Mulga bluebush is a valuable forage plant. It loses its leaves only under severe moisture stress. It is palatable and provides a source of protein when annual feed has dried. It responds well to small amounts of rain and produces a lot of bulk, particularly if rested after rain. Mulga bluebush is known to respond well to annual or biennial spelling for 6 months. Spelling allows new plants to establish and existing plants to increase in size.
Non-saline mulga, breakaway slopes and saline stony upland
Mulga bluebush is not as compact as some of the other bluebushes and can grow to 2m tall. It has robust, woody lower stems, but the new growth is flexible. The branchlets of the new growth are covered with fine hairs. The leaves are alternate, becoming pointed towards the tips. They are up to 2cm long, 1–2mm thick and covered with silky hairs. The flowers are small and are held between the leaf base and the stem. The seed capsule is woody with a close, woolly covering on the top, surrounded by a showy gold to bronze seed case with a wing up to 15mm across.
