A harmonious Dorset rose garden designed by Isabel and Julian Bannerman

Having turned a farmyard into a walled garden at Upper Sydling House in Dorset, Susanne Cooper commissioned Isabel and Julian Bannerman to help her to create the beautifully structured series of harmonious spaces that showcase more of her beloved roses and frame views of the meadows beyond

Susanne has always been passionate about roses and has over 120 different varieties and 400 individual plants, which inhabit almost every corner of this extravagantly planted garden. ‘When I began gardening, I quickly became addicted,’ she admits. ‘I visited gardens like Mottisfont and Sissinghurst, and read lots of books. I was constantly thinking about colours and how they sit together, but Isabel always told me not to worry about colours so much.’

Most of the roses planted initially were repeat-flowering English roses from David Austin, but as the planting has matured, Susanne has also fallen in love with old-fashioned roses like ‘Cardinal de Richelieu’ and ‘William Lobb’, which flower only once. She has a ruthless approach to experimen-tation. ‘If a rose isn’t healthy here, it comes out and I try something else.’ A more recent addition is ‘Royal Jubilee’, a shrub rose that has deep pink, ball-shaped blooms through the summer. Inevitably, her roses need an intensive maintenance programme in the growing season; they are sprayed every couple of weeks with a soap-based pesticide mixed with neem oil to ward off pests and every alternate week with a seaweed fertiliser. The task of pruning and training starts in November and continues until mid-February.

The garden behind the house has been transformed, with 16 tall yew beehives providing structure in borders overflowing with roses, including white ‘Madame Hardy’ and dark pink shrub rose ‘Princess Anne’ with pale pink ‘Queen of Denmark’ above it flanking the doorway. The planting includes herbaceous perennials and annuals, such as purple Campanula persicifolia, lime green Alchemilla mollis and white foxgloves, Orlaya grandiflora and Omphalodes linifolia.

The planting of the herbaceous borders at the back of the house is evolving as time goes on, most recently with the help of Sissinghurst head gardener Troy Scott Smith, who leads some of Susanne’s popular gardening and floristry courses here. They have refined the planting in these borders to bring in a mix of perennials and annuals for an extended season of interest, working within the framework of yew beehives, roses and scented shrubs. Delphiniums, foxgloves and pink willowherb give the borders a relaxed, cottage-garden feel, while smaller, delicate plants such as Omphalodes linifolia weave around, with Campanula patula and Dianthus superbus at the foot of the roses to lend a softer, more naturalistic look.

The colours in these borders are finely tuned to satisfy Susanne’s artistic eye, with infinite shades of pinks and purples contrasting with touches of white, lime green and the occasional – very occasional – hint of yellow. It is not a surprise to hear that, in addition to gardening, Susanne is enjoying exploring a new hobby – painting. ‘This is providing a wonderful distraction to help switch off from the garden,’ she explains. ‘I’m constantly thinking of new ideas, looking for new plants and editing the planting schemes.’ It is surely this heightened connection, this drive for perfection, that makes the garden at Upper Sydling House so special.
