Accent or specimen wildflower in open, coastal uplands.
Ecological Restoration Notes:
An importance componant for beach dunes and coastal strand along the east coast. Improperly used on the west coast where it hybridizes with the endemic west coast dune sunflower (H. debilis subsp. vestitus).
Typically 1-2 feet in height. Spreading and becoming much broader than tall; plants will merge together and form large patches.
Eastern coast of peninsular Florida from Miami-Dade County north to southeastern Georgia; doubtfully native to the Monroe County Keys.
Open coastal uplands.
Moist, well-drained sandy soils, without humus.
Low; it grows in nutrient poor soils.
Salt Water Tolerance:
Low; does not tolerate long-term flooding by salt or brackish water.
Salt Wind Tolerance:
Frontline; grows in direct salt wind but away from constant salt spray.
High; does not require any supplemental water once established.
Yellow, with dark centers.
Inconspicuous achene. All year.
Wildlife and Ecology:
An important sand binder on beach dunes.
Can be grown from seed. Once established it is self seeding.
Can become ratty-looking after peak flowering. Plants may need to be trimmed back heavily and allowed to re-sprout or recruit from seed.
