- Black-eyed Susans are lovely planted in mass - a great choice for wildflower meadows.
- Rudbeckias do best when they have sun all day.
- This is a drought resistant plant, but performance will improve when plants are watered during dry spells.
- Annual, perennial, and bienial forms are readily available. Even the annuals will come back year after year because they are eager reseeders. Biennials tend to be showy and weak on alternate years.
