An upright clumping perennial wildflower.  The attractive leaves are bright green thick and glossy.  In autumn lovely clouds of golden daisies attract drifts of migrating butterflies.  This late blooming sunflower extends the season of yellow flowers until frost.  Plants reach a stately 6’ or taller in sunny or partly sunny moist sites.

Habitats include floodplains, open bottomland forests, swamps, bogs, wet meadows, savannas, coastal salt marshes, wet flatwoods, pine barrens, roadsides, ditches and disturbed wet areas.

Plants are hardy from USDA Zones 5-9.  Flowering begins in September or October and continues until frost.  The starry daisies are particularly striking against the intense blue October sky.

Golden brown seed clusters follow and remain into winter to feed the birds.

Plants grow 5-7’ and up to 10’ tall with 4-6’ or greater spread.
