Facts
Pod-grass inhabits bogs and fens across much of northern North America, Europe and Asia. It is protected in some New England states. Its long, rope-like rhizomes are sometimes found mixed in with peat in bags of commercial peatmoss.
Habitat
Bogs, fens
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.
