Going down the line

I love the way you've used the 'pinky' coloured edging stones at the front.
Would they normally be used at 90° and 'set' in the ground, for a cobbled effect ?
I love the idea of using materials as they shouldn't really be, in a non-conformist way, unconventional. It can really spark off the 'effect' sometimes, especially in gardens.

Your Coleus plants are beautiful with the contrast of the Hostas, do the Coleus survive the winter or are they annuals?
