Orange Coneflower - Rudbeckia fulgida


Family: Asteraceae – Aster family Genus Common Name: Coneflower Native Status: Native
Rudbeckia fulgida - Orange Coneflower. This species, like many members of the 22-species Rudbeckia genus, are frequently called 'black-eyed Susan' because of their nearly identical appearance to R. hirta, the 'true' black-eyed Susan. Orange coneflower, Rudbeckia fulgida, itself is a highly variable species, with as many as 14 varieties. I believe this is R. fulgida var fulgida, due to the shorter, wider ray petals, the minimal hair on the stems, and the distinct winged petioles of the alternating leaves.
