As Lindsay says, Mme Alfred is a great and vigorous climbing rose (mine's trained on a north fence and in heavy but free-draining soil and diesvery well).
I also have 2 raised flower beds along the same north fence and have snail-resilient hostas (sum and substance), ferns, hellebores, vincas, pulmonaria, heucheras in one (lime greens/purples/whites) and have made the other bed ericaceous, with an acer palmatum, camellia and more hostas and ferns in it.
Separately I have a north bed with loads of bulbs (cyclamen coums for spring, cyclamen hederifolium for autumn, snowdrops, lily of the valley, the odd bluebell) as well as some ground cover lamiums, and geranium phaeums plus other shade loving perennial geraniums.
Also have some lovely golden Hakonechloa, a Japanese grass which tumbles and is very tough.
I had never bought stuff for partial or full shade before I had this garden, but found it really easy once I'd found this amazing mail order site called: www.plantsforshade.co.uk - it's really well designed with easy to browse alphabetical categories, good info and photos. Worth spending some time reading and seeing what you like best.
Their delivery was excellent and all the plants I ordered were in great condition too.
Enjoy your shady patch!
