These two mechanisms are not developed in all species and many germinate under the constant temperature. E.maculata this procedure is very helpful. Contrary to what has been previously published, fresh seeds germinate better than old. Treatment of seed, soil and seedlings with Polyversum has proved to be very beneficial. Root systems on the first repotting were well developed.
Plants appear to be very compact with short internodes and many side shoots.
Polyversum seems to stimulate the growth through the root tissue. I sincerely recommend it for testing with many other Australian native plants. Sowing of Eremophila seed as described above can be a good alternative to vegetative propagation and can be used for breeding new cultivars and propagation of the rare species.
