Most of my record keeping is on the seedlings as you can get into a mess in a hurry there if you don't keep records on them. Each cross gets an alphanumeric, like E129, to designate the cross. That information is stored in a notebook. If seedlings are numbered from a cross they get added, separated by a dash, so E129-1 would be the first seedling from that cross. A description of that seedling goes into the notebook. (That one happens to be in production BTW, a big blue/ pink combination.) If the plant is one I'm naming I also take further notes on the flowers.
I do use aluminum markers from Paw Paw that even with #2 pencil markings keep their integrity through many years. I do get some movememt of markers from animals of all types and that generally involves re-marking the plants.
In the garden I tend to cluster the ones from given sources together so that all the plants from Erwin are in one area and all from Howard are in another. However my yard is more and more dominated by my own things, either ones I've named or a seedling I'm either considering for introduction or using for breeding. If I were a commercial dealer I would probably keep more detailed records of the cultivars from others but the seedlings are my thrust.
