Dianthus and carnation border

[Rosemaryandlavender1]

Hello all!
I have in the past received great advice on this board. This year I have created a small cottage style flower bed on the right of the rosemary bush and planted a hydrangea in the shade on the left. I purchased some dianthus and carnation over the weekend. I was thinking of attempting to merge both sides with a little border of these. Does it look ok? They do get sun throughout the day.

Something like this

On the right hand there's a rose with delphiniums salvias and bowles mauve. Its a pink and purple sort of colour palette with a little bit of white.

There's a hydrangea on the left that hasn't bloomed yet but I'm not working more on that side yet until I see how it does throughout summer. It's all just been planted this year which is why it hasn't fully filled out yet.
