Happy summer everyone! Difficult spring here, but things have settled down somewhat for now. How are all your gardens doing?

I need suggestions for a shrub clematis. Colour is optional, need something that will take a bit of shade, but good light in a north facing bed. Do any of you have a favourite(s)?

Thanks

zone 5 currently, but they tell me this may change to a 6 in the next few years.
