I have a thornless Banksia too and it flowers prolifically but not for long. Here it is under my window and over the front door.
On my deck rail I have rose, Crepuscule, which, in the 4 years since I planted it has never once been without flowers in every season. Mind you, we don't get snow here, just an occasional frost.
This photo was taken on 1st June - first day of Winter.
