Lanceleaf Tickseed (Lanceolata)

The Lanceleaf Tickseed (Lanceolata) is generally described as a perennial forb/herb. This is native to the U.S. (United States) has its most active growth period in the spring and summer . The Lanceleaf Tickseed (Lanceolata) has green foliage and inconspicuous yellow flowers, with an abuncance of conspicuous black fruits or seeds. The greatest bloom is usually observed in the late summer, with fruit and seed production starting in the fall and continuing until fall. Leaves are not retained year to year. The Lanceleaf Tickseed (Lanceolata) has a moderate life span relative to most other plant species and a moderate growth rate. At maturity, the typical Lanceleaf Tickseed (Lanceolata) will reach up to 2 feet high, with a maximum height at 20 years of 0 inches.

The Lanceleaf Tickseed (Lanceolata) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by container, seed. It has a moderate ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -8°F. has low tolerance to drought and restricted water conditions.

Uses of : Landscaping, Medicinal, Culinary, etc.

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.

General Characteristics

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.

Required Growing Conditions

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.

Cultivation and Care

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.

General Upkeep and Control

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 after the seedlings are established and annually thereafter. The initial mowing should be delayed until after seed set. Lance-leaf coreopsis can tolerate regular mowing during the summer and fall. However, if the plants are allowed to regrow after the initial mowing, they will usually flower sporadically throughout the summer. A fall mowing is recommended.
