Rudbeckia fulgida var. sullivantii 'Goldsturm' bears wide, black-eyed, single, yellow daisy flowers with cone-shaped, black-brown centres from August to October. It's ideal for creating a splash of late-summer colour in ornamental borders and works well in prairie-style schemes with ornamental grasses. It's short enough not to need staking, and doesn't spread so fast that frequent division is necessary, making it a very easy-care plant.
