Abstract: Using perennial grasses as feedstock for bioenergy industry is a new development direction of renewable energy. Awngrass (Miscanthus spp.) and silverreed (Triarrhena spp.) are C4 perennial tall grasses and native to China. Being a potential resource of bioenergy plants, they have received considerable attention in Europe but mainly been used for soil and water conservation, paper manufacture, feedstuff and so on in China. This paper reviews the biological characteristics, biomass quality, ecological efficiency, and current research situation at home and abroad, etc. and the results show that awngrass and silverreed possess many beneficial attributes being as energy plants because of their diverse ecological types, abundant wild resources, wide adaptability, strong resistance, high net energy output, excellent biomass quality, multiple utilization, good ecological value, and the suitability for marginal lands. Further study should focus on the germplasm collection, evaluation, and selection as well as planting and management techniques for their plantation on marginal lands.
