For a self clinger Hydrangea petiolaris is the go-to plant; would give it some thought re maintenance if it's a house wall, but definitely ideal for a garden wall. Or there's Pileostegia but I have heard it is quite slow.
If you can give some support, I'm finding Trachelospermum happy on a north facing fence (happier than the one I've got that's south facing). I've got Rosa Alfred Carriere which is apparently THE rose for a north facing wall - but I only just planted it.
It's hard to beat clematis, but you will need some supports for them - wires and vine eyes etc. Dozens of varieties are happy in shade. The climbing hydrangeas are stunning, but they get big, so the wall needs to be appropriate, or you don't get the best from them.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...

Also Honeysuckle such as Lonicera periclymenum 'Serotina
