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 or wet soils. Growing in wet sites may require staking due to the plant tending to flop. 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.
