Xylorhiza tortifolia, commonly known as Mojave aster, is a perennial herb or subshrub native to the arid desert scrub and rocky slopes of the Mojave Desert, Sonoran Desert, and Great Basin Desert in the southwestern United States and northwestern Mexico. It thrives at elevations between 787 and 6562 feet, where it is adapted to survive in harsh, dry conditions with poor, sandy soils. The plant typically reaches 24-31 inches in height and is characterized by its spiny, gray-green leaves and showy daisy-like flowers with lavender, pale blue, or white petals surrounding a yellow center. The bloom period extends from March to June, during which the flowers attract a variety of pollinators.

Mojave aster is valued for its drought tolerance and ability to add color to dry landscapes with its vibrant flowers. It is often used in native plant gardens, xeriscaping, and habitat restoration projects. In cultivation, it requires minimal water once established, well-drained soils, and full sun exposure to thrive. While it is not commonly afflicted by diseases, overwatering can lead to root rot. The Havasupai people have traditionally used Mojave aster for incense and fragrance, highlighting its cultural significance.CC BY-SA 4.0
