Black-eyed Susans are one of those summer flowers we all enjoy seeing.  They are large, colorful, and cheery.  The yellow "petals" are actually called rays, a kind of specialized flower common to members of the Compositae family.  Each ray is its own flower, as are each of the brown flowers that make up the "eye" of black-eyed susans.  The leaves are long and narrow and the plant grows from 1-3 feet in height.  There are five species of Rudbeckia in Michigan, but the most common by far is R. hirta.
