'Goldsturm' Black-Eyed Susan (Rudbeckia fulgida var. sullivantii 'Goldsturm'): Classic Perennial

'Goldsturm' Coneflower: The Gold Standard for Late-Summer Color

Few perennials have earned such universal acclaim as Rudbeckia fulgida var. sullivantii 'Goldsturm'. This 1999 Perennial Plant of the Year winner produces a profusion of large, golden-orange daisies with dark chocolate-brown centers from midsummer into fall—typically 7–8 weeks of nonstop bloom. The sturdy, 18–30 inch stems rarely need staking, and the plant forms neat, slowly expanding clumps.

Why It's a Garden Staple

'Goldsturm' combines reliability, long bloom season, and ecological value. Native to North American moist meadows and open woods, it supports pollinators, provides seeds for birds, and self-sows modestly in cultivated soils. Its tidy clumping habit (1–3 feet tall and wide) suits mixed borders, cottage gardens, meadow plantings, and massings. The flowers are excellent for cutting.

Growing Conditions

• Light: Full sun to part shade
• Soil: Average, slightly heavy but well-drained; tolerates clay
• Water: Medium moisture; consistent moisture improves bloom
• Hardiness: Zones 3–9

Care & Propagation

Deadhead to prolong bloom and reduce self-seeding. Divide clumps every 3–4 years in spring or fall to maintain vigor. Sow seed in cold frame in early spring, or divide established plants.

Potential Problems

Generally robust. Watch for aphids, powdery mildew, leaf spots (Septoria, Ramularia), smut, rust, and slugs/snails on young growth. Good air circulation helps.
