Rudbeckia fulgida var. sullivantii 'Goldsturm'
Rudbeckia fulgida var. sullivantii 'Goldsturm', wow what a mouthful for what is an easy, unfussy plant. Thank goodness it is most commonly called Rudbeckia 'Goldsturm' However, if its name was based on the esteem it is held within the gardening world, it is probably deserving of such a grand name, it would make many gardeners top ten herbaceous perennials. Confirmation of this is it being an A.G.M. awarded plant.
The 12 cm black-eyed, deep yellow daisy-like flowers that have an incredibly long flowering season, from mid-summer right through to the middle of autumn, when the first severe frosts arrive. These flowers with the black prominent conical disk lead to its common names of 'Black-eyed Susan' and 'Coneflower' If the seed heads are left on the plant over winter they add an extra period of interest and a feed source for birds.
The short bushy clump-forming plant has erect stems bearing narrowly ovate leaves, meaning the plant requires no staking. When flowering it reaches 60 cm in height. A spectacular sight if planted on mass and is also excellent as a cut flower
It is very easy to grow and likes full sun or partial shade and prefers heavier soils than its close cousin Rudbeckia fulgida var. deamii. R. Goldsturm is an excellent choice for improved clay soils but will be tolerant of most other soil types.
