Artemisia tridentata subsp. wyomingensis, commonly known as Wyoming big sagebrush, is a deciduous shrub native to the sagebrush steppe ecosystem of the western United States, particularly in states like Wyoming, Montana, and parts of the Great Basin. It typically grows to a height of 2 to 4 feet (0.6 to 1.2 meters) with a similar spread. The shrub has a rounded form with silvery-gray foliage and a distinctive three-lobed leaf pattern. Wyoming big sagebrush blooms with inconspicuous yellow flowers in the late summer to early fall. The plant is not particularly showy, but its foliage provides a unique texture and color contrast in the landscape.

Wyoming big sagebrush is valued for its hardiness in arid conditions and its role in habitat restoration and erosion control on disturbed lands. It is drought-tolerant, requiring minimal supplemental water once established, and prefers well-drained soils with full sun exposure. This shrub is also used in xeriscaping and as a windbreak in suitable regions. While it is not commonly used for ornamental purposes, it can be a practical choice for naturalistic plantings. Gardeners should be aware that it can become quite large and may spread if not managed. Additionally, it can be susceptible to root rot in poorly drained soils and may attract sagebrush-specific pests such as the sagebrush defoliator moth.CC BY-SA 4.0
