We are undertaking a landscapping project at our home fixing a multitude of issues. In trying to determine what plants to use I have become confused. I was reading past blog posts from the Renegade Gardener and in passing he mentioned dropping Barberry from his list of preferred plants because it has been determined to be invasive. But when I went to Gerten's I found it was being sold. I asked them how they can sell it if it is on the invasive species list. They didn't have an answer. I have since found it at multiple locations. Can you please clarify this for me? It had been on my plant list.
