In a shady location, Azara microphylla 'Variegata' is a given. The variegation will help lighten/brighten up the area.

Have you thought about a variegated Pittosporum eugenioides?

Joe is right that Azara m. variegata will indeed brighten a shady spot. The only drawback is that I've found that it grows much more slowly than A. microphylla or A. dentata. If you don't mind the wait, it's a beautiful plant. If you're in a hurry, go with one of the other varieties.

Thanks, Joe and Wanda! I went to the nursery and brought home a specimen of A. microphylla variegata to see what it would look like along that shady wall, and tried to imagine what a whole wall of it would look like. It seemed like it would be a bit too busy, so I think (once the weather clears up) I will go with A. dentata or microphylla.

Joe, I hadn't considered any other pittosporum since it didn't seem like we'd have enough sun for any of them to do well. I also have the impression that variegated versions in general require more sun for best color--true?
