More Plants for Dry Conditions
I was thinking about the list so far realizing that there are many plants which fit this category which I do not actually know apart from what I read in specialist books. There is great information available if it can be found. In most cases it is important to remember that these plants need to have good drainage. Raising the planting hole or the garden bed as little as 100mm (4″), will provide sufficient drainage.

Plants That Tolerate Dry Conditions
A list like this could have some surprising species. Drought tolerance is a subjective thing in a plant. It depends on the amount of natural rainfall, whether it fell in the usual time of the year for the area, whether the garden is mulched, what shade is available, protection from hot drying winds etc. It is easier to change the conditions in a garden than in a paddock. In general, if conditions have been average then these plants should manage 3-4 months of summer with little extra water. Of course if some water is available they will do better. One deep watering is far more beneficial than many light weekly waterings in any situation. Be aware that many Australian native species have a ‘quiet’ time during summer and manage on little water as a result. Excessive watering in this case is likely to kill the plants. It pays to know about the plants that are grown.
This list is intended for garden culture. These are some plants I know of. There will be many that can be added.

Eucalyptus phenax (White Mallee)
I was working in the Nursery this morning and could hear what I thought was the neighbour’s air conditioner. It was there in the background but I could not track the other noise that was there. When I looked up above my head I saw it. There were hundreds of bees in the canopy of the tree because it was smothered in flowers.
I love our local mallee trees. Against all odds they put on beautiful new new leaf growth and flower prolifically when everything else has ‘quietened down’ for the hot summers we have here. We seem to have three different species and they flower consecutively. If I was into bee keeping, it would be worth while having hives here for about three months. These are moderately fast growing plants suitable for limestone soils.
Eucalyptus gracilis (White Mallee)
Eremophila subteretifolia

Eremophila subteretifolia
When I first began growing Eremophilas (Emu Bushes) I tried those that were considered to be hardy and available through plant sales put on by the Australian Plants Society. 20 years ago there were not many species in the nursery trade.
Eremophila subteretifolia is ground cover plant covering about 3 metres and with the occasional branch rising to about 25 cm. It is mostly quite prostrate and has a cascading effect on embankments. It is not a vigorous plant so is easily contained to an area. This is another of those ground covering plants which could be used as a substitute lawn where it would not be walked over.
This species is very drought tolerant and frost hardy.
The plant has orange tubular flowers which are enjoyed by Honeyeaters, particularly Red Wattle Birds and New Holland Honeyeaters.
Eremophila splendens
Eremophila splendens
I find Eremophila splendens to be a spectacular plant when in flower. The bright red flowers glow against the foliage which is quite hairy similar to some Eremophila glabra forms. This plant needs very good drainage. It is either a sprawling low plant or can be quite upright.
Eremophila splendens is restricted to Shark Bay about midway along the Western coast of Western Australia. It grows on the heathlands with Thryptomene and Melaleuca.
Last winter I lost some small plants to frost but I want to try again in a more sheltered location where the canopy of mallees may protect them. This is a plant that needs to be pruned aftyer flowering to encourage new and dense growth. Mature plants get very leggy and have sparse foliage without the pruning.
