Native to lower elevations in southern Arizona and northern Mexico, this clump grass has unique fine-textured chartreuse foliage. Its soft, billowy texture provides a wonderful foil for bold succulents and cacti. The light green flowers are fairly insignificant. This grass spreads slowly from underground stems, eventually forming a large clump. It thrives in full sun or part shade, and is adapted to a wide range of soils. It appreciates moderate to ample summer irrigation.
