Shape
Lobed (mitten-shaped and deeply lobed with 3-5 distinct lobes)

Venation
Palmate venation with prominent veins radiating from the base, featuring a clear net-like reticulate secondary venation network.
Key Features
Highly variable leaf shape on the same branch (some unlobed and cordate, others deeply mitten-shaped or multi-lobed), milky sap in the twigs and petioles, and coarsely toothed margins.
Description
The tree features rough, furrowed bark, milky sap, and produces inconspicuous green flowers followed by blackberry-like aggregate fruits that ripen from white to pinkish-red and finally dark purple.

Thrives in disturbed areas, forest edges, urban environments, roadsides, and abandoned lots. Prefers full sun to partial shade and adaptable to a wide range of well-drained soils.
Native Range
Native to northern and eastern China, but now widely naturalized and invasive across much of North America, Europe, and parts of Asia.
