Boltonia asteroides (False Aster)

Boltonia, White Doll's Daisy, False Chamomile, False Aster, Thousand-Flowered Aster


Forming a mound of radiant color in the late season garden, Boltonia asteroides (False Aster) is a rhizomatous perennial boasting masses of tiny, daisy-like flowers in midsummer to early fall. Borne in broad clusters, the flowers, 3/4 in. (2 cm), feature white to pink, purple, or blue rays surrounding a dome-shaped, yellow central disk. Flowering is so flat profuse that the blossoms literally cover the plant. The flowers are borne on sturdy, branching stems clothed with a beautiful foliage of alternate, lance-shaped, blue-green leaves, 5 in. long (12 cm). Spectacular when in bloom, False Aster is easy to grow, brings cheerful fall color and is a great source of nectar for butterflies. Perfect for the middle or back of the border, prairies or naturalized areas.

  • Grows up to 5-6 ft. tall (150-180 cm) and 2-4 ft. wide (60-120 cm). Slowly spreads by creeping rhizomes.
  • Thrives in full sun in average, medium moisture, well-drained soils. Tolerates a wide range of soils, including clay soils. Provide good air circulation to avoid foliage diseases such as powdery mildew.
  • Great for adding white color to late season beds and borders, cottage gardens, prairies and meadows or butterfly gardens. Valued for the quality of its cut flowers.
  • No serious pest or disease issues. Keep an eye out for powdery mildew.
  • Pinch or cut back stems in late spring to early summer to promote bushiness and control the plant height (to avoid flopping).
  • Propagate by seed or root division.
  • Native to eastern North America.
