Plains Coreopsis (Coreopsis tinctoria)
Flowers
Stalked flowers are single or in a cluster of a few flowers at the top of the stem and at branch tips. Flowers are 1 to 2 inches across with 6 to 12 rays (petals), usually 8, that are typically bright yellow at the tip and maroon at the base, occasionally all yellow.
Fruits/Blossoms
Fruit is a dark brown to black, oblong-elliptic seed up to 1/6 inch (to 4 mm) long, lacking a tuft of hairs
Leaves
Leaves are opposite, 2 to 6 inches long, to 4 inches wide, stalkless or short-stalked, and divided into 3 to 5 narrow segments, the lower leaves commonly further divided. Stems are hairless, usually branched, single or multiple from the base.
Habitat
Full sun and well drained soil are best. Grows naturally in glades and sandy soil, often in disturbed ground.
Fun Fact!
The common name of tickseed is in reference to the shape and appearance of the seed. Don’t worry – this plant doesn’t attract ticks!
****Not only will these sunny flowers add color and beauty to the landscape, they will also attract bees and butterflies. Once you identify a Plains Coreopsis, look around and see if you can observe any bees or butterflies nearby.
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.
