Can anybody tell me what this is?, I originally thought Clematis but on looking at where flower comes from climber and bud opening towards bottom of photo i'm not sure now.
I know it's not a clem but I don't know what it is
Thank you nutcutlet at least you have confirmed it isn't a clematis.
It might be a mandevilla
I have just looked it up and I think your right, thank you very much.
I'm sure it is a Mandevilla, I have one.
