Wisteria

Years ago we lived outside New York City. We rented part of a house that had wisteria growing on the side. Every summer, the owner would come out and hack away at the vines. At first, I thought he was crazy with the amount he would prune. But, he knew what he was doing, and his wisteria bloomed every year.

I've followed his example with the wisteria we have in our yard. I prune it after it flowers and again in mid-summer. And, it blooms every year.
