Coreopsis, Lanceleaf

Herbaceous Perennial Flower, Wildflower

Also known as Lanceleaf tickseed
Coreopsis lanceolata
Asteraceae Family

Very similar to Large-flowered Coreopsis (C. grandiflora), with showy, large (up to 2.5-inch) golden-yellow blooms and attractive medium-green foliage. Doesn't produce quite as many flowers, but is longer-lived and has leaves mostly just at the base of the plant.

Growing Information
How to plant:

Propagate by seed, cuttings, division or separation - Divide every 2 to 3 years in early spring to promote cold hardiness and maintain plant vigor. Undivided plants are not long-lived.

Sow seeds indoors in late winter, or outdoors in seedbed in midspring. Move to garden when frost danger has passed.

Make cuttings in spring.

Maintenance and care:
Plants are short-lived, but don't flower themselves to death as fast as large-flowered tickseed (C. grandiflora). To maintain hardiness and vigor, divide every 2 to 3 years.

Deadhead daily to prolong blooming. Cut plants back in midsummer if their growth becomes straggly. This prevents excessive flowering, which can kill the plant.

Cut plants back nearly to the ground in late summer or early fall to encourage healthy new foliar growth. Allow foliage to remain for the winter, then clean up the plants in the spring.
