Culture

Easily grown in dry to medium moisture, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Tolerant of heat, humidity and drought. Prompt deadheading of spent flower stalks encourages additional bloom and prevents any unwanted self-seeding. Freely self seeds and can become somewhat weedy. Also spreads by rhizomes. Plants are somewhat short-lived and self-seeding helps perpetuate a good planting in the garden. Plants may be cut back hard in summer if foliage sprawls or becomes unkempt. When grown in borders or other formal garden areas, division may be needed every 2-3 years to maintain robustness. May be grown as annuals.

'Early Sunrise' generally comes true from seed.

Noteworthy Characteristics

Coreopsis grandiflora, commonly called large-flowered tickseed, is native to prairies, glades, open woods, thickets, roadsides and open ground in the southeastern U.S. from Florida to Texas and New Mexico north to Georgia, Missouri and Kansas. It typically grows in a clump to 2' tall. Daisy-like single flowers (2-3" diameter) feature deep yellow rays (notched at the tips) surrounding a darker golden yellow center disk. Flowers appear singly atop slender, erect stems rising to 2' tall. Flowers typically bloom from late spring to late summer and sometimes into fall, though bloom period can be much shorter if spent flowers are not regularly deadheaded. Upper leaves are pinnatifid and deeply lobed, but lower leaves at the base of the plant are lobeless and linear. Through introduction and garden escapes, this coreopsis has become established in the eastern and central U.S. well north of its native range.

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.

Specific epithet means large-flowered.

Common name of tickseed is in reference to the resemblance of the seeds to ticks.

'Early Sunrise' is a compact cultivar which features solitary, yellow, daisy-like, semi-double flowers (to 2" diameter) with yellow rays and darker yellow center disks atop slender, erect stems rising to 18" tall. Flowers typically bloom from late spring to late summer and sometimes well into fall, though bloom period can be much shorter if spent flowers are not regularly deadheaded. Spatulate to lanceolate leaves. Lower basal leaves are mostly entire, while smaller stem leaves are often pinnately lobed. 1989 All-America winner.
