A coarse, native biennial, or sometimes annual, with rough, hairy stems and foliage, the stems rather bristly-hairy, 1 to 3 feet high. Leaves thick, sparingly toothed or entire, oblong to lanceolate, the lower ones petioled, 2 to 7 inches long, one-half to 2 inches wide, the upper leaves sessile and narrower than the lower ones. Heads of flowers very showy, usually few or several borne on stout terminal and axillary stalks, each head 11/2 to 3 inches broad. Disk flowers purple-brown, forming a cone-shaped center to the head. Ray flowers ten to twenty in number, orange-yellow in color, or sometimes purplish brown or reddish at the base. Bracts of the involucres hairy, spreading or reflexed, much shorter than the ray flowers.
Native of the plains and prairies of the western states, now well established in meadows and fields throughout the east. Flowering from June to August. In meadows and hay fields it is frequently an obnoxious weed.

Black-Eyed Susan; Yellow Daisy - Rudbeckia hirta
The Common White Daisy (Chrysanthemum1 eucanthe-mum Linnaeus), perhaps even more abundant in meadows and fields, with its bright yellow center and white ray flowers, needs no description or illustration for its identification. Native of Europe and introduced very early into America and now thoroughly established in the northeastern states.
