coreopsis auriculata - Lobed tickseed

Lobed Tickseed (Coreopsis auriculata) is a hairy perennial herb that grows from 8 to 24 inches tall. It has erect or ascending stems. The leaves are mostly basil, petioled, ovate to broadly elliptic. They are up to 3 inches long and usually have a pair or small lateral lobes at the base of the blade.

The flowers are yellow ray flowers up to 1" long and the tips are deeply 4-lobed. The disc is yellow, about 0.5" wide. The corollas are 5-toothed with about 8 outer involucral bracts to 0.4" long. The heads radiate and are either solitary or few on long, leafless stalks. Found from April to June in open woods across most of the southeastern US. 

The species auriculata means "with basal lobes, shaped like a mouse ear." This also give rise to another common name - Mouse Ear Coreopsis.

The flowers and stems can produce a reddish-orange dye.
