Description:

Golden yellow flowers with dark buttons from August through September on 70 cm (28") 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 clonally 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.

How To Grow 3700 seeds/gram. This robust perennial will turn heads wherever planted and withstand more heat and drought than most. Sow this type outdoors from September through October - select a site in full sun. This fall sowing allows any dormant seed to be naturally stratified over the winter. Seed can be started indoors in a soil-less mix from February to the beginning of March. Germinates at 20 C (70 F) in 14 to 21 days. Grow on under lights at a slightly cooler temperature before hardening off and transplanting outdoors to a sunny spot. Space 30cm (12") apart in the garden.

Requires Stratification For the seed from many native plants, late fall is the best time to sow seed directly outside. Why you ask? Simply put, many native plants produce seed that is viable but dormant. This means that while the seed has all the internal structures and nutrients required to germinate, the seed coat is so hard, water cannot pass through it and initiate germination. When seed is in this state, it is known as being dormant. Seed dormancy is a naturally selected for trait that protects the seed of many plants allowing them to safely overwinter and then be ready to sprout in more favourable conditions in spring. The remedy to naturally breaking seed dormancy is typically the passing of time. In particular, seed overwintering outside and experiencing the natural freeze thaw cycles that occur in late fall, winter and early spring. This dormancy breaking process is called stratification.
