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.

Useful in coastal restoration or retained along a coastal shoreline for stabilization. Salt marsh coastal stabilizer. Low dune stabilizer. Groundcover in coastal settings.

Three subspecies occur in Florida.  The subspecies ranges somewhat overlap.  Subspecies cruiseana is listed as Endangered by the State of Florida. Informal wildflower garden.

Bloom period can be prolonged by removing flowers as they wither. It does not compete well with aggressive plants. Wildflower garden. Blooms best in light shade. Use in a bog, pond or water garden.

The range includes all of peninsular Florida and the southern parts of Georgia, and Alabama. Best used as a wildflower as it has a relatively short lifespan.

Restoration proects and casual moist-site plantings.

The species is hermaphroditic (monecious), meaning flowers have both male and female reproductive structures on the same plant. This is a near-endemic meaning that it occurs mostly in Florida with a few outlying populations in Georgia and South Carolina. Moist wildflower gardens.
