Oh gosh at one time I grew over 1100 registered cultivars. Don't have time to keep separate sheets on each cultivar. They're lucky to get one line. The notes part is where I keep notes about performance, any negative or positive attributes that are noticed during a bloom season, rebloom, etc. I know where every cultivar is located ( esp. now that garden size is down to about 400) so don't need to make notes on sun, etc. Just don't have the time because during bloom season I'm out taking pictures, hybridizing, or going off on weekends to judge shows, etc. Many notes are made in the off season or right after bloom season is over , If something had a sub-par bloom season, I'll either make a note to remove it/ sell or give away the following spring OR will make a note that this one needs moving, this one needs to be re-evaluated the next year, etc. Since I've been doing this for a long time, I'm mostly dealing with established clumps except for the handful of new ones each season. Also note here when a clump needs dividing. Hope this helps.
