Q.Why Aren’t You Specifying STERILE Barberry Plants When You Tout How Great They Are?.
You HAVE to be aware of the havoc these invasives cause. It is so sad that both plant vendors and purported Gardening Experts don’t deal with this problem.

In order to be fair and include gardening information for everyone, it is also necessary to provide information on any plants of interest. All plants have the capability to become invasive given the proper environment, yet all plants are not invasive everywhere.
It would be unfair to those that live in an area (such as mine) where these shrubs are not invasive to not include information for those who wish to grow them.
It is up to each individual to garden, responsibly, and research what is sustainable in the area. Should the answer not present itself clearly, then one can contact local extension services. The local extension services in an area will be able to tell you what plants are blacklisted in an area, or what may grow well in your area.
Here is a link to help you find the closest extension service to you, so that you may request information about plants before you plant them in your area:

Contacting them before planting will help prevent you from planting any other invasive species in your area, again.
