The plant markers I use are called Perma-stake garden ID markers. Canadian made. I was able to find them last year with a Google search. If they don't show up for you, I'll look them up once I get home. Am presently in Vancouver with limited computer time. They are available through my local hosta nursery and last year cost me about 70 cents each. Since the Cdn $ is not at par with the US$; I guess they'd be about the same.
