Facts
Sheep fescue is an exotic turfgrass that was once widely planted because of its drought-tolerance and ability to grow in difficult conditions due to its association with mycorrhizae. Its delicate, bluish-green leaves, arise from dense tufts, and the 'glauca' cultivar is an attractive garden plant. Sheep fescue is a host plant for several species of butterfly in Europe and north Africa; its relationships with North American butterflies and moths are less well known.
Habitat
Anthropogenic (man-made or disturbed habitats)
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

sheep fescue. CT, MA, ME, NH, RI, VT. Lawns, fields, roadsides, seeded areas. Festuca ovina was used introduced as a turf grass, but it not widely used anymore.
Native to North America?
No
Sometimes confused with
- Festuca filiformis:
- lemmas awnless or with a tiny mucro up to 0.4 mm long and leaf blades of vegetative shoots with 1 rib (vs. F. ovina, with lemmas with awns 0.5-2.5 mm long and leaf blades of vegetative shoots with 1-3 obscure ribs).
- Festuca trachyphylla:
- anthers 2.3-3.4 mm long and leaf blades mostly 0.8-1.2 mm wide, with 4-7 ribs (vs. F. ovina, with anthers mostly 2-2.5 mm long and leaf blades mostly 0.3-0.7 mm wide, with 1-3 obscure ribs).
