Facts
Rand's goldenrod is named for its discoverer, Edward Lothrup Rand (1859-1924), a Boston lawyer and amateur botanist who published a flora of Mount Desert Island, Maine.
Habitat
Cliffs, balds, or ledges, mountain summits and plateaus, ridges or ledges, shores of rivers or lakes
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.
