Native to southern Indiana and fully hardy in central Indiana, which the 2023 USDA map moved to zone 6a-6b, so it is a legitimate long-term shade tree here rather than a marginal one. Fruitless cultivars like 'Rotundiloba' exist and are the right answer for a replant, but essentially none of the mature sweetgums already standing in central Indiana yards are that cultivar.
Nobody calls about sweetgum because it is dangerous — they call about the gumballs. It is a strong, long-lived, ice-tolerant shade tree that happens to carpet the yard with spiked seed balls every winter, and a lot of sweetgum work starts as "can you stop the balls" before it ever becomes a removal quote.
