Vulpia myuros grows in well-drained, sandy soils and disturbed sites. It is native to Europe and North Africa. Vulpia myuros f. megalura (Nutt.) Stace & R. Cotton differs from Vulpia myuros (L.) C.C. Gmel. f. myuros in having ciliate lemma margins. It was once thought to be native to North America, but it occurs throughout the European and North African range of f. myuros, even in undisturbed areas.
