Distinguishing traits. Blue fescue is relatively compact, forming a dense, rounded mound of blue-gray foliage. I like to think of blue fescue as modular — it looks great as a single specimen or massed in a field.
Blue fescue blooms, though somewhat insignificantly, in summer; golden inflorescences add height and a softer texture to the otherwise stiffer structure. When other grasses fade to a soft golden hue in fall, blue fescue keeps its soft blue color.
Popular cultivars include 'Elijah Blue', 'Blausilber' and 'Siskiyou Blue'.
