Symphyotrichum subspicatum
Symphyotrichum subspicatum
Douglas's aster is a resilient native perennial that thrives in partial shade with consistent moisture, making it ideal for woodland garden edges and naturalized areas. Plant it in well-draining soil and water regularly during dry spells, especially in its first season while establishing. Once settled, it requires minimal care and rewards you with a late-season flush of lavender-blue daisy-like flowers beloved by pollinators.
