One of the joys of the gradual easing of lockdown since June has been garden visiting. From The Newt in Somerset to Vann House in Surrey I’ve enjoyed several days off from a busy gardening schedule to explore some beautiful sites. At the start of August I went to The Savill Garden next to Windsor Great Park. Despite low clouds and fine rain my overall impression was of concentrations of vivid colours brightening dense ornamental woodland. Dazzling pinks and purples welcome you in the double borders leading from the visitor centre. Edged with pinky mauve Osteospermum, a block of warm pink Salvia microphylla is given an airy feel by clouds of Verbena bonariensis hovering overhead. Alongside are dark-leaved Dahlias bearing pom-pom flowers in puce, a shade which here looks better than it sounds. Puce is one of those words describing colour (heliotrope is another) which I associate with gloomy Victorian parlours.
In the Bog Garden I found more colour than I expected with the soft sky blue of bog sage (Salvia uligonosa) contrasting in both form and colour with the buttery yellow daisy flowers of Inula. I should mention that a welcome feature of this garden is the presence of plant labels. Spoilt by proximity to the world’s greatest botanic garden, I expect to find every plant clearly labelled in all gardens which are open to the public! But I accept the argument that whilst Kew is the repository of a priceless living collection of plants from across the world, the plants in many other gardens are to be enjoyed in their own right without a similar emphasis on identification.
The Summer Gardens consists of plantings of herbaceous perennials dedicated to individual colours. Some were vivid, indeed ‘brash’ as the visitor map put it (yellows, reds, pinks) and some cooler (white and blue). Mauve Cleome blended with the furry pink tails of Sanguisorba and a tall stand of Phlox.
In the blue border, alongside dainty Salvia ‘So Cool Blue’ with its almost black stems, I found a plant I’ve not heard of before, the blue lace flower, Trachymene coerulea. I mistook it at first as a form of Scabious, due to its plump lavender blue pin cushion flowerheads atop stiff stems. But the scale of the flowerhead (up to 5cm) prompted me to find the label. The RHS A-Z Encyclopaedia of Plants informs me that the plant is an annual or biennial from Western Australia, long-lasting when cut. The flowerheads are composed of tubular flowers which flare out into clusters of five petalled stars studded with anthers bearing white pollen, all supported by a claw of narrow sepals reminiscent of the setting for a large gemmed ring.
Echinacea purpurea ‘Virgin’ contributed its pearly white flowers to the green and white of another border, to one side of which Thalictrum ‘Splendide White’ was thrown into relief by the dark yew of an adjoining hedge. The mass of cup-shaped flowers resembled a 3m high swarm of white bees.
In another border red was represented by scarlet Dahlias with dark foliage (one of the bishop cultivars perhaps?), fronted by a profusion of red daisies which might be Echinacea ‘Hot Papaya’ although I cannot be sure as I failed to note the plant label.
That area of The Savill Garden called Summer Wood hosts a wonderful collection of Hydrangeas in muted pastels, a contrast to the primary colours of the Summer Gardens. There’s an excellent plant shop in the Visitor Centre where I bought a Bog Sage to use as a stock plant from which to take half a dozen stem cuttings. A week has passed and the cuttings remain perky, so I am keeping my fingers crossed for a success propagation. When they have taken and grown larger I shall pot them on ready to be planted out in a moist part of a garden next year.
On 7 August I did my third session this summer at Osterley on a day when the temperature reached 36.4% at Heathrow Airport 4 miles to the west. Gardener Ed thoughtfully deployed us to weed the shady cobbled courtyard outside the Study Base. After lunch we worked under the awnings over the tables outside the bothy, tidying the pots of plants stacked in the nursery area.
On the subject of propagation, at home this summer I have created a couple of shelving areas for young plants where they have grown enough to leave the protection of the glazed vertical cold frame which I use like a mini greenhouse in the summer months, leaving the lid permanently raised to ensure plenty of ventilation. The new shelves are simply upended wooden pallets: one from a bulk delivery of shredded horse manure in February and the other kindly donated by clients who were glad to find a home for it. Not only that but they drove it over to me when it was far too wide to fit in my car. I’ve attached the pallets to the outside of the fence where it faces east to the alley between my end of terrace house and the neighbouring terrace. Barely 15 cm deep they take up very little space and have created additional space just outside the garden.
I shall sign off with an image of the garden itself from a week or so ago, showing a palette of blue, white, pink and purple.
