Native to southern U.S., Mexico, and Guatemala; named varieties have a more compact or relaxed habit and bigger flowers than the 3-by-3-ft. species. Effective as fillers and spillers in containers and borders. Bright green leaves are divided into threadlike segments. Flower heads are bright golden yellow, with a light honey fragrance. There are many named varieties, from 7 to 24 in. tall and wide, in mounded, spreading, and trailing versions. A representative sampling is listed here.
‘Golden Eye’. Mounded, 10–12 in. tall and slightly wider.
‘Goldilocks Rocks’. Mounded, to 14 in. tall and wide.
‘Namid Compact Yellow’. Mounded, 7 in. tall and 16 in. wide.
