Plant Information

Fine, feathery foliage is topped with 1” lemon yellow flowers June-August or September.
Grows 18” h&w.

Origin: About 80 species of annuals and perennials widely distributed throughout the Americas, especially in the prairies through to the southwestern USA and Mexico

Culture: Full sun and average soil. Very rich or heavily fertilized soil can cause the plants to become floppy and overgrown. Good drainage is necessary.

Maintenance: Coreopsis are quite low maintenance. They are drought tolerant once established but benefit from some moisture when in bloom over the dry summer months. Be careful not to over-water or let the plant sit in standing water and keep fertilizing to a minimum. Tall varieties will need to be staked.
Coreopsis plants benefit from deadheading during their summer bloom period to encourage additional flowering. Cut entire plant back in winter after the first frost.

Older plants have a tendency to decline in vigor. To regenerate, dig up plant and separate the new growth from the older plant. Replant the newer sections and discard

Additional qualities: Attracts bees, butterflies and birds. Deer resistant. Drought tolerant. Great cut flowers.

Pests and Diseases: Mildew and root rot are the most common diseases- avoid overwatering or planting in soggy areas. Protect against slugs as new growth emerges in the spring. Coreopsis beetle is a new pest in the Portland area. It is especially active when night temperatures are above 55ºF, leaving skeletonized leaves. The adult beetles are black with cream stripes. They are best controlled by hand picking them off the plants. The larval stages can be controlled with Bt if caught early enough.
