Flowering late summer–fall. Sand hills; 10–100 m; Ala., Ga., N.C., S.C.
Pityopsis pinifolia is known from a few scattered sandy locations near the coast in South Carolina as well as on fall-line sand hills. It is known to hybridize with P. aspera var. adenolepis in Moore County, North Carolina. Although it is sometimes locally common, overall it is very uncommon and considered threatened in Georgia and Alabama. The report from Mississippi has not been confirmed. It was reported as ephemeral in New York. The species has also been called the Taylor County goldenaster, referring to one of its locations in Georgia.
