Importance:
This species is one of the bushes recognized in the Government Gazette No. 49556 as an essential part of the sheep diet required for producing certified Karoo lamb. Highly drought-resistant, it plays a critical role as forage during dry periods when most other plants have been grazed, even though it is not particularly palatable. Its new growth, however, carries a pleasantly aromatic flavour.
