Late Boneset

Eupatorium serotinum

Also known as Late Thoroughwort, Late-Flowering Thoroughwort

Late boneset fills fields and roadsides with dense, flat-topped clusters of tiny white flowers from late summer through autumn. Its robust, hairy stems carry lance-shaped leaves with distinct coarse teeth, providing an essential late-season nectar source for native bees, wasps, and butterflies. Highly adaptable to poor or damp soils, this vigorous perennial plays a vital ecological role in supporting pollinators when few other native wildflowers remain in bloom.

Responsible observation
  • Finding Plants: Look for dense, flat-topped white flower clusters along moist field edges in late summer and autumn.
  • Pollinator Watching: Visit sunny patches on warm afternoons to observe native bees, butterflies, and wasps feeding on nectar.
  • Gardening Use: Plant in full sun or partial shade in moist soil for low-maintenance late-season pollinator support.
