Native and present statewide but genuinely less common than sugar maple, favoring moist bottomland and calcareous upland sites — which describes a great deal of central Indiana. Purdue treats it as a distinct Indiana tree and publishes a dedicated Norway/sugar/black identification comparison, which is a good sign of how often the three get confused in the field.
Effectively a sugar maple variant — often classified as Acer saccharum ssp. nigrum — told apart by darker, droopier, mostly three-lobed leaves and small leafy stipules at the base of the leaf stem. It matters practically because it handles heavy, moist clay better than true sugar maple, yet it is routinely sold, mapped and invoiced as sugar maple, so what a homeowner believes they own often is not what is in the yard.
