Lovely happy-making sunflowers.
Ref plant supports - the best solution is woven hazel or willow 'frames', made anew every spring as the perennials first appear, and composted with the dead plant material every winter. Kew do this, and many historic gardens. Lots of places do courses in how to make them, and from what I've heard it's pretty simple, so those with a crafty bent could probably figure it out by looking at them.
It should be pointed out here that I have never done a course nor attempted them, though one day I will.
Excellent rhubarb idea. I may steal that.
Loving the musical talk. I love singing, despite being completely off key. The local toddler group that I lead doesn't seem to mind, fortunately. 
I begged and begged my mother to allow me to learn a musical instrument when I was a child, but I was always told it was too much money and I'd get bored so they weren't forking out. 
My dcs will have enforced music lessons as a result.
