Psathyrostachys juncea, commonly known as Russian wildrye, is a drought-resistant perennial bunchgrass native to the steppes and semi-arid regions of Russia and Central Asia. It has been successfully introduced to parts of Canada and the United States, particularly the Great Plains, for agricultural purposes. This grass typically grows in tufts reaching up to 3 feet tall and is characterized by its dense basal leaves and deep, fibrous root system, which contribute to its resilience in challenging environments.

Russian wildrye is valued for its ability to provide forage for livestock, especially in arid regions where other grasses may fail. Its deep roots aid in soil stabilization, making it an excellent choice for erosion control. The plant is well-adapted to a range of harsh conditions, including drought, cold temperatures, and high soil salinity. It is not generally invasive and can be used in integrated planting schemes, such as alternating rows with legumes, to enhance soil nitrogen and improve forage quality. In cultivation, Russian wildrye performs best in full sun and requires well-drained soils. It is relatively low-maintenance once established but may require supplemental watering during prolonged dry spells.CC BY-SA 4.0
