Tickle grass

Botanical Description

Agrostis scabra, known as rough bentgrass, ticklegrass or hair grass, is a tufted, short-lived perennial in the family Poaceae native to much of North America and northeastern Asia. The slender, erect culms grow 20–80 cm tall from a small basal tuft, with most foliage concentrated near the base. The leaf blades are narrow, 1–3 mm wide and 4–15 cm long, with scabrous (rough) margins and surfaces; the ligule is membranous, 2–5 mm long, and pointed. The inflorescence is a very large, diffuse, open panicle that may occupy half or more of the plant's total height, with capillary, scabrous branches that often break off as a tumbleweed at maturity. The tiny one-flowered spikelets are 1.6–3 mm long, with purple-tinged glumes and a single floret lacking a conspicuous awn. The species colonises open meadows, rocky slopes, roadsides, recently burned areas and disturbed soils from sea level to over 3,000 m in mountainous regions.
