autumn moor grass
S Europe (Italy, Balkans, Turkey; limestone meadows, rocky grasslands, open woodlands; chartreuse-green evergreen mound; shade-tolerant grass; z5)
Overview
Sesleria autumnalis is an evergreen perennial grass reaching 12-18 inches (30-45 cm) tall with a spread of 12-18 inches (30-45 cm) and a dense, mounding, clump-forming habit. Native to southern Europe—Italy, the Balkans, and into Turkey—in limestone meadows and open woodlands, it produces narrow, chartreuse-green to yellow-green leaves 0.25 inch (6 mm) wide that form a dense, arching mound. Silvery-white flower spikes 2-3 inches (5-8 cm) long appear above the foliage in August-October on slender stems. Growth rate is moderate. Hardy to zone 5. The chartreuse-green foliage is the primary feature—brighter than most grasses and maintaining color well into winter. Cool-season grass that greens up early in spring. Tolerates more shade than most ornamental grasses. Non-invasive clumper.
