Not native but naturalized and found throughout Indiana, planted historically for fence rows and fence posts — Purdue documents this history directly. In central Indiana it usually turns up as a surviving hedgerow line at the back of a property or along a former field boundary, which means shared-ownership and property-line questions come up more often than with other species.
Not native to Indiana but planted across the state as living fence before barbed wire and again for erosion control in the 1930s, so nearly every one in central Indiana is a hedgerow relic that a subdivision later grew around. It lands on a quote almost never for structural reasons — it is the softball-sized fruit and the thorns that generate the call.
