Miscanthus, commonly known as silvergrass, is a genus of flowering plants in the grass family Poaceae, placed in the order Poales. The genus encompasses approximately 14 accepted species of perennial grasses native to Africa, Eurasia, and the Pacific Islands, with distribution concentrated across East Asia (China, Japan, Korea), South and Southeast Asia, and parts of southern Africa.
Plants in this genus are typically tall, clump-forming grasses bearing feathery, silky plumes of flowers on stalked spikelets — the morphological feature that gave the genus its name, from the Greek miskos (stem) and anthos (flower). Several species are among the tallest ornamental grasses in cultivation, making Miscanthus a staple of temperate garden design.
The genus is taxonomically placed in the subfamily Panicoideae within Poaceae. A number of species formerly classified in Miscanthus have since been moved to related genera including Miscanthidium, Saccharum, Spodiopogon, and Pseudopogonatherum.
Beyond horticulture, certain species — most notably Miscanthus sinensis and the sterile hybrid Miscanthus × giganteus — attract significant interest as dedicated bioenergy crops owing to their high biomass yields, low input requirements, and capacity to sequester carbon. Miscanthus sinensis is the most widely cultivated species and has naturalized across New Zealand, North America, and South America.
Etymology
The genus name Miscanthus derives from the Greek words miskos, meaning "stem" or "stalk", and anthos, meaning "flower". This refers to the characteristic stalked spikelets found on plants of this genus, which carry the feathery flower clusters on long, slender stems.
Distribution
Miscanthus is native to Africa, Eurasia, and the Pacific Islands, with its centre of diversity in East Asia — particularly China, Japan, and Korea. Individual species extend through the Indian subcontinent (Nepal, Bhutan, Assam), Southeast Asia, and southern Africa. Miscanthus sinensis, the most widespread species, has been introduced and naturalized in New Zealand, North America, and South America.
Cultivation
Several Miscanthus species and cultivars are widely grown as ornamental grasses in temperate gardens worldwide, prized for their tall, arching foliage and showy late-season plumes. Beyond ornamentals, Miscanthus × giganteus (giant miscanthus) and M. sinensis are cultivated as biomass energy crops for their exceptional productivity and low-input requirements on marginal land.
