Sarah Price's idyllic Abergavenny garden, filled with her experiments in resilient and low-intervention planting

Sarah Price's garden appeared in House & Garden in 2016, when the designer had recently moved to her grandparents' house in Wales. But, in the past few years, she has taken it in an exciting new direction

‘I wanted to experiment with plants that grow in really dry conditions,’ says Sarah. ‘I laid it out like a mosaic with different depths of recycled sand, gravel and rubble, and I observe which plants self seed where. Because of the lack of nutrients, you can create really complex plant communities.’ She has found that plants that grow lush and tall in normal or rich soil are shorter and more robust in these harsher conditions. Some flower for longer; others that might flop in a rich soil make compact, domed shapes. ‘Generally, the plants are better behaved,’ she observes. ‘Field scabious flowers all summer long here, and the hollyhocks are shorter and stockier and don’t have rust.’

Designed with the look of a wild perennial meadow, the walled garden is planted with both native wildflowers and Mediterranean species, anchored with a few core plants that are repeated across the garden to hold the scene together and create unity. Sea kale, Crambe maritima, is one of these key plants, happy to grow in the coarser rubble, while Euphorbia seguieriana subsp. niciciana has a similar presence, its lime-green flowers blooming through summer to form ribbons that link all the other plants together. Grasses of different textures, such as airy Oryzopsis miliacea and bottlebrush Pennisetum macrourum, as well as umbellifers like Ligusticum lucidum, fill the gaps and emphasise the meadowy feel.

Then, through this fluid understorey comes an emergence of spires, including Digitalis ferruginea, Asphodelus lutea and Verbascum phoeniceum ‘Violetta’ – as well as striking orange Eremurus ‘Cleopatra’. Self-seeding species are part of the ephemeral nature of the composition, changing year by year and adding an unpredictability that makes each season exciting.

Although lower maintenance than it used to be, this is not the type of garden that can be left to its own devices: constant observation and editing is needed to make sure the balance of plants retains its intricacy. For this, Sarah has the help of Jacky Mills and Ian Mannall, both experienced horticulturists who understand this nuanced type of gardening. Watering is no longer on the agenda. ‘Many herbaceous borders look sad in a drought, but this garden looks amazing with no irrigation.’

Now that the walled garden is less time consuming, Sarah can give more attention to other areas. She has been enjoying developing what she refers to as the secret garden, accessed via a tunnel that runs under the lane next to her house. Using top-soil removed from the walled garden, she levelled the sloping site to make a new pond. She is gently shaping and adding to the wild flora here to make a secluded haven to share with the wildlife that have made the garden their home. ‘It felt wrong to disturb the existing ecosystem, so I’ve been planting perennials into the sward and cloud-pruning self-seeded saplings into interesting shapes. I work in quite an instinctive way,’ she says.

Like the no-dig method for vegetables, this low-intervention way of gardening is all about minimum soil disturbance. Planted into the long grass, perennials such as thalictrums, asters and wild peonies grow tougher and shorter than in a border. Emerging from the tunnel into the light feels like walking into a different world, the luminous pond reflecting the sky and mountain to give this enclosed space a dreamlike perspective. This is an intriguing garden that is all about nature leading the way; about subtle interventions rather than grand gestures; about gardening sustainably and sensitively rather than using precious resources. It could so easily revert to a blur of wilderness, but Sarah’s artistry prevents this from happening. ‘I’m always trying to work out ways to frame this style of planting, whether it’s the siting of a bench or piece of sculpture, or the creation of a sculptural hedge,’ she explains. ‘It requires areas of tidiness to offset the wildness.’

A view towards the house across the secret garden. Sarah levelled this area with topsoil from the walled garden and dug out the pond by hand, which has brought in many forms of wildlife. Damp-loving plants now colonising its margins include water irises, watermint, common rushes (Juncus effusus), Darmera peltata and yellow Mimulus luteus.

Modulating through the seasons, the planting in both areas brings different periods of intensity and quietness. ‘It’s the type of planting that you have to sit down and observe, and then the intricacies can be seen,’ says Sarah. ‘Gardening like this is all about being open to the opportunities that nature offers’
