Boltonia Boltonia asteroides

Previously known as:

  • Boltonia asteroides var. glastifolia
Phonetic Spelling
bol-TO-nee-uh ass-ter-OY-dees
Description

Boltonia is a perennial in the daisy family typically found in roadside ditches or marshes and other wet sites.  Growing in wet sites may require staking due to the plant tending to flop.  On the other hand, planting in dry soils will result in shorter plants and less showy blooms. Cutting back the stems in the spring, before flowering, will give you a shorter plant that will require less support.  

The blooms of this plant typically have white petals with a dome-shaped yellow center disk.  Others may have pink-tinged, or violet rays.  It can bloom from late summer until frost.  

This plant will spread through creeping rhizomes.

Insects, Diseases and Other Plant Problems: Powdery mildew can be an issue.
