FAMILY NAME COMMON
FAMILY SCIENTIFIC NAME
Miscanthus sinensis is a highly variable robust perennial grass that can grow to 2-3 m (6.5-10 ft.) in height. It is usually found in large tufts. The branches are very flexible and spread or droop. The leaves are elongate and can measure 1 m (3 ft.) in length and 2.5 cm (1 in.) in width. The leaves have a silver white midrib. The tips of the leaves are sharp and recurving. The fan-shaped terminal panicle is 15-61 cm (6-24 in.) long and can be silvery to pale pink in color. The branches of the panicle are erect or ascending. These panicles reach full maturity in the fall. The glabrous spikelets are very small, yellow-brown in color and encircled at the base with white or purple-colored hairs. The lemmas measure 2-3 mm (0.1 in.) long. Each fertile lemma bears an awn that is 8-10 mm long and is spirally twisted at its base. *There are a wide variety of cultivars of this plant which may not fit this exact description.

Miscanthus sinensis has the ability to reproduce vegetatively via rhizomes. It can also be dispersed longer distances through its mechanically or wind-dispersed seeds. Though some of the horticultural varieties do not self-seed, many of them still have this ability.
Miscanthus sinensis is native to China, Japan and Korea. In the United States it has been reported from Massachusetts to Florida and west to Louisiana and Missouri, as well as from California and Colorado. In New England this plant has been reported in Massachusetts, Connecticut and Rhode Island.
HISTORY OF INTRODUCTION IN NEW ENGLAND
Miscanthus sinensis is a horticultural introduction that has the ability to naturalize from its original site of planting. Though the exact first date of introduction into this country is unknown, more than 50 cultivars of M. sinensis have been introduced since 1980.
HABITATS IN NEW ENGLAND
Coastal Grassland, Edge, Open Disturbed Area, Roadside, Vacant Lot, Yard or Garden. Miscanthus sinensis depends on disturbance to become established. It is usually found along the edges of roads and woods.
The invasiveness of this plant is still being assessed, but it does have the ability to form large clumps that can displace native species.
