Common Mistakes
- Misspelling: 'rudbekia', 'rudbeckiah'.
- Mispronunciation: /ruːdˈbɛkiə/ (with a long 'u').
- Using it as a common noun for any daisy-like flower.

The genus was named by Carl Linnaeus in honour of his botany teacher at Uppsala University, Olof Rudbeck the Younger, and his father, Olof Rudbeck the Elder.
Yes, particularly the more compact cultivars. Ensure the pot is large enough and has good drainage, and water regularly as pots dry out faster than garden soil.
