''Festuca gigantea'', or giant fescue, is a plant species in the Poaceae (grass family). Because this and other members of ''Festuca'' subgenus ''Schedonorus'' have more in common morphologically with members of the genus ''Lolium'' than with ''Festuca'' and often produce fertile hybrids with other ''Lolium'' species, ''Festuca gigantea'' has been recently published as ''Lolium giganteum'' and then as ''Schedonorus giganteus'' .〔(Stephen J. Darbyshire, ''Schedonorus'' treatment in ''Grass Manual on the Web'' (updated 2009) )〕〔(R.J.Soreng, et. al. (2012) A World-Wide Phylogenic Classification of Poaecea (Gramineae): căo (草), capim, çayır, çimen, darbha, ghaas, ghas, gish, gramas, graminius, gräser, grasses, gyokh, he-ben-ke, hullu, kasa, kusa, nyasi, pastos, pillu, pullu, zlaki, etc. (rev. 18 Oct 2012) ) (includes ''Schedonorus'' in ''Lolium'' in subtrib. Loliinae)〕 Sources vary as to which placement is more acceptable.〔(''Schedonorus giganteus'' (L.) Holub, USDA-NRCS ''PLANTS'' Database, 2013-02-27 )〕〔(''Festuca gigantea'' (L.) Vill., USDA-ARS ''Germplasm Resources Information Network'' (GRIN), 2013-02-27 )〕〔(''Schedonorus giganteus'' (L.)

Missouri Botanical Garden. 2013-02-27 )〕 ==Description==
This grass can grow up to 2 metres. It is loosely tufted, hairless, and has auricles. It has dark read leaf nodes, and there are six 8-13 mm long spikelets. Festuca Gigantea have long awns, forming flowers during the July to August period. It is a common plant found especially on heavy, neutral and calcerous soils, in woodland, hedge banks and shady places.〔page 408, Wild Flowers of Britain and Ireland, by Marjorie Blamey, Richard Fitter, Alastair Fitter, published 2003, ISBN 0-7136-5944-0〕 It is said to grow best in moist woods. Festuca gigantea produces fertile hybrids with perennial ryegrass and italian ryegrass,〔page 46, Collins Pocket Guide Grasses Sedeges Rushes and Ferns of Britain and Northern Europe, by R Fitter, A Fitter, A Farrer, published 1995, ISBN 0-00-219136-9〕 hence the confusion with its phylogeny and identification.
