Question: what is the difference between black eyed susans and brown eyed susans?
Answer: Brown-eyed Susan, Rudbeckia triloba. ... The name “triloba” comes from the dark green, somewhat hairy basal leaves that are divided into three oval parts. This plant is similar to the very common black-eyed Susan (R. hirta), but is taller, flowers later and over a longer period of time and has much smaller flowers.
