Native and common statewide, and in central Indiana it is a woods-edge, fencerow and old-field species rather than a landscape tree — it colonizes clearings and abandoned ground, which is exactly why it shows up on the back edge of newer subdivisions built on former farm ground.
Nobody plants sassafras in central Indiana — it arrives on its own along the back fence, the treeline and the old pasture edge, then ends up on a quote once it has grown tall and skinny over a shed, a fence or the neighbor's drive. It is a brittle pioneer species that gets tall faster than it gets strong.
