| Distribution | Outer Banks, other barrier islands, and several maritime sites on the mainland. Inland records are of garden escapes or adventive plants. Note that many references consider the species as adventive as far east as the Carolinas; a paper by Franck supporting this was published in JBRIT (vol 14: 205-208). Weakley's (2020) map also shows it as not native in any Southeastern state east of LA. First collected in 1923 in New Hanover County ("established at the beach").
Coastal Plain, NC to FL and TX (var. drummondii). Other varieties occur northwestward through prairies and southwestward through deserts to AZ. | |
| Abundance | Common to locally abundant along the immediate coast. Scarce farther inland near inner portions of sounds (Pamlico Sound). | |
| Habitat | Dry maritime grasslands, stable dunes, interdune swales, roadsides, yards, and sandy vacant lots. | |
| Phenology | Flowering and fruiting mostly May-August (sometimes later). | |
| Identification | This is a very familiar coastal plant, easily spotted when in bloom. The large heads with bicolored red and yellow rays and deep brownish purple disks, are diagnostic. Plants spread low to the ground; sometimes stems will be rather erect. It certainly has some weedy tendencies, and some sites in coastal regions could perhaps be plantings. | |
| Taxonomic Comments | Our plants are recognized by Weakley (2018) as variety drummondii, but FNA lumps it.
