Coreopsis tinctoria Nutt.
Plains coreopsis, Golden tickseed, Goldenwave, Calliopsis
Asteraceae (Aster Family)
A slender, 1-2 ft. annual
with pinnately-compound foliage, tickseed is known for its small but abundant yellow flowers, painted maroon near the center. Numerous smooth, slightly angled branches bearing showy, daisy-like flower heads with yellow rays surrounding a reddish-purple central disk. The yellow petals are notch-tipped. Flower heads occur on long stalks from the multi-branching stems.
This prevailingly western annual
has escaped from cultivation in the East. It is widespread in the West and the South in disturbed areas, such as moist ditches. Because of its showiness, the flower is cultivated extensively, hence its common name.
