produces masses of violet-blue, daisy-like flowers with yellow centers, creating a dense display of color late in the season. It thrives in full sun and well-drained soils and is especially tolerant of heat and drought once established.
