Background

Winged euonymus is a deciduous shrub introduced to North America as a horticultural species from northeastern Asia. Since its introduction to North America in the 1860’s it has been used in landscaping, along roadsides as hedges and in foundation plantings. The bright foliage of the species makes it a popular ornamental plant, contributing to its spread across the continent. It is also commonly known as “burning bush” because of its bright red foliage.

The winged euonymus is able to grow in a variety of soil types and typically found in open woods, disturbed lands and floodplains. This species behaves well in urban landscapes, but must be maintained, and should not be planted near woodlands because it can escape cultivation and invade the forest understory.

Range
