Leymus triticoides, commonly known as Beardless Wildrye, is a perennial grass that is evergreen in mild climates but may die back in colder regions. It is native to a variety of habitats including grasslands, wetlands, and open forests in the Western United States and Northeastern Mexico. This species typically grows to a height of 1.3 meters and is characterized by its stiff, slender leaves that are green to blue-green in color and diverge from the stems at a noticeable angle. The inflorescence is a narrow, elongated spike up to 20 centimeters long, which is less showy than some ornamental grasses but adds a subtle texture to the landscape during its flowering season in late spring to summer.

Beardless Wildrye is valued for its ability to form dense, spreading mats through its rhizomatous growth habit, which makes it an excellent choice for soil stabilization and erosion control, particularly along waterways. It is also a key species in habitat restoration projects within California chaparral and woodlands, where it contributes to the ecological integrity of these areas. In garden settings, it is often used for naturalistic plantings, as a ground cover, or in meadow gardens. Beardless Wildrye is drought-tolerant once established, making it suitable for xeriscaping and low-water landscapes. It thrives in a range of soil types, from sandy to clay, as long as there is adequate drainage. While generally low-maintenance, it can spread aggressively in favorable conditions, so it should be planted with consideration of its ability to colonize an area.CC BY-SA 4.0
