Help identifying apline plants

Hi does anyone know what the two plants at the bottom are? The blue flowers and the one to the right? Aren't they brilliant? I think they are from the alpine collection at RHS Garden Wisley but couldn't find anything more and have searched for ages online to find something like them - with no success. Any help appreciated

pics a bit small but could be lithodora diffusa
How pretty. Lovely stone wall too.
When was the image taken?
