I'm thinking the UV rays will fade the postcards pretty quickly.

Are you planning to decoupage the postcards/pictures of roses onto some hard surface an then put that into your garden? I don't think you will be able to find postcards of all your roses, but you can probably print pictures of them off onto cardstock and then decoupage onto something, if that's what you're meaning...?

I doubt your idea would last through even one season ... though it would be really cool. The only things that I have found that really last in the garden are:

1. The engraved labels that I get from AAA Quality Engravers
2. Paint pen on galvanized tags ... NOT Sharpie marker.
3. Using an engraver to etch the letters into a galvanized tag (though I can't see these very well by the end of the year)
4. Though I don't have them in my garden, I know the Harland labels hold up really well.

I have been using a label maker (byt Brothers, I think) and stainless steel markers (from Kinkaid). So far I like this way best.

I agree, UV fade is an issue. I'm an old vintage postcards dealer. Fade of these collectibles would be a shame. Why not use a UV protection similar to what windows use? There's got to be a UV protection film out there that could be used as a cover. Also, if the postcards are scanned, it wouldn't be hard to replace the rose images each year with fresh ones that aren't faded. This would also protect the original postcard. Roses are sooo beautiful. They're always a favorite of mine to list. Enjoy the images!

Color copies don't fade so fast.
