Winged False Aster Boltonia decurrens

Previously known as:

  • Boltonia asteroides var. decurrens
  • Boltonia latisquama var. decurrens
Description

Decurrent False Aster is an herbaceous perennial, a species of flowering plant native to a small area of Illinois and Missouri and is protected under the Endangered Species act. It grows along floodplains and wetlands and in moist bottomlands of the Illinois and Mississippi Rivers. Although native to those area only, seeds may be obtained by gardeners in other areas of the country. The plant requires periodic flooding, but not continued standing water and can grow quite tall, requiring staking or other support.

Decurrent False Aster typically forms a clump 4  to 6 feet tall on erect branching stems. Pale pink or purple-tinged to white daisy-like flowers (to 1” diameter) cover this aster-like plant with a profuse bloom in August and September. Each flower has pale pink to white rays with a yellow center disk.

Decurrent False Aster prefers full sun, wet to moist conditions, and fertile soil containing loam, clay-loam, or silty deposits. The plant can tolerate drier conditions in gardens if it is watered during dry spells. The plant will grow best if cut back by a third in the Spring.

Diseases, Insects, and Other Plant Problems: May require support when tall. Powdery mildew may be a problem.
