Many coreopsis are native to Illinois and other praries states. I live in Illinois, and it seems to thrive in its natural area here. It produces stems from which skinny, smaller stems protrude. These hold the beautiful, bright yellow, daisylike flowers. Rabbits seem to find mine a real delicacy; try rabbit and deer prevention spray for this problem. It works for me.

The lanceleaf coreopsis is a favorite of the goldfinches who visit my yard. They will hang on a seed pod until they scarf down every last seed. It is a lovely addition to those that do not care if a bird shares the harvest.

my sister sent me a packet of seeds. I planted about 6 mos. ago and plants seem healthy but have not yet bloomed. Can somebody tell me when I should expect plants from seed to bloom? Don't know how they'll do here in zone 11, packet did not list zones, but does say they are drought tolerant whem mature. My plants are about 8"-10" tall. If they bloom will change rating to positive and add to list of where they grow.

Cheerful, easy plant. Flowers face east in the morning and west in the afternoon, but sometime after dark --they turn east again, as if anticipating the sun. I love the idea that it doesn't just lean to the sun, it knows where the sun comes up and prepares for sunrise.

A native American plant. Surely not an unusual plant or with outstandingly showy flowers, but grown extensively for good reason. Blooms over a long period, and it is VERY easy to grow, thriving in a variety of conditions, its only demands are probably to be planted in full sun, and not to be planted in the wettest or heavy clay spots. Bright yellow flowers are cheery, combine well with many flowers and are a good addition to most gardens. Its somewhat open and airy habit can add a softening effect when planted around stiffer plants. Very easy to grow from seed, should deadhead or remove seedheads, if self-sown seedlings are not desired. Not bothered by diseases or insects. However, after a strong rain, in partial shade or overly rich or wet soil, plants can tend to flop over. Plants are so easy to grow that they can spread almost invasively. Monitor their growth, but their spreading is seldom a nuisance.

Makes great cut flowers, lasting over a week. Grew very tall (3 1/2 ft) and flowered, I cut it back after it started to slow on flower production and it burst forth with tons more blooms. I keep it dead headed, produces tons of seed.

These are a perennial in zones 4-9. They need full sun and well drained soil that is fertile and somewhat moist. They produce 1 1/2 to 2 1/2" flowers that are yellow. They will have single to double flowers on top of 12-12" stems. The foliage is a deep green. They bloom from summer to fall.
