Native at least in the southern half of the Lower Peninsula, and apparently northward on some river banks and floodplains as far as Baraga and Houghton Cos. of the western Upper Peninsula. Widely cultivated and readily escaping throughout the state; a weed in some places. Swamps, shores, and banks; spreading aggressively so that seedlings and small (to large) trees are common along fencerows, sidewalks, railroads, ditches, and disturbed places generally; invading old fields and open forests.
The leaflets are usually 3–5, rarely 7. Small plants, such as seedlings, with 3 leaflets can easily be confused with poison-ivy until one notices that the leaves are opposite.
Vigorous first year shoots on at least some individuals have a striking glaucous 'bloom' entering winter.
