Mine flowered for the first time last year. I really did need to cut it back as it was getting so tall it was blocking my view from the window. I'm afraid it was an impulse buy a few years ago and was planted with a view to moving it to a better position when I cleared a new border. Unfortunatly it took me so long as I had an op on my foot that it never did get moved. Must really stop these impulse buys !!
