Eremophila maculata (Spotted Emu Bush)
I have had this pretty dark pink form growing for 20 years in a windbreak/screen. I established it by watering with drippers as it was growing in amongst existing Eucalyptus (mallee trees). Over the years I have taken numerous cuttings from the bush and trimmed where webbing caterpillars had defoliated small branches. At flowering it gives a fabulous display and seems to have some flowers for most of the year with the major flowering in spring and autumn.
In our terrible soil the plant is about 1.7m high and wide. Our rainfall is about 3oomm. The current drought situation does not seem to affect the plant given that there is little moisture in the subsoil.
