Saltbush is ideally suited to the harsh Nullarbor environment. It is stiff and papery in appearance and does not grow more than about one metre in height.
Saltbush accepts moisture from the atmosphere through its leaves and is able to absorb the equivalent of its own weight in a single day.
The bluebush, to a lesser degree, shares this attribute. Heavy dews are frequent on the Nullarbor and are almost as serviceable as good rains to these plants.
