I, too, use the plant list here in my profile. I just updated it yesterday after I got all of my new iris planted. I find that the notes in my plant list has the space I need. I mainly just make a notation as to the supplier's name and date received.
With my yard as small as it is, I don't have a huge number of different iris. So I just put labels in with them as I plant them rather than do mapping. I am now on my third type of garden label, and I can tell this third brand is much sturdier than the first two brands. I will try to fpfind the thread we had on garden labels and add a comment about this there.
