Rudbeckia grandiflora |
Rudbeckia grandiflora, commonly called rough coneflower, [1] is a species of flowering plant in the family Asteraceae.
It is a perennial from a woody base, growing to around 120 cm tall. It produces relatively large inflorescences, with 12-25 yellow ray flowers, each around 3–5 cm long. It blooms from late spring into summer. [2] [3]
It is native to North America, where it is found primarily in the south-central United States, including a disjunct population in northwest Georgia. [4] [5] The other populations farther east, all small and isolated, are believed to have originated from human introductions.
Its typical natural habitat is in prairies and open woodlands. [2] [3]
