Glossopetalon spinescens var. planitierum, commonly known as Plains Greasebush, is a deciduous shrub or subshrub native to the arid and semi-arid regions of the Southwestern United States, including desert grasslands, chaparral, and arroyos. It typically grows to a height and width of 3 feet (0.9 meters), forming a compact, rounded shape. The plant is characterized by its small, leathery leaves and spiny branches. During the spring, it produces inconspicuous white flowers that are followed by small, dry fruits that may persist on the plant.

Plains Greasebush is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and naturalistic plantings in arid regions. It is also used for erosion control due to its dense growth habit. In cultivation, it requires minimal maintenance, thriving in full sun with low water needs and well-drained soils. While it is not commonly found in ornamental horticulture, its resilience and adaptability make it a practical option for challenging sites.CC BY-SA 4.0
