Chinese silvergrass

Miscanthus sinensis Anderss.

U.S. Nativity: Exotic
Habit: Herb

Synonym(s): Chinese silvergrass, eulalia, Chinese plume grass, zebra grass, eulaliagrass

Miscanthus sinensis is a tall, up to 12 ft. (3.7 m), densely-bunched grass that invades roadsides, forest edges, old fields, and other disturbed areas throughout the United States.
The leaves are long (up to 18 in. [45 cm]), slender, and upright-to-arching with sharp tips and rough margins. The midribs are silvery in color.
The terminal panicle is fan-shaped, long (2 ft. [0.6 m] in length), and silvery to pink in color. Flowering occurs in late summer.
Each fertile lemma in the panicle bears an awn that is 0.3-0.4 in. (8-10 mm) long and is spirally twisted at its base. It can also spread through rhizomes.
Ecological Threat
Miscanthus sinensis escapes from ornamental plantings and can form large clumps along disturbed areas, displacing native vegetation. The grass is also extremely flammable and increases fire risks of invaded areas. It is native to Asia and was introduced into the United States for ornamental purposes during the late 1800s.
