A 17th-century priory in France converted into a medieval-inspired topiary garden

An inspiring sense of complete peace pervades the garden of Le Prieuré de Vauboin, an old priory in Sarthe, in western France, following its medieval-inspired conversion into a green sanctuary defined by formal parterres and a spectacular array of box topiary

Today, the garden is composed of three main parts. As well as the hortus conclusus around the house, Thierry bought a further half hectare years ago, made up of a steep bank behind the house and a level area, yet to be developed, at the top.

Once the walled garden nearest the house was complete, Thierry began on the second garden on the bank, clearing numerous trees and making sense of the thicket of wild box. ‘The steep terrain and shade of the large deciduous trees led to some astonishing shapes,’ he says. Unlike the strict geometry in the area below, here he followed the underlying sculptural nature of the box, clipping it into shapes and unique forms, each with a distinct personality. ‘I use my instinct and allow the plants to guide me,’ he explains, admitting he is far more interested in these irregular forms than the standard topiary.

Gunnera manicata thrives in the damp conditions beside the spring-fed stream, its sculptural leaves providing dramatic interest. Seen beyond is the labyrinth garden, where cinder pathways thread through geometric topiary forms.

Some forms are totemic, others expressive; some work as isolated pieces, others as part of a collection. Thierry points out those that reference artists such as the Japanese painter Katsushika Hokusai, known for The Great Wave off Kanagawa, Henri Matisse and Joan Miró. Some are cascades, while others resemble dancers, umbrellas, garlands, pompoms and eyes. There are many wonderful vignettes, too, which lead visitors as if drawn by a magical thread through the varied spaces.

His energy, passion and familiarity with each plant is remarkable – as are his techniques for creating the shapes. One of the most interesting is tightly clipping foliage on bare stems to encourage growth until the trunk is clothed in leaves.

The owner and creator of the garden, Thierry Juge, has developed various techniques to shape the box. Here, in the upper garden on the slope behind the house, each form is unique as he allowed the wild box plants he found growing there to guide his approach.

I ask if he has a favourite and, on the top path, Thierry points out his chouchou (darling) – a particularly elegant form with sinuous branches supporting variously shaped pompoms. ‘It changes so much depending on the viewpoint,’ he says. And it is truly fascinating how the mass and void and light and shade, as well as the interplay with the forms around it, alter one’s perspective.

Evidently, the majority of the planting here is box and, although it is beautiful and extremely versatile, there is no ignoring the fact that it is increasingly difficult to grow healthily. Box tree caterpillar is a particular problem and can decimate plants, so is Thierry concerned? ‘The important thing is to not panic,’ he says. ‘You must be vigilant and understand the life cycle of the caterpillar in order to eradicate it.’ He recommends spraying with a biological control every eight weeks from spring through to autumn, when the caterpillars are active.

The garden has won the coveted title of Jardin Remarquable (an award given by the French Ministry of Culture) and also the first prize for the nationally recognised Prix de l’Art du Jardin from the Fondation Signature and Ministry of Culture. ‘When I began creating the garden, I never thought for a moment that I would receive visitors, let alone that it would become recognised as exceptional,’ says Thierry. ‘It’s a complicated garden.’ That may well be, but his devotion to it is clearly straightforward and complete.
