Blue Fescue grass (Festuca glauca) is ornamental grass with silvery blue foliage and pale green flowers which slowly fade to a light brown or tan as they mature. They are drought tolerant and remain hardy in USDA zones 4-8.
With its wispy, fine texture and being easy to care for, gardeners have grown to love blue fescue grass. Unlike a number of other plants that are grown as ornamental grasses festuca glauca is a true perennial as it is classed under the Poaceae family.
Mature plants grow between 9-12 inches tall and approximately 18 inches wide when grown in ideal locations.
Providing the proper, healthy environment will always be the key to growing any plant successfully and that remains true here. Your blue fescue ornamental grass is more likely to live a healthy life when placed in a location that receives full sun and receives good air circulation. Nutrient lacking soil is not a problem as long as the soil is well draining.
In hotter climates they may prefer an area that is partly shaded.
This is a plant that prefers consistently moist soil that is well draining. It does not tolerate soggy conditions and if exposed to these conditions for a prolonged amount of time the plants healthy may suffer. Mature plants are drought tolerant and require less water than newly planted blue grass.
Removing spent foliage is always a good idea to allow room for healthy growth and air circulation. In the early spring cut back the foliage within a few inches of ground level. Seeds from the flower head may spread and cause the plant to self-seed, which isn’t a problem, unless you are not interested. If that is the case dead head the flowers before they have the opportunity to do so.
