Aster firmus (Shining Aster)
Aster firmus, or Shining Aster, is a pale white to lavender, late summer/early fall blooming Aster that is native to the wet prairies and damp soils of the eastern half of North America. It grows from three to four feet tall, thrives in full sun and moist soil, where it will spread if moisture level is adequate. I have no concrete information about zones, but this plant is native as far north as Canada and as far south as Georgia. Quarts.
