Saltbush refers to a group of plants in the genus Atriplex, commonly found in arid and semi-arid regions. These hardy shrubs are well-adapted to saline soils and can thrive in harsh conditions where many other plants cannot. Saltbush plays a crucial role in preventing soil erosion and providing habitat for various wildlife. The leaves of saltbush are often grayish-green and can be covered in a fine layer of salt, which helps the plant manage excess salinity. Some species of saltbush are also used as forage for livestock, making them valuable in agricultural settings.
