Description

Deciduous tree that reaches to 25 ft. in height and 15 – 28 ft.in width. Grayish brown bark, smooth with darker striation furrows with age. Typically multi-stemmed with a spreading umbrella-shaped crown. Opposite, simple leaves with 3 lobes. Pale yellow or cream, tall flower clusters appear in early spring.

Habitat

Location in Nebraska

Found in a few counties in Eastern Nebraska.

Pathway of Introduction and Spread

Commonly planted in landscaping due to its hardiness and fall coloring, but has, however, escaped cultivation and spreads into natural areas.

Impacts

Considered invasive species in the Eastern U.S.; can displace native shrubs and under story trees in open forests, and shades out native species in prairie habitats.
