Tetradymia glabrata, commonly known as Littleleaf Horsebrush, is an erect, bushy shrub native to arid regions, including the Great Basin and Mojave Desert in the western United States. It is typically found in sagebrush communities, pinyon-juniper woodlands, and desert scrub habitats. This shrub can reach over one meter in height and is characterized by its white woolly stems and narrow, pointed leaves that are usually no longer than a centimeter. During its flowering season, which occurs in late spring to early summer, Tetradymia glabrata produces inflorescences bearing up to seven flower heads, each with four yellow cream flowers that are modest in showiness.

Littleleaf Horsebrush is valued for its drought tolerance and ability to thrive in poor, well-drained soils, making it suitable for xeriscaping and naturalistic plantings in arid regions. It is also used for erosion control due to its deep root system. However, gardeners should be aware of its toxicity, particularly to livestock such as sheep, as it contains harmful compounds like furanoeremophilanes. It requires minimal maintenance once established and prefers full sun conditions. Despite its benefits, caution is advised when planting near grazing areas due to its toxic nature.CC BY-SA 4.0
