Blue Fescue Grass

Festuca glauca

Blue Fescue
Groundcover

A small, tufted grass with fine, blue-gray blades that form a neat, round clump. It brings a cool color and fine texture to small spaces, but it is a cool-season grass, so it needs a sheltered spot to get through a Phoenix summer.

Living with it in the Phoenix Valley

Watering

Follow the shrub, groundcover and succulent schedule in our Landscape Care guide. It does not tolerate wet or poorly drained soil, which causes the clumps to rot from the center.

Pruning

Shear the clumps back by about a third in early spring so fresh blue growth can come in. Some people also trim off the flower stalks.

Heat

It prefers cooler weather and tends to decline in a long, hot summer. Clumps often brown out or thin after a few years; dividing and replanting keeps a planting looking full.

How our designers use it

Small spaces and pots

Its compact size suits containers, narrow beds and courtyard pockets.

Cool color contrast

Our designers like its blue tone beside blue-gray agaves and aloes, or against dark stone and steel.

Shaded edges

It holds up best along beds that get afternoon shade from a wall or tree.

Good to know

Around the pool

Soft and thornless with very little litter, so it is easy near water. Reflected heat off a sunny deck is hard on it; a shaded spot works better.

Lifespan

Expect to replace or divide clumps every few years. It is not a long-term plant in the low desert.
