I make beautiful scrapbooks of each year's iris bloom season, a pictorial recording of what bloomed that year. I also have some maps and keep a journal by date of what blooms each day throughout the season.
I had an Excel spreadsheet for the info and what bloomed and how many of each bloomed but inserting newly acquired irises in, somehow it did not insert across the whole line so everything got messed up and I gave up! Someday I will straighten it out, hopefully.
