Goldsturm Rudbeckia Seeds | OSC Seeds

Approx. 50-75 seeds/pkt (3,700 seeds/gram)

Golden yellow flowers with dark buttons from August through September on 70 cm plants. Heat and drought tolerant and good for cut-flowers too! Controversy surrounds the heritage of Goldsturm. Some authorities assure us that Goldsturm is propagated vegetatively only (cuttings, division, etc.). We offer a seed true to the aesthetics of the named variety. Avoid high fertility and irrigate only when absolutely necessary. Water soil below foliage, if possible. Hardy to Zone 3. For many native and perennial plants, late fall is the best time to sow seed directly outside. Why you ask? Simply put, many of these plants produce seed that is viable but dormant. This means allowing seeds to naturally stratify over winter will wake up the dormant seed for best results.
