Kyla, if it was me, I'd find a different thing to use for the tags. The pen/pencil may not fade, but the wood will probably rot from the water. I use vinyl miniblind slats, cut into the shape of a tag, and write on them with pencil. They have never faded. I used popsicle sticks one year, and the wood rotted below the dirt line. These were on non-daylily seeds, so no big deal, but it was a good lesson learned!
Your gardens are very nice!
