So here's my question: is gardening under a silver maple likely to be so difficult in the long run that I should just let the artemisia take over and serve as a ground cover, or should I start attacking it and continue my efforts with my preferred plants? One of my problems is determining if it will just be ugly anyway. It got too tall and leggy in one container in which I tried it, so if it is going to make a huge bed of 2-foot tall limelight stuff, I don't think I want it. I had intended it as an accent against the green of other things, never realizing it would spread like this. Plus I don't know if it seeds and will get into other nearby beds.

It may be almost impossible to get out anyway, but if I'm going to do it, now would be the time to start. This is one of those questions whose answer I think I already know.... but chime in anyway!
