Coreopsis leavenworthii Leavenworth's Tickseed1

Edward F. Gilman, Jeffrey G. Norcini, and Teresa Howe2


Thirteen coreopsis species occur in Florida, eleven of which are widely considered native to Florida. Coreopsis tinctoria is native to the U.S but is considered non-native in Florida. Coreopsis basalis is considered native by some and non-native by others. The genus coreopsis is Florida's state wildflower.

Coreopsis leavenworthii (Figure 1) is found throughout Florida, and until recently was considered endemic. It is an annual to short-lived perennial. These colorful plants have pinnately to bipinnately compound leaves. In cultivation, this species has more foliage than what would normally be seen in the wild.

Flowers are bright yellow with a dark brown center. A very narrow orange "ring" around the brown disc flowers might even be noticed. These lovely flowers are held upright upon tall, leafless stems that enable the blooms to be beautifully incorporated into flower arrangements, although there is no information on how C. leaveworthii performs as a cut. The flowers are borne in capitula with small discs, and the ray florets have dentate tips. Flowers are 1 to 1-1/2 inches in diameter; flowering is from late spring in north Florida to any time in south Florida.

Use and Management

Coreopsis species are generally short-lived and may only last 3 to 4 seasons. Try using these plants as a border or edge. They are also excellent for naturalizing and will reseed themselves. The stalks become long and weak and tend to break in windy or rainy weather.

Coreopsis leavenworthii require a sunny position in the landscape. They prefer well-drained soils that are not too rich; rich soils and overwatering cause these plants to topple over. Keep the soil relatively moist and remove dead flowers immediately to prolong blooming. Place these plants 6 to 12 inches apart in the garden.

Seed is the most common method of propagation for coreopsis. Division can also be accomplished in the spring or fall.
