Black-eyed Susan is a native perennial that produces daisy-like yellow or orange flowers from late spring until early fall.

Those brightly-colored flowers are a magnet for butterflies but not for deer. So that’s always a bonus!

It can survive in clay soil and is quite drought- and heat-tolerant once it is established.

Some varieties (such as Rudbeckia hirta) are very short-lived perennials so they are often treated as annuals. However, since they do self-seed, they will come back if you let some of the flowers go to seed.
