Uses

This plant is used mainly for landscape beautification. It has potential for use in cultivated, garden situations, in naturalized prairie or meadow plantings, and along roadsides.

Description

Coreopsis tinctoria is an annual forb which usually germinates in late summer or fall and overwinters as a rosette (round, low growing group of leaves). The stems begin growing upward and branching in spring, reaching a height of up to 4 feet. The opposite leaves are deeply divided, with the upper leaf segments being very narrow. The flowering heads are numerous, 1-2 inches in diameter, and are yellow with a red-brown center.


Adaptation

Coreopsis tinctoria is adapted to many soil types. It grows best on a well-drained soil, but will not tolerate a very dry site. Natural stands are generally found on bottomland areas with ample moisture. It grows best in full sun, but will tolerate light shade.

Coreopsis tinctoria is distributed throughout the majority of the United States.

Establishment

A firm seedbed is required. Coreopsis tinctoria germinates best on a clean tilled site that has been firmed with a roller or finishing harrow before planting. Seed can also be planted into a closely mowed, chemically-killed, or burned sod area with a light disking or harrowing that scratches the soil surface. A layer of plant residue on the soil surface can interfere with seed germination. Broadcast or shallowly drill 1-2 grams per 100 square feet (1-2 lb/acre). Seed should be placed close to the soil surface. Cultipacking after planting will ensure good seed to soil contact. Seed will germinate soon after planting and remain as a rosette throughout the winter.

Management

Plant growth and seed production are greatly improved by fertilization. Apply fertilizer according to soil test recommendations. If not available, a rate of 3.5-5.5 oz per 100 square feet (100-150 lb/acre) of 13-13-13 should be applied in the spring before flowering. Stands will reseed prolifically for several years, but will gradually decline without soil disturbance. Every two to three years, the site should be disked to control perennial weeds and promote calliopsis germination. If necessary, plants can be mowed in the spring before stem elongation begins. Stands that are not disked should be mowed in late summer, and a late fall mowing is also recommended.

Direct sow in late fall, planting the seed on surface of the soil and compacting it firmly. The seeds will germinate soon and overwinter as a small cluster of leaves, sending up a flowering stalk in the summer. For spring planting, mix the seed with moist sand and store it in the refrigerator for 30 days before direct sowing. Keep the soil evenly moist until germination, which should occur within 10-15 days. The treated seeds can also be started indoors 6-8 weeks before the last frost of spring; plant the seeds on the surface of a flat, keeping the moisture consistent and the temperature around 65 degrees F. Transplant seedlings to 15-18” apart. This plant adapts to nearly any soil, including sandy or rocky areas; it is an excellent choice for borders, roadsides, or wildflower plantings.
