Dumb question about new/old wood
I am a newbie. Sorry to ask something so dumb, but I don't understand clematis.
I just discovered I have an Elsa Spath, which is group 2. Group 2 bloom on old wood and should be pruned lightly. What exactly is " old wood" ?
The flowers on my plant are (at the very tip of the growing vines, which makes it be "the newest" wood.... I really don't understand....
I also have what's supposed to be a Sunset clematis, also group two, blooming on old wood. She didn't do an inch of growth for two month in the ground, and now it started suddenly to grow two new vines, and each has a tiny bloom at the very end of the tip.
so can somebody explain me please how is the thing with " blooming on old wood", when my clems ( type 2) seem to want to bloom on the new wood? What (age) makes the wood old?
