I've never formally mapped where things are, but I do track which bed specific plants are in. With that basic information, I can generally track things as they come up. Not always, I often have a mystery plant or two, but then I have the treasure hunt fun of trying to ID it. I previously kept a master Word document, with all of the relevant plant information (common name, latin name, location, source, needs) plus a bloom photo, but that file got too large (dang Microsoft waits until the file exceeds its limit to tell you it can no longer be opened...go figure...) so I am now transferring that data into the ATP List feature. Under my personal comments in the ATP List, I can then note which bed(s) the plant can be found in and the year it was planted along with specific cultivation notes and whatever other information I might want to keep track of. I like that my personal notes only show up in my own List and not as a general plant comment (e.g., I doubt the membership cares that I find primroses to be squatty little plants that I have an aversion to and should quit putting them in my grocery cart...)
