''Trisetum flavescens'', golden oat grass or yellow oat grass, is a species of grass in the Poaceae family. It is native to Europe, Asia, and North Africa. It can be found elsewhere, such as sections of North America, where it was introduced as a rangeland grass for grazing.〔(Grass Manual Treatment )〕 It now exists in the wild as a common weed. ==Description== ''Trisetum flavescens'' is a perennial bunchgrass growing in clumps up to tall, and known to exceed at times. The inflorescence is a narrow panicle which is greenish yellow to purple when new and ages to bright golden yellow.〔〔Dixon, J. M. (1995). (''Trisetum flavescens'' (L.) Beauv. (''T. pratense'' Pers., ''Avena flavescens'' L.) ) ''Journal of Ecology'' 83:5 895-909.〕 The grass is susceptible to yellow oat grass mosaic virus (YOgMV), a virus of genus ''Tritimovirus''.〔Hassan, M., et al.
