Thanks for the pics SGL - I'm afraid I don't know what the bush is - some form of conifer obviously.
I can see that would work at the back of a border - unfortunately it's probably a bit large for my spot. Think I shall be checking out various forms of laurel and euonymous - bit boring I know but I can keep it nice and tidy and shape it properly which is going to be quite important.
Thinking about your spot - I have a rose called Roserie de l'Hay. It's a rugosa rosa so tough as old boots, disease resistant and has heavily scented lovely deep pink / burgundy flowers. It will make a dense shrub over 2m high & is described by David Austin as one of the very best rugosas.
Mine was smothered in blooms in June / July. It was deadheaded regularly and is ready for a second show now. I expect it to flower on & off through the rest of the summer. The perfume fills the garden on a warm summer evening. It also looks good when it is just foliage - but I'm sure it would stand a clematis growing through it for additional flowers.
Hope you find something you like
