Rudbeckia goldsturm flowers are known generally as “black-eyed Susan.” The cheery yellow black-eyed Susan can be distinguished from other Rudbeckia spp. by its lanceolate hairy leaves and the long hairs on the stems; most of the leaves occur toward the base of each stem, and never have lobes. The species Rudbeckia fulgida (Orange Coneflower) is quite similar in appearance, but usually blooms later, and has style-tips that are shorter and more rounded. (By the way – The genus for coneflowers is named in honor of Olaf Rudbeck and his son, both professors of botany.)
Regeneration Process: Black-Eyed Susan reproduces by seed. It is pollinated by bees and flies. It also reproduces vegetatively by sprouting from the root crown.
