This is a planting next to the driveway at the old house site. It's been there over a dozen years. Unlike R. hirta, R. fulgida really likes moisture. It tolerates/ survives drought but not happily, responding by drooping dramatically. These Rudbeckia have been under 2 feet of water for 2 days or more on more than one occasion, and didn't mind a bit.
Rudbeckia fulgida was one of the few plants that survived in the clay subsoil that remained after the site was cleared for the house and has put on a good display year after year. It's easy to see why it's so popular.
