The present invention provides varieties of fertile Miscanthus that have greater water deficit tolerance, greater vigor, greater cold tolerance, later flowering, and/or higher biomass, i.e., greater biomass than a control Miscanthus plant, and methods for producing and using the said Miscanthus varieties. These varieties may be used to produce cellulosic biofuels, or to produce inbred or hybrid Miscanthus plants. Plant cells, seeds and other plant parts are also described.
