I have had one for some years and cut it back every Autumn and it comes again the next year and is more spectacular. This year it has beautiful groups of small flowers and gives the rear of the garden a different look. My wife loves the colour. The one I have droops a lot if not kept watered. I have taken a cutting a year ago and left that in a pot and now that too is about 5 foot tall and doing well in a pot.
