Culture
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.
Reseeding will not occur.
Noteworthy 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.
‘Crème Brulee’ is a yellow-flowered coreopsis (tickseed) that is being promoted as an improved version of C. verticillata ‘Moonbeam’. It was discovered as a naturally occurring whole plant mutation of ‘Moonbeam’, and reportedly is distinguished therefrom by having deeper yellow flowers on larger inflorescences on a more vigorous plant clad with brighter green leaves displaying better resistance to powdery mildew. This is a threadleaf-type that typically grows in dense, bushy clumps to 12-20” tall eventually spreading to 35” wide. Butter-yellow daisy-like flowers (to 1” diameter) with toothed rays and darker yellow center disks bloom profusely from June to October. Lacy deep 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 PP16,096 was issued November 8, 2005.
Problems
Crown rot may occur if grown in moist, poorly drained soils. Uncommon diseases include botrytis, aster yellows, powdery mildew and fungal spots. Plant stems tend to sprawl, particularly in hot and humid climates with periodic heavy summer rainfall. Deer tend to avoid this plant.
Foliage reportedly has good resistance to powdery mildew.
Uses
Border fronts. Sidewalk edgings. Also effective in naturalized areas, wild gardens or cottage gardens. Good plant for areas with poor, dry soils. Patio containers.
