So the right hedge is a Rhododendron. So you may have Acidic soil. That is useful as it opens up a bit of choice for plants like Tropaeolum Speciosum - can scramble over bushes and around the ground.
Your left border could have Ajuga Caitlin Giant, lovely glossy base leaves and most striking blue flowers. Luzula Nivea, fine strappy green leaves and white flowerheads in summer and base of Asarum Europaeum, the wild ginger. Rounded glossy deep green leaves to cover the soil.
Against dark walls of hedges, Hesperis Matronalis 'Alba' will be the repeated accent plant that anchors your whole garden together. Other interest to dot plant around the back and if you have a raised planter either running along the right curve of the lawn or to the front of the lawn, Salvia Nemorosa Caradona, Salvia Pratensis, Knautia Macedonica, Scabious Columbaria, Lychnis Coronaria 'Alba' and Achillea Terracotta, Hemerocallis, Cranesbills - so many varieties, just take a look to find your right one for height and flower colour. They are also the best plants for leaf form when there will be dips and gaps in colour interest. I could go on and on as it goes with herbaceous planting schemes.
I find myself saying the same thing when advising on narrow or smaller borders. Scale is important. The ideas are usually the same, but it's just the scale. Block planting is good if you have the space, but very often we don't or we want too many plants in a confined space. Think about planting young plants into diagonal strips. You will hopefully get a more naturalistic look on a smaller scale. Ground covers near the edge of lawns makes a nice formal feel and the more 'wild' look is held back by this low mound.
Sometimes, it creates a pleasing contrast of control and natural which I think is best usage in a medium to small size area. Leaves of size, shape and surfaces are also things to think about when choosing plants.
The Salvias are a risk on your soil, but if you have worked in lots of grit and compost, and continue to do so every year, there will be loads of plants to add on your list.
