It is funny that you love a same thing that drives me nuts. Knowing exactly what Coleus I had last year, for example, is like a hex on finding the same one again. LOL! How interesting. Definitely something to talk about.
My planning rarely goes beyond clearing as many weeds as possible from where I will want to put the plants I'll find when I go shopping, and wondering where to put this or that new little plant, now that I've propagated more of it.
