NOT RECOMMENDED TO PLANT: INVASIVE TENDENCIES. Euonymus europaeus, or spindle tree, is not recommended to plant, due to its invasive tendencies. It is native to Europe and western Asia. It prefers well-drained sandy soil. All parts of the plant, including berries and flowers are toxic and should not be consumed. It has weedy tendencies, particularly in the Midwest United States, and can spread uncontrollably in garden settings. Consider planting Euonymus atropurpureus as an alternative.
