The Rudbeckia fulgida var. sullivantii 'Goldstrum' is native to eastern north America and is commonly named orange coneflower or black-eyed susan. This perennial is a genus from the aster or sunflower family (Asteraceae or Compositae).
The Rudbeckia fulgida var. sullivantii 'Goldstrum' is a very strong plant that grows almost anywhere. It spreads quite fast by rhizomes. If you want to keep the black-eyed susan in one place it is wise to put a plastic rim around it. The orange coneflower also spreads through seed. The seedlings are easy to replace or remove so that is not a problem at all.
Bees, butterflies and bumble bees are very attracted to this orange coneflower. The nice thing about the black-eyed susan is that it blooms quite late in the season when most other plants have finished blooming. On top of that the Rudbeckia fulgida var. sullivantii 'Goldstrum' blooms for a long time and richly.
The black-eyed susan has rigid, hairy stems that stay upright very well. The flowers are very suitable as cut flowers. The orange coneflower prefers a position with full sun or part shade, is very hardy and tolerates salt.
