Valeriana uliginosa — marsh valerian

Facts
Marsh valerian is common in much of its range, but rare in New England, with the greatest concentration in Maine, and one or two populations each in New Hampshire and Vermont. In New England, it inhabits northern white cedar (Thuja occidentalis) swamps and wooded fens. Canopy closure from natural succession, and changes to hydrology are probably the greatest threats to this species.
Habitat
Fens, swamps
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.
