I then put the letter indicating the cross, then a number when the plant bloomed. I originally left it at that. Then I saw a friend who indicated the type of plant, for example 79S7C. We still grow that SDB seedling of his. Since I started just working with SDBs, but then added other classes. The SDBs were left as I started, but I added D (for dwarf), I for intermediate,) M (for MTB ) ( B (for border). I do not do Tall bearded as many people do Those & I like the medians best. John sort of frowns on my BBs but if I ask him to judge a BB seedling, he will do so.
As I said I usually give the plant a number, but with my most mature MTB cross I had only kept 4 plants so indicated them by color (red, rust, purple & violet.) I will see if I can get the photos to come up next.
