So right, greene. Common names vary a lot, especially in different parts of the world. I get teased for being 'snooty' when I use botanical names, though. My daughter says 'Oh, Mum don't be such a plant snob'.
May I add that I've tried a few label makers for plant labels, and none of them hold up very long in the outdoor environment. It's really frustrating to find your lovely labels with the printing faded completely. You should try a few out in the sunshine and see how they hold up before you go labeling your whole yard.
Who's got a favorite labeling method? I'm currently using cut up strips of black plastic nursery pots, and a silver Sharpie paint pen to write on them. They're cheap and they last (as long as the squirrels or birds don't steal them).
