Tansy-aster is a cheerful native wildflower producing bright violet-purple daisy-like blooms that attract pollinators throughout summer and fall. It prefers full sun and well-drained soils, tolerating dry conditions well once established with minimal supplemental watering. A great choice for meadow gardens, roadsides, or naturalized borders with very little required maintenance.
