I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
The peppermint is aggressive and will be fine if you keep the area moist. In dry conditions it won't look good at all. I might also consider other options such as a short growing ornamental grass if you don't feel that creates too much of a jungle for things to hide in.
Thanks for the question. Best wishes for a wonderful gardening year in 2007. Please stop in again soon!
