Coreopsis lanceolata - Bedding Plants

Lance-leaf tickseed grows in small clumps but forms extensive colonies. It is 0.3m tall. The yellow center or disk 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 in Northamerica native species has branching stems at base and often forms sizable colonies along roadsides and in old fields.
