Decurrent False Aster
Decurrent false aster is a perennial plant that occasionally reaches heights of over 6 feet. It blooms from July to October and bears seeds from August to October. Leaves are linear and narrow and have a blue tint. The lower leaves are broader and larger.
This plant is called "decurrent" because the leaf tissue extends down the stem from the point of leaf attachment. The flowers are about the size of a quarter. They occur in branched groups of composite heads with yellow disk flowers and white to purplish or pinkish ray flowers.
Decurrent false aster is closely related to Boltonia asteroides var. recognita, which is a common weedy species of false aster. It is sometimes found in the same habitat with decurrent false aster; however, it lacks decurrent leaves.
