Maryland State Flower (Floral Emblem)

Black-eyed Susan

Maryland State Flower - Black-Eyed Susan

(Rudbeckia hirta)

Adopted on April 18, 1918.

Inspired by the 1893 World's Fair (World's Columbian Exposition) in Chicago was the motivating factor to a group of women at the Maryland Agricultural College in 1896. They thought that Maryland should have an official state flower and they thought it should be the black-eyed Susan.

The Black-eyed Susan, (Rudbeckia hirta,) has been the official Maryland flower since 1918 when it was designated the "Floral Emblem" of Maryland by the General Assembly (Chapter 458, Acts of 1918; Code State Government Article, sec. 13-305)

In his Species Plantarum (1753), the Swedish naturalist Linnaeus described and named the flower Rudbeckia after Olav Rudbeck and his son, both professors at the University of Uppsala, and hirta from the Latin meaning "rough hairy".
