"Blooms on Old Wood"

If you are ever reading about pruning you will often come across lists of plants that divide them into two catagories, those that flower on old wood and those that flower on this years growth.
I have been loving these Quince branches (Cheanomales) in my office for the last 10 days. Having them here in front of me leads to this contant study and reflection. Just a bit ago, I was looking at the blooms and how they are all located nearest the trunk or the main stem and the tips of the branches are bare of blossoms.


It is just a very quick glimse at or an example of a plant that "Blooms on old wood." In fact, it is possible here, that it not only blooms on old wood, but wood that is older than two or three seasons.
Further, I suppose that to recognize this you would have to understand that plants grow outward from the buds located at the tips of the branches and not outward from the stems.
And, of course, here, when I say "plants," I mean "woody shrubs," because not all plants grow this way - like grasses.
