Summary

Eriocoma occidentalis subsp. pubescens, commonly known as Western Needlegrass, is a perennial herb native to the western United States, where it is found in a variety of habitats including open woodlands, grasslands, and sagebrush steppe. This grass typically grows to a height of 1 to 3 feet (0.3 to 0.9 meters) and is characterized by its narrow, rolled leaves and dense, bristly flower spikes that appear from late spring to early summer. The flowers are not particularly showy, but the seed heads are distinctive with long awns that can catch the light and add texture to the landscape.

Western Needlegrass is valued for its adaptability to a range of soil types, from well-drained sandy soils to heavier clay loams. It is drought-tolerant once established, making it a suitable choice for xeriscaping and restoration projects. It is also used for erosion control and as forage for wildlife and livestock. In cultivation, it requires full sun and minimal water, and it is relatively low-maintenance. While it is not typically plagued by serious diseases or pests, overwatering can lead to root rot.CC BY-SA 4.0
