It is easy to see why people would want to plant winged burning bush (Euonymus alatus) in their yards. It is a beautiful flowering shrub for your landscape, simple to grow, and is also low maintenance. But it is an invasive species that spreads easily and has overgrown some forest areas on the U.S. East Coast. Winged burning bush (sometimes just "burning bush") is not poisonous nor does it have thorns, but the danger it presents to native species is certain.
