Is a norway maple a good tree to plant in Indiana?
Norway Maple can work here, with caveats. Still legal to sell and plant in Indiana as far as I can verify — the Terrestrial Plant Rule (312 IAC 18-3-25) banned 44 species effective April 2020 and Norway maple was deliberately excluded over nursery-industry impact, and the proposed twelve-species amendment that would add it has been stalled since 2021 by DNR rule recodification. Treat it as invasive in practice and keep it off recommendation lists, but do not tell customers it is banned; verify current rule status before publishing, because this is the one fact here most likely to change.
What you'd be signing up to clean up
Fall-ripening samaras with nearly horizontal 180-degree wings blanket gutters and beds in September and October, and they germinate readily — one tree will seed a fencerow, every mulch bed on the lot, and the neighbor's woodlot. Leaf drop is late, heavy and comes down all at once, typically after everything else has already been cleaned up, which is why it earns a second fall visit.
Where to keep it away from
Shallow, vigorous and wide-spreading — the reason turf will not hold underneath one even where the shade is manageable, and the reason its surface roots are the ones mowers scalp every season. It is the one species where mature trees are routinely found with severe stem girdling roots, so on any Norway maple call, excavate the trunk base and confirm there is a flare before you price anything else.
