Symphyotrichum cordifolium (Blue Wood Aster)

Blue Wood Aster, Heart-Leaf Aster, Aster cordifolius


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, 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.

  • Grows with a bushy habit, up to 2-5 ft. tall (60-150 cm) and 2 ft. wide (60 cm). May need staking
  • Thrives in full sun to part shade in moderately fertile, dry to moist, well-drained soils. Prefers moist, rich soils, but avoid consistent moisture. Rabbit and deer resistant!
  • Vital ingredient of late summer and fall borders, cottage gardens, prairies or butterfly gardens. Asters are also valued for the excellent quality of their cut flowers.
  • Asters are a great source of nectar for butterflies and are a must if you are trying to attract birds or butterflies!
  • Propagate by division in spring. Cut back in late fall.
  • Generally pest free. May suffer Verticillium wilt, powdery mildews and grey moulds
  • Native to eastern and central North America.
