Dr. Neville Brown has now developed "instant smoke" for growers who want to germinate the dormant seeds of wildflowers. In this invention absorbent paper is impregnated with fynbos-smoke-saturated water. The paper is dried and sealed in a polythene packet. When dormant seeds need "smoking", you add some water to the paper in a suitable container and soak the seeds you want "smoke-primed" in the smoke-water solution for 24 hours. In order to have the maximum effect in breaking seed dormancy, a range of natural germination stimulators has been added to the smoke solution to overcome other forms of seed dormancy found in many species such as the Strelitzia.
