Black-Eyed Susan
Black Eyed Susans are indigenous to many sections of the United States. They were introduced into Europe soon after Columbus’s visits and were named by Linnaeus in 1753. Linnaeus gave them the Latin name Rudbeckia Hirta after his mentor Olaf Rudbeck and hirta meaning rough, hairy. The plant was known and used by many Native American tribes. The Native Americans used the plant to wash sores and swellings, as a poultice for snake bites and for treating worms and colds in children.
In 1918, the Black Eyed Susan, Rudbeckia Hirta was designated as the Floral Emblem of the State of Maryland. Each year this flower has its moment of glory when a huge drape made of hundreds of black eyed susans is lifted onto the back of the horse that wins the Preakness – the second jewel of the triple crown of horse racing.
