How to make a white garden
If you've been inspired by the white garden at Loseley Park or Sissinghurst or just by the idea this will help you plan one.
First off, you've got to be committed. There's no point going 95% of the way and then throwing in a magnificently lurid Dahlia you've seen on Gardener's World or The Daily Telegraph.
Next, you need some strong, structural evergreens. Nothing sets off white flowers like dark green. And it's good to have some structure in the winter and to form a backbone to the garden. At Loseley Park they've used Viburnum davidii. It doesn't get too large and keeps a nice shape. You could also use Buxus sempervirens (box) or Taxus baccata (yew).
Something tall and willowy at the back of the border will add some height. Veronicastrum virginicum Album would fit the bill, as would Epilobium angustifolium Album or Digitalis purpurea Alba which would be good for a slightly shady border.
Working your way forwards, Anemone x hybrida Honorine Jobert is a reliable late summer flowerer. It can take a while to get going but its wiry stems will weave their way through other foliage.
One of the things you'll have noticed about most white gardens is that they are seldom all white. Touches of pale pink, grey and pale yellow add some depth to the scheme. This Allium Decipiens does just that with globes of the palest pink in late spring. Other pale pinks to think about include the fluffy spikes of Stachys byzantina and Linaria purpurea Canon Went with its delicate spires.
If you're lucky enough to have a good wall or fence don't forget about adding in some climbers - Rosa Iceberg flowers on and off all summer. And Tachelospermum jasminoides does several jobs - it's evergreen and produces masses of scented white flowers in July. Try a clematis to get an early start such as Clematis montana Henryi.
Variegated foliage is frequently used in white gardens and this Miscanthus sinensis Varigatus adds movement in a slight breeze, some structure through the winter and works really well with the pale yellow Anthemis tinctoria Sauce Hollandaise and the white flowers and grey stems of Lychnis coronaria Alba.
Other variegated foliage plants to consider are Cornus Elegantissima, Pittosporum tenuifolium Golf Ball and Euonymus fortuneii Emerald Gaiety. Do check the ultimate size of the plants before buying ...
You want to get the white garden off to an early start so bulbs are a must. My favourite, Tulipa Spring Green looks great with Narcissus Thalia or N. Actaea. Other white tulips include T. White Triumphator and T. Tacoma.
Following hot on their heels are Astrantia major Large White, liking not too much sun and a bit of dampness. Astrantia major Buckland has a slight pink tinge. You'll need to plant a few of these fairly close as they take some time to fill out, worth the wait I think.
And finally, if you're after an end of season show stopper then it's got to be a hydrangea. This one's H. Emilie Mouillere which fades to a lovely pink colour. Another favourite is H. arborescens Annabelle with enormous green/white flowerheads if it gets enough water.
If you've not the space for a hydrangea this is the point at which you can add in a Daily Telegraph dahlia, but make it D. White Star or D. Lady Kate or D. Bishop of Dover.
One thing to remember about white gardens, charming as they are, if you don't dead head regularly it will all look rather brown and ugly as the flowers fade.
Return to Allt-y-bela
Unable to resist another invitation to see Allt-y-bela, I trogged down the M4 in the pouring rain.
Last time I was here it was raining too. But, like then, the sun did come out, briefly. In late July this garden is all about the cottage garden and the vegetable plot. In early June it's all roses and wild flowers
It's the wild flower meadows that help the garden merge with the surrounding landscape. Of course they're not really wild in the sense of always having been here; they haven't, they've been planted and sown in the last ten years, but you wouldn't know it just by looking.
But even old wild flower meadows need to be managed - mown at the right time to allow seeds to fall and germinate, the flowers not allowed to lie in situ after mowing but be picked up so the soil fertility doesn't increase and additional species planted that may or may not be typical wild flower meadow plants. Like these Trollius.
The meadows are in fact quite a bit of work, but definitely worth it I think.
The roses were over by the time of my visit last year but this time they were just getting into their stride. I'd love to be able to tell you the names of them all but I found myself a bit distracted.
As the garden is in a bit of a valley the scent is captured and remains in the air, even on a wet day.
Often I have clients say they don't want any roses in their gardens. Memories of municipal monoculture or a faint whiff of the crematorium perhaps? But when planted amongst other shrubs or perennials they can really shine when in flower and disappear into the background when they've finished.
And roses' ability to climb makes them doubly useful, especially if you are short of space or have a few old apple trees that might not be looking their best.
Having a beautiful house does give you a bit of a head start in the gardening stakes. It does take a degree of bravery to turn an off-white ugly duckling into an uskan orange beauty (yes the typo is deliberate).
And when garden designers witter on about good bones and structure this is what they are refering to - good quality hard landscaping that has a beauty and a purpose and fantastic evergreen plants.
Or purple ones.
