Karen, I'm sure that they think it is a gnome or elf cemetery, if they don't realize that they are plant markers.
The only time my markers show up well are during winter, when all the daylilies are asleep. Otherwise, I have to search for them when I need the name. I push them almost all the way to the ground, and the foliage covers them for the most part. So, I never notice them really. Luckily you can't see my garden from the road, or everyone here would think I'm crazy. Or, they would think that I've got a gnome or elf cemetery.
