Discussion

Coreopsis tinctoria is widely grown in public and residential gardens, and commercially (for cut flowers), and has become widely established in the flora area.

As here circumscribed, Coreopsis tinctoria includes plants that others (without agreement among themselves) have treated as distinct species or infraspecific taxa: C. atkinsoniana (plants mostly 50–150+ cm, seldom branched from bases; cypselae 2.5–3 mm, “narrowly” winged; pappi 0.1–0.2 mm; mostly Idaho, Montana, Oregon, Washington), C. cardaminefolia (plants mostly 20–50 cm, seldom branched at bases; cypselae 2 mm, “narrowly to widely” winged; pappi 0 or 0.1–0.2 mm; mostly Arkansas, Kansas, Louisiana, Nebraska, Oklahoma, Texas), and C. tinctoria var. similis (plants mostly 10–30 cm, usually branched from bases; cypselae 2–3 mm, “widely” winged; pappi 0.2–1 mm; Texas and Mexico).
