Rudbeckia triloba

Brown-eyed Susan

Categories: Herbaceous Perennial

A short-lived perennial, it self-seeds readily, flowering in its second year. Its abundant bright yellow flowers are flat, one to two inches across, with jet black centers that fade to brown. Blooming from late summer until hard frost, Rudbeckia triloba reaches two to five feet tall and becomes bushy if not crowded by other plants.
