I also use a spreadsheet, but a little differently. Each spring, I take a folding chair outside and write down each pot, the pot size, shape & contents, and name of the plants, Also include where it came from, a count of hens, a count of chicks, a comment if needed and living or dying. I add new aquisitons to this list all summer long. As I'm creating the list, I type it into an Excel spreadsheet, so I have a spreadsheet for each spring of my plant collections.
For those of you that are comfortable with Excel, it is worthwhile to learn MS Access, the database that comes with most of the MS Office packages. Access can take the data from Excel and automatically create a database data file from the data. The neat thing about Access is that you can define reports to run against the data. So if you have a column for plant maximum size, your could generate a report that would list all of the large semps. You could also use that field to generate a report for all of the small semps or whatever size you wanted. You can mix and/match the different categories that you choose to create. So you could get a report that says which of your semps turn purple and stay small, for example.
Access is pretty easy to use, but if you have not worked with that program or other database programs, then it takes a little effort to get going with it. It's not because its hard, but because it can basically do whatever you can imagine doing with it, which means there are lots of possiblities to sort out.
