Black-eyed Susan

Black-eyed Susan flowers (Rudbeckia hirta) originate from North America and are the most well-known wildflowers cultivated today. They often cover open fields and often amaze passersby with their golden yellow blooms.

As a member of the Asteraceae (aster) family, the “Black-eyed Susan” gets its name from the dark purple-brown centers of its Daisy-like inflorescence.

The plants can reach a height of more than 3 feet tall, with 6-inch leaves, stems over 8 inches long, and flowers 2 to 3 inches in diameter.

Black-eyed Susan flowers are available in orange-yellow, gold, red, and bronze and bloom from June through October. There are more than 40 different species[1] of black-eyed Susans. However, be aware that they can be territorial, as they tend to crowd out other flowers growing close to them.
