Would less invasive wisteria be okay for this arbour?
We have a sort of lovely arbour in our back garden and I'd like to make more of a feature of it. Initially I'd like to paint it a soft green (find the current reddy brown stain a bit harsh) and then grow something up it. I had thought of a shrub type Wisteria as a slower grower and because I love the colour (this sort: http://m.ebay.co.uk/itm/371877536078?_mwBanner=1) but am now wondering is this is naive and whether being a wisteria it's a bad idea.
I love rambling and climbing roses as an alternative but I don't have much time for maintenance. Also the back garden is not south facing but I'd love to get some growth under the arbour roof to screen the cheap looking plastic roof sheets. I figure the wisteria will be vigorous enough to do this where as a rose probably wouldn't. However I have no real idea what I am talking about so would appreciate your more experienced views.
The arbour is about 4m by 4m and seems sturdily constructed.
