Blue Oat Grass is a cool-season grass. Cool-season grasses put on most of their growth in spring and then hold their height and form as the heat of summer sets in. These grasses look great all winter long. Unlike most shrubs and flowers Blue Oat Grass can give you 12 months of interest as it is evergreen to semi-evergreen.  To clean up its appearance it can also be pruned if desired in early spring like other grasses to 2 inches from the ground.
 
Care:
Very easy to grow. Keep well-watered the first year to establish a strong root system. Apply an all-pupose fertilizer in spring (after pruning or planting) when new growth appears. 
 
If growing in pots, more watering will be required. In the heat of summer, daily deep watering is recommended.  In winter, water once a month to keep the plants from dehydrating due to frost.
