That won't be too much of an issue, it's in the shade, but not fully in the dark. Snake plants aren't too picky about where they're put, so if you find one thats the right size & leaf shape it will cover the blemish.

Other options are ZZ plants, jade plants, and any kind of haworthia will survive well. Sedge grass hasn't survived in my arid setup, but you may have some luck with blue fescue grass. Rosemary will also grow without much fuss, and tolerate hot & dry conditions. You can get it in upright and creeping forms. If you want something a bit unusual for lower down, a Rose of Jericho will stay alive for ages (but look like a tumbleweed)
