Did you know
- The genus was named by Linnaeus in honor of his teacher Olof Rudbeck and his son, both professors at Uppsala University.
- It produces hundreds of small daisy-like flowers per plant, creating a massive display that overwhelms its more famous cousin, black-eyed Susan.
- The 'triloba' in its name refers to the three-lobed lower leaves, though upper leaves are often simple and unlobed.
- Goldfinches are especially fond of its seeds and can often be seen clinging to the dried flower heads in winter.
- It readily self-sows and can colonize disturbed ground, making it an important early successional species in forest openings.
