@Julie, I use the AAA markers in my garden and for the most part, highly recommend them, too. (My garden has never been on a daylily tour and never will be, but it has been visited by a garden club tour, and any and all visitors who come to the garden ask where they can get the same labels.)
The downside of the AAA labels is that the labels can be snapped off the stake - by people or critters in the garden. I have lost more than a few labels that way (I could never find them under the mulch, and darkly suspect them of having been raked away by my sometimes helpers). Sometimes also the plastic grip part on the label breaks, such that the label then can't clamp onto the stake.
I don't know what the fix for these problems is... possibly to superglue the label onto the stake?
(But then you can't reuse the stake, when you decide to get rid of the plant.)
This reminds me, though, that I need to put in another AAA order...
