The brief for the rear side border
To create a classical English summer flowering herbaceous border with a modern twist of lots of drifts of different colours, mainly using plants such as agapanthus and salvia, possibly some drifts of Echinacea and later in the year Aster’s.
Normally with herbaceous perennial border, we would add some feature shrubs for structure, but I was thinking this time we would mainly stick to herbaceous perennials or perennial plants and just have a few feature shrubs such as some red and yellow cornus stem plants at the rear to add some interest in the winter plus a few helleborus at the front to provide some later winter flowering.

Style and example pictures
The style is very much a modern English or Scottish herbaceous border with some roses and clematis obelisk to gain height and add some colour from clematis and roses later in the year.
