Its height makes it a perfect selection for the back of the perennial border. A fine addition to butterfly, cut flower, cottage and yellow color theme gardens. an amazingly colorful display for an extended period beginning in late-summer.

Growing Preferences
Rudbeckia Herbstsonne is very easy to grow in most any well-drained but moist soil in full sun or part shade. Provide at least 6 hours of direct sun for best flowering. As with many other perennial plants, constantly soggy or wet soils can be problematic. Heavy, dense clay soils should be amended with organic matter to improve drainage.
Plant Long & Prosper!
