Additional Notes

Comments

Euonymus alatus is native to eastern Asia. It is a popular ornamental, prized for its bright red to reddish-purple fall foliage and colorful, interesting fruits. Unfortunately, birds consume the fruits and disperse the seeds. It is widely naturalized in the eastern United States and was first documented in the wild in Kansas in 1980. It appears to be spreading rapidly in woodlands in eastern Kansas and should be expected in additional counties.
