Copper Plant Hang Tags are my favorites for labeling shrubs. They don't shine like a beacon and they age with that beautiful verdigris patina. These come 12 to a package. They have a 4" writing surface and you can use a black wax pencil on them (that won't wear off or fade) OR you can use a ball point pin or just a nail to emboss the writing for permanent identification. They also make really classy gift tags.
