Artemisia tridentata, commonly known as big sagebrush, is a perennial shrub native to the western United States. It typically grows between 3 to 6 feet tall and has distinctive gray-green leaves that are deeply lobed, giving it a trident-like appearance. This plant thrives in arid environments and is well-adapted to poor soil conditions. Big sagebrush plays a crucial role in its ecosystem, providing habitat and food for various wildlife species, including sage-grouse and deer. It also helps prevent soil erosion and contributes to the overall health of sagebrush steppe habitats, which are vital for many other plants and animals.
