Rudbeckia triloba
Common name: Brown-Eyed Susan
Flowers of the Brown-Eyed Susan are a bit smaller than those of other Rudbeckia species, but they are so abundant on each plant that they still put on quite a show! They bloom mid to late summer for 1 to 2 months. Bloom time can be extended by deadheading. Although it can tolerate part shade conditions, plants tend to flop over and flowers are less abundant than in full sun. This plant is short-lived but will readily reseed.
