- Comments
- Scratchgrass or alkali muhly, a perennial and warm-season grass, is fairly common at the lower elevations of the Watershed, especially in alkaline or saline flats and in ditches and along roads. Other habitats are damp ground by ponds and the floodplain of streams (especially the Rio Grande). Sometimes in towns Muhlenbergia asperifolia occurs by streets that have been salted during the winter. Although deemed a warm-season grass, it seeds mid to late summer on through mid fall. In the USA the species is common in all the Western states, somewhat less wide spread in the Great Plains. It follows the Rio Grande drainage through New Mexico to the Big Bend region of Texas, no father down stream
