Symphyotrichum cordifolium (Blue Wood Aster) is a stout herbaceous perennial boasting branched, upright-arching stems topped by profuse clusters of daisy-like flowers in late summer and fall. Blooming for weeks, the flowers, usually less than 1 in. across (2.5 cm), feature golden-yellow centers surrounded by narrow rays ranging from dark blue to pale blue. Borne on smooth stems, their gentle color blends with almost any other color in the garden. The leaves are thin and sharply toothed, the lower leaves being heart-shaped (cordate) and the upper leaves being ovate to lanceolate. Tough and adaptable, Blue Wood Aster is an excellent choice for the mixed border where it makes a beautiful foil for other late-season perennials.
