False Aster

Boltonia asteroides

False Aster delights with tall, slender stems topped with countless tiny, starry, white flowers from late summer into fall, creating a misty effect in the landscape. This robust perennial can reach impressive heights and spreads to form large clumps, making it ideal for the back of a border or as a naturalistic screen. Its vigorous growth and abundant flowering make it a magnet for butterflies and other pollinators, providing vital late-season nectar.

Maintenance Tips

  • Cut back in mid-spring to encourage bushier growth and prevent flopping, or stake plants in windy areas.
  • Prefers moist, well-drained soil, but is adaptable to various soil types.
  • Divide every 3-4 years in early spring to maintain health and control spread.
  • Manage self-seeding by deadheading before seeds fully mature if unchecked growth is not desired.
