It looks kind of like a holly of some sort, but the leaves are more broad than any holly I've seen! Also, if you know what it is, just what are those berries going to do? Flower? Change color? Stain my clothes?
Okay, okay! After enough of you have gushed over the beautiful mahonia, I'm not sure I'm just going to kill it off. Maybe there's a corner of the yard that could use a new plant. If anyone is in the Smyrna, Powder Springs, Marietta area and would like it for themselves, let me know. Also good to know: when is the best time for a transplant??? Keep in mind that digging this out will stress the mahonia and the intertwined azelia that I'm trying to keep!!!!
Sometimes you just have to choose between damaging one desirable plant over another less desirable one. Even though many of us love Mahonia....its not a rare plant and would not be a great loss to just cut it down. If the azalea is the plant you want most, then protect it. Or...you can very carefully cut it out below the soil line...getting a few roots and pot it up until it can be given to someone or safely transplanted with healthy roots. Same with your Rosemary, Caitlin.
