"Rudbeckia subtomentosa, or Sweet coneflower, is a herbaceous perennial in the daisy family. Sweet coneflower prefers medium moisture, well-drained loam or sandy loam and full or partial sun. However, it is an easy going plant and tolerates hot and humid summers, some drought, clay soil, and is deer resistant. It does like good air circulation and, to encourage additional blooming, you should deadhead spent flowers. Also, the tall stalks may require some support, especially if the plant is grown in a shady area or given too much water or fertilizer. It is a good choice for rain gardens, borders, cottage gardens and naturalized areas. Sweet coneflower will grow to 3 to 5 feet tall and display daisy-like, 3 inch, yellow flowers with dark brownish-purple center disks on branched stems. The flowers faintly smell of anise, hence the common name." (North Carolina Extension)
