| ||Common Name: Grass-Ornamental|
Common Name (Alternative): Blue Oat Grass
Blue Oat grass looks like a miniature water fountain, with its densely packed leaves gently spraying upward and arching back downward at the tips. 'Sapphire' is similar to H. sempervirens, but has brighter, steel blue leaves which tend to widen as they mature.
In early summer, small, tan seed heads appear on tall stems held well above the foliage. In mild climates, the foliage is evergreen; it is semi-evergreen in colder zones.
Blue Oat Grass adds a small, coarse element to rock gardens, coastal gardens, or dry hillsides. It is also great in containers.

The best place to plant Helictotrichon is a dry sunny site. Once established, it will not require supplemental watering unless there is a drought. Trim back the old foliage to 3-4" in spring before the new growth emerges. Division is recommended every 3-4 years in spring to keep the plant looking fresh.
H. 'Sapphire' has demonstrated a greater resistance to the rust fungus compared to the species.
