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…

Start of the Whitby Topiary Library

I have been offered a space here in the centre of Whitby, south-facing aspect, with some raised beds in, so that I can make a Topiary Library. In my head, a topiary library is a place to showcase the common (and then not so common) shapes you can make out of topiary. With classical topiary plants, as well as some more unusual pieces. This Topiary Library can act as a reference for people to learn more about pruning and clipping. The space is small but the aspect is great and the beds are deep enough to put some plants in. …

Delivery After Dark – From the Makers of The Amelia Project

Last week I spent most nights stood in cold water streams on the moors of North Yorkshire, helping to film a new project called Delivery After Dark from the makers of the Amelia Project. I worked on the Amelia Project back at the end of 2024, lending my terrible vocal talents to a small part in the episode Didius Julianus. But this project is something new – and exciting! – and thankfully only needed me to be filmed, rather than to actually say anything. But not only did I have to stand in cold moving water at midnight, I also …

Modern Topiary (The Book) – Message From Lady Clippers, And Others!

My topiary book – Modern Topiary – has recently been put out as a PDF, which can be read for free. (Have a look here to download and read/share it!) Then last week I received a lovely email from Ann Perkowski of Lady Clippers, who are topiary and pruning specialists in New York (Ann is a brilliant pruning teacher too, who teaches at New York Botanical Garden… check out her work and Lady Clippers website.) Hi Darren, I had to write you how much I love reading your Modern Topiary. I’m not sure I’ll ever be quite done with it because I’m …
