Description

The Blue Oat Grass is an evergreen, blue clumping grass that grows 2' tall and 3' wide. Foliage is thin blue gray, wiry leaves that radiate from center of plant. Its showy tan flowers are on spikes 1'-2' above the foliage (flowers more common in cooler winter areas). This plant looks good alone as well as in mass plantings. It does well in full sun or light shade. Established plants need only occasional watering. It does best with well draining soil. The blue oat grass likes dry hill sides.

Water Saving Tip:

Check your irrigation controller once a month, and adjust as necessary.

Most plants require only one-third as much water in winter as they do in summer.
