Lance-leaf tickseed grows in small clumps but forms extensive colonies. It is 1-2 feet tall and has leaves 3-4 inches long, opposite, sometimes alternate near the top where the leaves are fewer. Some of the leaves are deeply cut, almost forming 3 leaflets. Flower heads are yellow, 1-1 1/2 inches across. The yellow center or disc flowers stand out distinctly from the ray flowers, which appear to be attached just below them. Ray flowers are 4-lobed. The yellow, daisy-like flowers occur singly atop long, naked peduncles.
This native species has branching stems at base and often forms sizable colonies along roadsides and in old fields. A southern species, Greater Tickseed (C. major), 2-3' (60-90 cm) tall, has sunflower-like flower heads 1-2" (2.5-5 cm) wide and opposite leaves deeply segmented into 3 parts, appearing as a whorl of 6. Nearly a dozen other perennial yellow-flowered Coreopsis species occur in the East.

Conditions Comments: Lance-leaved coreopsis is the most common coreopsis and is easy to grow. It is drought tolerant but is not a reliable perennial. However, it self-sows readily and can become weedy. The showy golden flowers are nice in a vase and are a popular plant for visiting pollinators. It should have frequent deadheading to keep it in bloom well into the summer.

Propagation
Propagation Material: Clump Division , SeedsDescription: Plant seeds in early spring. Can also be propagated by division of basal rosettes or by seed. In the fall, lift a clump from the outer edge of the plant and separate the rosette. Remove a few of the leaves to reduce moisture loss, replant, and water thoroughly.
Seed Collection: Nutlets are mature and ready for collection about four weeks after the flowers wither. Watch the inner series of bracts; when they begin to darken, it is time to collect. Remove chaff and store in sealed, refrigerated containers. Storage life is at least three years.
Seed Treatment: Seeds of this species benefit from light and KNO3 enrichment for germination.
Commercially Avail: yes
Maintenance: May be selectively thinned to improve appearance by removing clumps from the interior of the planting. Mulching helps conserve moisture and control weeds.
