Eremophila maculata (Spotted Emu Bush) Dark Pink form

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.

Eremophila glabra variety tomentosa (Emu Bush)

This is one of my favourite Eremophilas. The leaves are grey green and are softly furry which can be seen closeup to the plant (hence the variety name ‘tomentosa’). A microscope would give an even more dramatic view. With the bright red flowers for contrast it is a great bird attracting plant.

This is a plant for a dry position and well drained soil. It is about one and a half metres tall by about half a metre wide. It needs to be pruned after flowering to promote more new growth which of course produces more flowers.

There are a number of Eremophilas which come into the category of ‘glabra’, and a few others which have grey or whitish foliage with green, yellow, orange/red flowers.

Eremophila maculata 'Wendy'

The Eremophila Study Group News Letter arrived and we are being encouraged to spread the good word about Eremophilas as hardy plants.

Plant hardiness is a relative term, I think. On the gardening programme Gardening Australia on ABC TV, the term is used by presenters in the Eastern States. A plant is described as hardy there, when I know that it is not hardy here unless it is regularly watered during the summer. A writer in the ‘Journal’, magazine of the Australian Plants Society, South Australia, prefers to refer to plants as being ‘adaptable’ or not. I tend to agree with him. There are many plants which would come into that category.

However, Eremophilas tend to be both hardy and adaptable. The issue that bothers many plants is over watering. Especially plants in pots. Watering regularly on a weekly basis as our water restrictions impose on us will spell disaster for many native plants, especially those that have a form of summer dormancy. Another issue is drainage which must be very good for Eremophilas.

The photo above is a selection of Eremophila maculata ‘Wendy’ which has reddish buds which open to dark pink. Tip pruning and trimming produces a bushy plant and many flowers.
