Even though it is increasingly popular to have vibrant reds and oranges in your planting scheme, take a look at these photos.
The softest of pink Roses, with interesting companion planting.
Blue and purple compliment the pink blush of the Rose with Phlox, Campanula, Forget-Me-Not and Irises.
Plus the white of Digitalis and Aquilgea with the frothy white Ammi Majus freshen clean up the palette.
Then to round the colour scheme off there is pink Persicaria bistorta Superba and Thalictrum, all floating on a body of green foliage.
This is definitely a mid summer garden. You could have Tulips and Purple Sensation Alliums for the earlier months and then move on into late Summer with Dahlias and Asters.
