Description
The White Mulberry is a fast-growing, deciduous tree or large shrub reaching heights of 30 to 50 feet. It features a rounded, dense crown, rough grayish-brown bark with shallow fissures, and milky sap in the twigs. The leaves are remarkably variable on the same tree, ranging from unlobed, heart-shaped blades to deeply lobed forms.
Habitat
Found in disturbed areas, forest edges, urban environments, roadsides, and open woodlands. Thrives in full sun to partial shade and adapts well to various soil types, preferring moist, well-draining soils.
Native Range
Native to temperate Asia, particularly China. Widely introduced, naturalized, and often considered invasive throughout North America, Europe, and parts of South America.
