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…

10 Years Of Modern Mint
On Valentine’s day this year (2024) Modern Mint, the company I started when I moved to Essex to explore a fresh, contemporary approach to gardening, will be 10 years old. The cliche is time flies… but it does! So much has happened in a decade, from studying topiary with Charlotte Molesworth, to clipping all over the UK (and eventually in the USA and Sweden) to selling shears and secateurs at garden shows and hiding away my reticence to give talks about gardening and topiary to Horticultural Societies across the UK. Ten years feels a good time to mark a new …
Garden Masterclass Trailer – The Modern Topiarist
In 2022 I did a free video for Garden Masterclass, the Annie Guilfoyle and Noel Kingsley run website that is a treasure trove of the great and good of the horticultural world – well worth looking through all the wonderful talks they have available, like meadow-maker James Hitchmough or nurserywoman Rosy Hardy. They are certainly inspirational! Perfect for watching and dreaming up new ideas during the winter months… As a follow-up to my Topiary Provocations video (which you can see on Youtube for free) I was asked to do a video for their Masterclass series on how to make topiary. …
Charlotte Molesworth’s Garden In The FT
The lovely garden of my mentor Charlotte Molesworth is featured here in the Financial Times in the last week or so… She has been interviewed lots of times but I thought this was a particularly great piece, with some photos done at unusual angles and different parts… so well worth a read.
