Tickseed (Coreopsis ‘Autumn Blush’)

Tickseed

Features and Characteristics

Coreopsis is a genus of between 75-80 species from North America, Mexico, Central and South America.

The genus name comes from the Greek words koris meaning “bug” and opsis meaning “like” in reference to the shape of the seed which resembles a bug or tick.

‘Autumn Blush’ is a hybrid perennial coreopsis that blooms like an annual from spring to fall, featuring large flowers that change color with the seasons. It typically grows in a mound to as much as 26” tall and 32” wide. In summer, each daisy-like flower (to 2” diameter) features bright peachy-yellow rays surrounding a red center. During the cooler weather of spring and fall, the ray flowers display a reddish blush. Flowers appear, often in profusion, over a mound of narrow, linear, green leaves. Plants in the genus Coreopsis are sometimes commonly called tickseed in reference to the resemblance of the seeds to ticks. U.S. Plant Patent Applied For (PPAF).

Care and Maintenance

Easily grown in dry to medium moisture, well-drained soils in full sun. Tolerant of heat, humidity and some drought. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. Plants may spread by rhizomes. Clumps may be divided in spring. When grown in borders or other formal garden areas, division may be needed every 2-3 years to maintain robustness.

Hardiness and longevity of hybrid coreopsis depends greatly on parentage, and ranges from hardy, fully perennial selections to half-hardy or tender perennials more often grown as annuals.

‘Autumn Blush’ is reportedly sterile, so self-seeding is not a problem.
