Chelsea Flower Show 2016 Preview: The Winton Beauty of Mathematics Garden


The more I explore what’s in store at this year’s Chelsea Flower Show, the more excited I get. On reflection I was disappointed by last year’s show gardens, very few having stuck in my mind a year after the event. This year will be different. Back-to-back with Sam Oven’s Cloudy Bay Garden will be Diarmuid Gavin’s British Eccentrics Garden designed for department store Harrods. Inspired by William Heath Robinson’s notoriously complicated machines, the garden will have a sunken Italianate pond, genteel terraces and topiary; as well as a wooden shed full of cogs, wheels and garden gadgetry. It may not prove to be the height of horticulture, but it will be fun, irreverent and something we haven’t seen before.

But the garden that fascinates and excites me most this year is Nick Bailey’s design for Winton Capital, one of those organisations I have never heard of, probably because I don’t have any capital. Having had horrific experiences at school I have never considered mathematics to be anything other than a subject to be avoided at all costs. Yet in this garden Nick Bailey (below) will attempt, and I believe succeed, in portraying the beauty of the mathematics using plants, sculpture and some very fine hard landscaping.

2016 will be Nick Bailey’s debut at Chelsea and I am thrilled to see an accomplished plantsman demonstrating his passion on Main Avenue. As Head Gardener at the neighbouring Chelsea Physic Garden Nick has invested enormous energy in reinvigorating a historic layout to amuse and inform a contemporary audience. He is experienced, knowledgeable, humble and engaging, a talent I expect we will soon be a lot more aware of.

The garden’s layout is based on the mathematical symbol for infinity (∞), with further well-known mathematical expressions and concepts described by the garden‘s sinuous path and planting layout; these include the division, multiplication and plus signs. The proportions of the garden and the structure of the elegant belvedere are based on the golden ratio and the closely related Fibonacci sequence. Etched glass panels on the belvedere’s upper and lower decks will illustrate the radial spirals created by plants of the Asteraceae family of flowering plants. An elegant water bowl designed alongside sculptor Giles Raynor will represent potential life, and through its shape (based on a pine cone to complement nearby Pinus sylvestris ‘Watereri’) shows the Fibonacci sequence in physical form. The maths is all a little beyond me, but I know something beautiful when I see it.

Flowing through the centre of the garden will be a sweeping band of etched copper symbolising germination and the growth of a seedling. Copper was chosen not only for its beauty and patina, but because nearly all plant life depends on copper and most data is transmitted via cables made of the same. The band emerges at one end of the plot, rising in height to become first a bench, then a stair banister and finally a planter that sweeps around the top of the belvedere. The belvedere is pitched 3.5m above the garden and will overflow with trailing plants.

Being a seasoned plantsman Nick has gone to town with the plant list, sweeping aside tired old Chelsea clichés. Plants of the Southern Hemisphere and Mediterranean, whose delicate leaves and wiry forms epitomise nature’s mathematical patterns, feature heavily in an extensive roster of unusual subjects. Species such as the rare Aloe polyphylla (spiral aloe), Pinus sylvestris ‘Watereri’ and Anthemis spp. show very obvious mathematical patterns in their foliage, seed and flower forms. Corokia cotoneaster (wire netting bush) and the unusual Sarcopoterium spinosum (thorny burnet) exhibit beautiful regular geometric patterning in their zig-zag growth habits which creates the impression of pentagons, octagons or heptagons. Ceratonia siliqua features in the garden for its quirky mathematical past. Its seeds are always identical in weight, leading them to be used as a measure or weight dating back thousands of years. The word carat (in relation to gold and diamonds) is derived from the common name of Ceratonia: Carob.

Purple and violet flowered perennials will feature significantly in Nick’s design, complemented with planting in tones of Chartreuse, silver and white. Foliage will be significant too with copper, pale-blue and silver repeating through the garden.


When it comes to winning medals, it’s all in the detail. Nick has enlisted three Japanese gardeners – Eiko, Tsyako and Motoko (above) – who will form part of a team of 40, of which 15 will be planters. Nick says, “These extraordinary gardeners have the capacity to wade into complex delicate planting schemes, make an adjustment and return without leaving a trace of them ever having been there. Though the Winton garden has elements of naturalistic planting, making this work is a precise science, a science at which Japanese gardeners are masters.”

Confucius said “Everything has beauty, but not everyone sees it”. Love the subject or loath it, Nick’s garden will ensure that next week we all glimpse the grace and symmetry of mathematics.
