White mulberry (males or fruitless cultivars)

Leaves of white mulberry.

White mulberry can be invasive; look for males or fruitless cultivars. It is an aggressive, often weedy tree native to China. It was originally imported for the silkworm industry, but has since naturalized throughout North America in fencerows, abandoned fields and urban areas.

This plant has some cultivated varieties. Go to list of cultivars.

More Information: 

Tree & Plant Care

Fairly tolerant of alkaline soils.
This can be a fairly high maintenance tree due to a tendency to self-seed.

Disease, pests, and problems

A variety of pests are possible including leaf spots, witches brooms, cankers, powdery mildew, spider mites and scale insects.

Disease, pest, and problem resistance

Tolerant of black walnut toxicity.

Native geographic location and habitat

Native to China.

Bark color and texture 

On young trees, bark is fairly smooth, but with visible lenticels.  On older trees, the bark becomes deeply fissured and reveals the inner bark.

Leaf or needle arrangement, size, shape, and texture

Simple, alternate leaves vary in shape.  Some may be egg-shaped, while others are distinctly lobed (3 to 5 lobed).  Leaf margins are serrate.
Leaves are dark green in summer, turning yellow in fall (not always consistently good fall color).

Flower arrangement, shape, and size

Male and female flowers may be on separate trees or on the same tree.

Fruit, cone, nut, and seed descriptions

The fruit is a 1 1/2 inch long cluster of tiny berry-like structures; ripe fruit range from almost white to dark purple.
