Coreopsis

Coreopsis tinctoria, often called plains coreopsis or tickseed, is a showy wildflower with bright yellow daisy-like flowerheads that have red centers. It is an upright, fast-growing annual. It is native to the south-central US and has naturalized in other areas. The flowers appear from summer into early autumn, and the bloom period runs from summer through frost.

Sowing. This plant is propagated by seed, and it can also be divided. The pages used for this draft do not give a sowing time or sowing depth. Choose a spot in full sun, where it gets 6 or more hours of direct sunlight a day. It grows best in fertile, well-drained soil. It prefers light, sandy soil but tolerates poor soil. It does best when crowded, so mass planting works well. Plants will self-seed into open, bare ground.

Watering. Water lightly and make sure the soil drains well, because it does not tolerate wet feet. Deadheading. Remove faded flowers to promote reblooming and to limit excessive self-seeding. Deadheading also prolongs the flower display.

No significant insect or disease problems are reported. The plant is generally pest-free and generally disease-free. It is resistant to deer browsing.

The flowers make a good cut flower.

This plant is listed as non-toxic to cats and dogs.
