The genus RUDBECKIA has an extensive number of species, among which RUDBECKIA hirta is one. The sub-species RUDBECKIA hirta is one of a large number of flowers w/ the common name 'Black-Eyed Susan' Other common names include: 'Brown-Eyed Susan', 'Gloriosa Daisy', 'Brown Betty' and 'Ox-Eye Daisy'

Unlike so many other flowers, the RUDBECKIAS are not a worldwide group of plants, w/ all species being native to North America. As such it was commonly used by Native Americans for medicinal purposes including in the treatment of the common cold, flu, various infections, swelling and topically by poultice for snake bites. In modern times 'Black-Eyed Susans' symbolize encouragement and justice in the language of flowers. They would be the perfect gift to send to a friend going through rough times.

In the image seen here (mid day in late summer garden) I was photographing an immature RUDBECKIA flower (aka- 'Rud Bud') You can see several yellow petals (upper side of brown center) just beginning to show. These are fast growers though.....w/in a week of this photo this bud was a fully formed 'Black-Eyed Susan'
