Does anyone have a source for permanent plant labels? Our garden club is looking into purchasing engraved or etched labels for the plants in our gardens around town. We're not looking for labels to write on but ones which we can order with the information (common name, latin name, etc.) already engraved into the surface. We're afraid printed labels will fade in the sun unless, perhaps, they are anodized aluminum.

There are lots of sources for blank labels but we're looking for something more permanent.

Thanks!
