Fact Sheet

Uses

This plant is used mainly for landscape beautification, Use soil moisture sensors to measure the soil moisture of Coreopsis crassifolia Aiton., It has potential for use in cultivated, garden situations, in naturalized prairie or meadow plantings, and along roadsides,

Status

Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values).

Description

This plant is a clump-forming perennial herb with short rhizomes. Leaves may or may not be hairy; basal leaves are divided and the upper leaves are entire and oval-shaped. The flower heads are borne singularly or in small groups on upright stems from April to June. They are 1-2 inches in diameter and yellow with a yellow center. The seed are dark brown, winged, and curved to almost semi-circular.

Adaptation and Distribution

Distribution

Distribution

Lance-leaf coreopsis prefers full sun, but will tolerate light shade. On sites that are heavily shaded, plants produce fewer flowers and the stems grow taller. It can grow on many soil types, but prefers a well-drained soil. Natural stands are often found on dry, infertile sites. Lance-leaf is distributed throughout the eastern and midwestern United States. For a current distribution map, please consult the Plant Profile page for this species on the PLANTS Website.

Establishment

A firm seedbed is required. Seed may be planted into a closely mowed, chemically-killed, or burned sod area with a light disking or harrowing that scratches the soil surface. When seed is sown onto a clean-tilled site, culti-packing the soil before planting is recommended. A thick layer of plant residue on the soil surface may interfere with seed germination. Broadcast or shallowly drill 5-7 grams of seed per 100 square feet (5-7 lb/acre). Planting depth should range from at the soil surface to one-eighth inch deep. Cultipacking after planting is recommended. Seed germination should occur by fall, and the plants will remain as a low-growing rosette throughout the winter.
