Discussion

Miscanthus sacchariflorus is native to the margins of rivers or marshes in temperate to north-temperate regions of eastern Asia, and appears to require cold and humidity for optimum growth. It has escaped from cultivation in various parts of the Flora region. It combines a large, plumose panicle with recurving leaves that turn orange in the fall.
