Flowering - July - September.

Habitat - Bottomland forests, streambanks.

Origin - Native to the U.S.

Other info. - This striking species is found in Missouri only in a few counties, mostly in the east-central part of the state. It is perhaps most striking when in bud, with the spreading outer involucral bracts and nearly white inner bract tips giving rise to a characteristic "starry" appearance. When open, the flowering heads attract numerous insects. Another name for this plant is Senecio suaveolens
