Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.
Facts
Common velvet grass is native to Eurasia and northwest Africa, and introduced in both eastern and western North America. It is found in all New England states.
Habitat
Anthropogenic (man-made or disturbed habitats), meadows and fields
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.

common velvet grass. Nothoholcus lanatus (L.) Nash • CT, MA, ME, NH, RI, VT. Fields, roadsides, disturbed soil.
Native to North America?
No
Sometimes confused with
- Holcus mollis:
- lower internodes of stem glabrous and awn of upper lemma 3–5 mm long, bent but not hooked, well exserted beyond the glumes (vs. H. lanatus, with the lower internodes of stem softly villous and awn of upper lemma 1–2 mm long, hooked, scarcely, if at all, exserted from the glumes).
