Growing Boltonia: Easy Care for Late-Summer Blooms

Pronunciation: bol-TOH-nee-ah

Boltonia is a tough, North American native perennial that brings clouds of daisy-like flowers to the late-summer garden. Its airy habit and tolerance for a range of conditions make it a valuable addition to borders and naturalistic plantings.

Light and Soil Requirements

Plant in full sun; in hot southern climates, partial shade is acceptable. Boltonia adapts to both damp and dry soils once established, though it performs best with consistent moisture.

Support and Maintenance

Taller varieties may flop and benefit from staking or support from neighboring plants. To keep plants compact and encourage bushier growth, pinch back stems by one-third to one-half once or twice before the end of June (July in the South).

Rejuvenation

If a stand of Boltonia declines after a few years, lift the clumps in spring, amend the soil with compost or organic matter, and replant the vigorous divisions. This refreshes the planting and restores vigor.
