Festuca glauca 'Blue Whiskers'

Blue Whiskers blue fescue

Fine, silvery-blue blades form a rounded mound, with airy yellow-green flowers aging to tan above the foliage in early summer. This compact grass brings cool color and fine texture to sunny edging, rock gardens and containers. Good drainage matters more than rich soil; divide aging clumps in spring when needed.
