Rudbeckia fulgida var. sullvantii '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.
Use it between other plants in a flower border, as it tolerates light shade, to extend the flowering season late into the year. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
For best results grow Rudbeckia fulgida var. sullvantii 'Goldsturm' in bold drifts in moist but well-drained soil in full sun. Divide congested clumps from autumn to spring.
