Upland Bentgrass
Agrostis perennans

This is a perennial grass about ½–2½' tall that develops either individually or in loose tufts of unbranched leafy culms. In sunny habitats with fertile soil, this grass is taller and more stout, while in shaded habitats with poor soil it is shorter and more delicate. The culms are light green, terete, slender, and glabrous. The longer blades of lower leaves have a tendency to droop, while the shorter blades of upper leaves are more stiff and straight. The leaf blades are 1-6 mm. across and 2-10 inches long; they are medium green or grayish green, flat, and hairless. The leaf sheaths are medium green or grayish green, hairless, and open.
