What is bluebush?

Bluebush (Maireana sedifolia), also known as bluebush saltbush, is a shrub native to Australia. It is commonly found in arid and semi-arid regions, and is well adapted to withstand drought and high levels of salinity in the soil.

Bluebush grows up to 2-3 meters tall and has small, stiff, bluish-grey leaves that are covered with fine hairs to prevent water loss. The plant's small flowers are green and inconspicuous and give rise to small fruit capsules that contain tiny seeds.

Bluebush plays an important role in its ecosystem by providing shelter and food to various wildlife, such as birds, insects, and small mammals. The plant is also used for various purposes by Indigenous Australians, such as for making baskets, firewood, and medicinal preparations.

In recent years, bluebush has gained interest as a potential source of biofuel, due to its ability to grow in harsh environments with low water and nutrient availability. Additionally, bluebush is being studied for its potential in phytoremediation, or the ability to remove heavy metals and other pollutants from soil.
