An exhilarating Cornish garden that sits between the sky and the sea

Delighted to find a large plot by the sea, the owners of this Cornish garden had not reckoned on its cliff-like proportions and thin soil. But with plenty of perseverance – and a little expert help – they have created an exhilarating, atmospheric landscape that makes the most of the views

As the view down to the sea was revealed, they realised, says Robert, that there wasn't a flat piece of land to sit and look out. So building a terrace in the sheltered embrace of a new conservatory became a priority. As the Moules learned more about the history of the house (it was built in 1908 for two women who invited fellow suffragettes to recover there after hunger striking in prison), they uncovered the bones of the plot: two paths leading down to the sea and a path running across. They also uncovered huge boulders and outcrops of granite that, he says, 'stopped you in your tracks and dictated the ways smaller paths and flights of steps were added over time.

'We had a lot of help for the first two or three years that we were here, including an expert Cornish hedger to restore the walls,' Robert recalls. The couple concentrated on creating terraces in the upper part of the garden, always recycling materials from the site. Beds were edged with stone found in the garden, and granite window mullions salvaged from the former workhouse at nearby Madron were split into sills and steps. With no possibility of using a wheelbarrow, tons of chippings for paths had to be sent down to lower parts of the garden using pipes taped together to form a chute.

At last, with only bamboos, hydrangeas and the sculptural Monterey pines remaining, the couple were able to plant wherever there were suitable pockets in the thin, free-draining soil. Some early mistakes were perhaps inevitable - including positioning their beloved rhododendrons in the upper part of the garden, only to see their leaves shredded by the brutal salt-laden wind. They planted 'too big' and saw plants being ‘literally carried off’ by powerful gusts, and lost a host of exotic grevilleas and proteas one winter, when the usually mild temperatures suddenly dropped to -9°C.

Huge pale plumes of pampas grass (Cortaderia selloana) catch the eye among the richly textured planting on the side of the valley that slopes down to the sea. Low mounds of Hebe diosmifolia provide a foil for a host of plants including bright green ferns, spidery red phormiums and hydrangeas with soft pink and bright blue blooms

But then came the successes. The astounding front wall 'began as three small pots of erigeron', says Robert, who remembers a passer-by announcing; 'You'll regret planting those.' The exquisite aeonium wall came to life by 'bashing a flower head against the stone and pushing the seeds into the cracks'. There is a wonderful photograph of Carol planting the first tree fern that came in a two-litre pot. These now form tantalising groves, which tower above your head and are key to the feeling that this is a garden to lose yourself in.

Dangling bright cerise fuchsias line the path as you explore further. There are craggy, windblown haw thorns and luminous stands of the native fern Blechnum spicant with ladder-like fronds that are a fresh pea green when new, and bronzy-brown as they age. There are shimmering, wiry grasses and gorgeous stretches of silvery-grey Celmisia semicordata, the New Zealand daisy, like a tiny, repeating astelia. As you squeeze through a gap in the bamboo, the next view is always pulling you on: a boulder erupting with huge scalloped leaves of Bergenia ciliata; a dazzling red hot poker; a shaggy Cordyline australis outlined against the sky.

Despite years of painstaking work, the Moules' patient and intuitive enthusiasm remains undiminished. 'It's the intensity of the light and the blue and sparkle of the sea,' says Carol. 'We never tire of it.' From an almost impossible plot, a richly textured, breathtakingly lovely garden has been brought to life.
