Canada wildrye is a tall bunchgrass that takes up a generous amount of visual space. If you are looking for some relatively quick visual screening, this grass is a good choice. Bonus, like other grasses it actually enjoys a modest amount of deer browse. Due to its moisture tolerance and quick growth rate, it's also a good choice for swales and to stabilize areas of the yard with periodic flooding. It grows well in poor soils, and is commonly used in restoration to stabilize road cuts and stream banks.
 
While somewhat similar to great basin wildrye, Canada wildrye prefers more moisture and doesn't get quite as tall (in my experience). Additionally, its seedheads have a somewhat nodding, fuzzy appearance. This tall grass provides a solid backdrop for tall or showy flowering plants such as: nettle-leaf giant hyssop, blue vervain, black-eyed susan, anise hyssop, pearly everlasting, wild hollyhock, and nuttall's sunflower.
