A Clapham garden where every inch is filled with lush planting

For over 40 years, garden designer Christopher Masson has used his south London garden as an ever-evolving testing ground for his ideas, in which every inch is crammed with layered planting to create a lush and immersive space with appealing vistas.

His own garden has always been a haven to return to, as well as a place to develop his design ideas. ‘I use it as somewhere to try out new plants that I think might work in a client’s garden,’ he explains. ‘Most of them are grown in pots, so that I can move them around easily.’ Some planters are completely hidden by the plants; others are artfully placed on pillars, tables and ledges to create a mixture of different heights. ‘You can’t just have pots at ground level: plants need to reach for the light,’ observes Christopher. ‘This is a north-east-facing garden, so you have to harness the light and make the most of it.’

When he first laid out the garden, Christopher designed it with a T-shaped lawn. ‘I realised I had made a mistake,’ he says. ‘It was completely impractical in winter because it wasn’t getting any light, so it had to go.’ The lawn was replaced by an off-centre path consisting of rough York stone, granite setts and cobbles. The garden room has also had various iterations. ‘It was in totally the wrong place to start with,’ explains Christopher. ‘I was using the sunniest spot – right at the back – for storage, yet this was the best place to sit.’ The new garden room, with wide glass doors opening out into a small and secluded seating area, now occupies this prime spot and is angled towards the setting winter sun.

‘Nothing is parallel or symmetrical in this garden,’ Christopher says. ‘Years ago, I started to lay things out with symmetry, but I now actually prefer to break up the symmetry, using different
structural elements to bounce through the garden and lead the eye. I think it makes a small space seem bigger. You can get lost in this garden – you can’t quite see exactly where the boundaries are.’

In terms of flowering time, the garden is designed to peak late, towards the end of summer and into autumn. ‘There is always so much going on in the garden world in spring and early summer,’
Christopher explains. ‘I prefer a garden that comes into its own between July and November, when people have more time on their hands to appreciate it.’

Late-flowering salvias, including deep purple ‘Amistad’, blue ‘Mystic Spires’ and brick-red Salvia confertiflora, are woven in among exotic evergreens such as tetrapanax, while statement pots of eucomis, agave and arthropodium create focal points up and down the garden. But, true to the variable nature of this space, these plants may be moved on next year to make space for new specimens, the pots juggled around to create the ever-changing vista that Christopher prefers outside his back door.
