General Culture:
Easily grown in medium moisture, well-drained soil in full sun. Plants tolerate humidity and some dry conditions, but are not as drought tolerant as some other species of Coreopsis. Prompt deadheading of spent flower stalks can be tedious for a large planting, but does tend to encourage additional bloom. Plants may be sheared in mid summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. In optimum growing conditions, this rhizomatous perennial will slowly spread in the garden over time to form an attractive planting, but spread is easy to check and is not invasive. Clumps may be divided in spring. 慫amfir?reportedly may be grown from seed.
Noteworthy Characteristics:
慫amphir?is a compact but slightly larger version of C. ariculata 慛ana?(see N770). It grows in a dense, bushy, slowly spreading clump to 12-18?tall. It is distinguished from other forms of coreopsis by the uniquely fluted orange-yellow petals on its 2-inch diameter daisy-like flowers. Petals may flatten with age. Primary bloom is from late spring to early summer. Sparse and intermittent rebloom may continue throughout the summer into fall if spent flowers are regularly deadheaded, however in hot summer climates like the St. Louis area plants often stop blooming in mid-summer with a rebloom occurring in fall after temperatures moderate. Broad-oval, shiny, deep green leaves. Ariculata means 揺ared?in reference to the ear-like lobes at the base of some leaves. Plants in the genus Coreopsis are sometimes commonly called tickseed in reference to the resemblance of the seeds to ticks.
Problems:
No serious insect or disease problems. Tends to sprawl if grown in moist and/or fertile soils. Crown rot may occur if grown in moist, poorly drained soils. Foliage decline in hot summer climates may occur if soils are allowed to dry out.
Uses:
Bright flowers and long bloom provide excellent accent in borders or meadows. Best in groups or massed. Also effective as an edger for walks/paths.
