Plants for Clay Soil
There are lots of plants for clay soil. Difficult as it is to work with, the opportunities to tend a fabulous garden of well-fed, strong and voluptuous plants are second to none (just try not to despair, at the end of the day, when trying to remove the clay from your boots!)
Roses are the absolute first choice for clay.
We made a beautiful rose garden for a client in Hampshire. It was on blue clay and halfway down a gentle slope, so got plenty of water. Each bed had a single variety of rose in, 15 plants per bed, and it looked fabulous as you peered through the hornbeam arch (we chose hornbeam, though not as nice a hedge as beech, because it could cope with the site.)
The client had wanted lavender and box to edge the roses and fill in any gaps – but there is no way they would have survived. Ilex crenata may have coped better, but we doubted its longevity (the site really was wet at times.)
So instead we built a small seating area, added a sculpture and made sure the grass sward was beautiful and cut consistently.
Simple and striking seemed the way forward in this case.
Val Bourne gives a rundown of some fantastic plants in her book The Natural Gardener: The Way We All Want to Garden: Preserving Nature’s Jigsaw. She said…
“Roses (even those old-fashioned beauties), viburnums, hostas, phlox, monardas and asters will love your garden.”
You won’t go far wrong if you just planted these!
The hostas may get eaten by slugs, so if you don’t want the hassle either steer clear of growing them, use copper rings around the plants, or add gravel and grit across the whole bed. Decide on your maintenance capabilities really, and how much time you want to spend on picking off and squashing slugs. It wouldn’t be our first choice of jobs to do…
If you do want to buy hostas then you can see what is on offer here – Jersey Plants Direct – they also sell a Viburnum opulus at a fair price if you type that into the search. Viburnums are solid plants (see the V. carlesii in the picture below) and they provide a cluster of flowers at the start of the season and then berries at the end.
Do plant them!
Cornus is another fine choice for soils that are damp – normally planted for winter stem colour, we also think they do a good job during the summer when in leaf – Cornus alba ‘elegantissima’ has a white margin on the green leaf, which provides a lovely calm backdrop for bigger summer flowers.
Astrantia is a favourite of ours, if you want something perennial. Let some aquilegia seed around it, maybe some campanula and forget-me-not, and you have a soft (possibly too soft? If so, add euphorbia palustris!) late spring scene of delightful flowers.
We always found, when growing dahlias, that lots of water helped. So though you will lose the tubers over winter in clay soil, putting them in for summer will give you a beautiful display. Crocus are currently doing a special offer on dahlias in there ‘bulbs’ section – so don’t miss it, go now!
That should get you started. Just remember to suit the plant to the place – that is what modern garden design is about, and it means the plant is happy and you won’t have as much work to do… unless (and it’s a fine problem to have) they grow too well…
All the plants we’ve talked about can be bought and delivered from Crocus or Jersey Plants Direct – Jersey Plants Direct offer a free delivery no matter the size of the order. Which we think is more than reasonable….
Or for decent books to use as a guide, try Beth Chatto…

Topiary, The Art Garden at The Henderson
The Art Garden at The Henderson in Hong-Kong has now opened to the public. I joined the project last March, to work with Gillespies Landscape Architects on the topiary that had been designed for the Art Garden, which gives a calm, green space below the extraordinary Henderson skyscraper designed by Zaha Hadid Architects. The garden has been designed with butterflies in mind, so lots of nectar plants, and has other art projects and installations within its footprint. The history of the site is interesting too – it was originally the first cricket ground in Hong-Kong! So still a green space….! …
ClipFest 2025
On Sunday June 22nd there will be Clipfest 2025 at Ichi-Coo Park in Surrey. It is a celebration of all things pruning and topiary, and I will be there in my capacity of teacher at the European Boxwood and Topiary Society to demonstrate tool cleaning and sharpening, and how to clip. Tickets can be found here on Eventbrite. We are hoping for great weather and to see lots of keen pruners getting their shears out and joining us at this amazing garden! And for more on topiary…
Secateur Holders
A present arrived from Norway today, from a student who visited last February to work with Chris Poole and I on learning topiary. His new hobby – a beautiful and neatly stitched secateur holder. Thrilled with this! The holder will save me keep losing my secatuers too…! Thank you Bernt! It was the same student who introduced me to the APA with whom I am doing a talk at the end of March. Tickets can be bought here for ‘Defining The Essence – Aesthetic Pruning in the Garden’. Do join the European Boxwood and Topiary Society for that!
