Found in field behind my apartment in Myrtle Beach, SC / USA
The Late Purple Aster blooms mostly from September through October, and you are most likely to find it along sunny roadsides or in fields. The flower heads are about 1" across and contain roughly 15 “petals” (technically they are called ray flowers). The color is a deep violet and the central “disc” flowers are usually a bright yellow. If you look at these flowers near dusk, the brightly contrasting discs appear to glow in the dim light. The stems are sparsely hairy, and the leaves are oblong, toothless and clasp the stem. Surrounding the outside base of each flower are many tiny green bracts (leaflike structures) with spreading tips.
