Coreopsis lanceolata
Features solitary, yellow, daisy-like flowers (1-2" diameter) with eight yellow rays (toothed at the tips) and flat yellow center disks. Flowers bloom atop slender, erect stems from spring to early summer. Narrow, hairy, lance-shaped leaves (2-6" long) appear primarily near the base of the plant in basal tufts. Lower basal leaves are mostly entire, while smaller stem leaves may be pinnately lobed. Plants in the genus Coreopsis are sometimes commonly called lanceleaf tickseed in reference to the resemblance of the seeds to ticks. Many excellent cultivars of this species are available in commerce.
