Mayo - I recommend using whatever is most helpful to you. I use a letter and number system. Each plant has a unique code. If any of them become worthy of naming and registering, then I would keep the info about them from the original code and carry it over to the plant's registered name. Most people have a unique coding system that suits them best. Do what works for you and keep track of those codes BOTH on your computer and on paper somewhere. Nothing more frustrating that losing that info! Also be sure to use a marker of some sort to keep track of each plant. I also use mapping. I make a sketch of each garden bed and what daylily (code) is where in each garden bed.
