General Culture:

Easily grown in dry to medium wet, 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 in optimum growing conditions will naturalize to form large colonies. Plants may be cut back hard in summer if foliage sprawls or becomes unkempt. If grown in borders, division may be needed every 2-3 years to maintain robustness.

Noteworthy Characteristics:

Lanceleaf coreopsis is a Missouri native wildflower which typically grows to 2 tall and occurs in prairies, glades, fields and roadsides primarily in the Ozark region of the State. Features solitary, yellow, daisy-like flowers (1-2" diameter) with eight yellow rays (toothed at the tips) and flat yellow center disks. Flowers bloom atop slender, erect stems from spring to early summer. Narrow, hairy, lance-shaped leaves (2-6" long) appear primarily near the base of the plant in basal tufts. Lower basal leaves are mostly entire, while smaller stem leaves may be pinnately lobed. Plants in the genus Coreopsis are sometimes commonly called lanceleaf tickseed in reference to the resemblance of the seeds to ticks. Many excellent cultivars of this species are available in commerce.

Problems:

No serious insect or disease problems. Can be an invasive self-seeder. Tends to sprawl, particularly if grown in moist and/or fertile soils. Crown rot may occur if grown in moist, poorly drained soils.

Uses:

Best naturalized in native wildflower gardens, meadows or prairies. Good plant for areas with poor, dry soils. Can be effective in borders, but self-seeding tendencies must be kept in check.
