Mahonia aquifolium, or Oregon grape holly, is an American native that grows in the western U.S.. It is not considered an invasive in Ohio. I did find some reference that considered it a threat in some areas of the Wisconsin.

On the other hand, Mahonia bealei, or leatherleaf mahonia, is a Chinese import that has naturalized throughout the southeastern states and is considered an invasive. It is only zone hardy to zone 7 and also is not considered a problem in Ohio.

Overall, I would say enjoy this beautiful, deer resistant shrub.
