Facts
This European native was introduced to North America as a garden plant, with hundreds of cultivars sold commercially for the past 200 years. For this reason, found individuals may vary somewhat from the description.
Habitat
Anthropogenic (man-made or disturbed habitats), cliffs, balds, or ledges, ridges or ledges
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.
