Rudbeckia fulgida /rʌdˈbɛ.ki.ə ˈful̠ˡ.d͡ʒi.da/
Common name: Orange coneflower · Perennial coneflower · Goldsturm black-eyed Susan
Rudbeckia fulgida is a herbaceous perennial in the sunflower family (Asteraceae), native to the eastern United States. It bears golden-yellow, daisy-like flowers with dark brown central cones from midsummer into autumn, above clumps of dark green foliage. Unlike the often short-lived Rudbeckia hirta, it is a reliably long-lived perennial, making it a mainstay of perennial borders and prairie-style plantings. Its cultivar 'Goldsturm', introduced in 1937, was named the 1999 Perennial Plant of the Year.

Fun facts
- The cultivar 'Goldsturm' ("gold storm" in German) was named Perennial Plant of the Year in 1999.
- The species epithet "fulgida" means "shining" or "glistening" in Latin, describing its bright flowers.
- It spreads by rhizomes to form expanding clumps, unlike the tap-rooted Rudbeckia hirta.
- Its blooms attract butterflies and native bees, and goldfinches eat the seed heads in autumn.
