Description

Lanceleaf Coreopsis (Coreopsis lanceolate) is a native wildflower which typically grows to 2 feet tall and occurs in prairies, glades, fields and roadsides. Features solitary, yellow, daisy-like flowers (1-2 inchesdiameter) 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 inches 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.

The blooming period occurs from late spring to mid-summer, lasting about 1 month for a colony of plants. Afterwards, the disk florets are replaced by achenes that are about 3 mm. long, 3 mm. across (including the membranous wings), brown, and flattened (slightly convex on one side and slightly concave on the other side). The tips of these achenes soon become truncate because their paired awns are early-deciduous. The root system is fibrous and rhizomatous, often forming colonies of clonal plants.

Habitats include mesic to dry sand prairies, gravel prairies, hill prairies, limestone glades, thinly wooded bluffs, areas along railroads, and roadsides. Some local populations may be plants that have escaped cultivation. In addition, some populations within the state are the result of habitat restoration efforts.

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 in optimum growing conditions will naturalize to form large colonies. Plants may be cut back hard in summer if foliage sprawls or becomes unkempt.

Plant Notes and Herbal Uses
