This subspecies has a broad distribution that extends west into Texas and north into northern New England.  It is found broadly but sporatically in Florida.  Our map shows where herbarium specimens have been submitted, but it should be appropriate to plant this plant almost anywhere in the northern 2/3 of the state.   To avoid inbreeding, do not plant this subspecies in a common garden with either the east- or west-coast dune sunflower. Beach-front gardens.  Wildflower gardens. Groundcover.
