DISTRIBUTION AND OCCURRENCE
SPECIES: Vulpia octoflora | Sixweeks Fescue 



GENERAL DISTRIBUTION : 
Sixweeks fescue occurs from British Columbia and Ontario southward
throughout the United States [4,11].  Vulpia octoflora var. glauca grows
mainly in the eastern and central United States and is occasionally
found in the southern portion of the western states [4].  Vulpia
octoflora var.  hirtella occurs mostly in the southwestern United States
and in Mexico but occasionally reaches as far north as Washington and
Montana [4,14,18].  Vulpia octoflora var. octoflora is distributed from
southern Canada to Mexico [4,14] but occurs primarily in the
southeastern United States [18].  Vulpia octoflora var. tenella, a more
northerly variety, grows from British Columbia to Maine and southward to
Georgia and Colorado [8].  Fernald [8] reported that Vulpis octoflora
var. aristulata grows mainly in the South, from Florida and Texas
northward to southern New Jersey.

HABITAT TYPES AND PLANT COMMUNITIES : 
Sixweeks fescue is locally common in sagebrush deserts and
pinyon-juniper woodlands [4].  This weedy annual is at least a minor
constituent of many native and introduced bunchgrass associations.
Plants commonly associated with sixweeks fescue in plains grassland
communities include blue grama, plains pricklypear (Opuntia
polyacantha), scarlet globemallow (Sphaeralcea coccinea), red threeawn
(Aristida longiseta), sand dropseed (Sporobolus cryptandrus), woody
buckwheat (Eriogonum effusum), and sun sedge (Carex heliophylla) [14].
