Native to Mexico, Central America. Robust,
free-branching, nearly trouble-free plants ranging from 6
in. to 6 ft. tall, with flowers from pale yellow through
gold to orange and brownish maroon.
Finely divided, ferny, usually strongly scented leaves.
Annuals will bloom early summer to frost if old flowers are
picked off; in the desert, they bloom best from fall until
Handsome, long-lasting cut flowers; strong aroma from
leaves, stems, and flowers permeates a room (some odorless
varieties are available).
Easy to grow from seed, which sprouts in a few days in
warm soil; to get earlier bloom, start seeds in containers
indoors or buy nursery plants. Smog will damage tender young
plants, but they soon toughen up.
