I first came to Harlow Carr as a student in 1997 when it was still run by the Northern Horticultural Society. Despite having few resources and a
small garden team, the passion that the garden evoked among its staff was overwhelming. It was the toughest year of my horticultural training, working on heavy clay, in sub-zero temperatures and a wind that
The stream is central – literally – to Harlow Carr, and the relationship between it and the garden is a defining characteristic. Within the Streamside garden, paths echo the meandering beck, and beds ebb and flow in their design to reflect fluidity. Running east to west, the natural watercourse is a haven for wildlife such as dippers, tree creepers, weasels and voles. Like a thread it knits the formal and woodland sides of the garden together with distinctive yet lush planting.
New plantings began in January 2012, replacing some of the design
which had not changed since the days of the
Northern Horticultural Society. Many plants were lifted and divided, creating repeat planting. Within the new
design plants such as Iris ‘Shirley Pope’,

prevented by using the practice of ‘willow spiling’. This traditional technique uses live coppiced willow stems pushed vertically into the ground and horizontal rods woven back and forth, basketweave-style. This ‘living hurdling’ has done much to stabilise the bank and has provided some excellent planting pockets. It also provided a sustainable source of willow (harvested every two years) for use in the garden. »
Bartley hybrids, P. Harlow Car hybrids and Rodgersia pinnata ‘Chocolate Wing’ blend together. Further along the path, Gunnera manicata, Lysichiton americanus, more Harlow Car primulas and Himalayan blue poppies (Meconopsis) continue to inspire. These plants thrive in the cool moist air here, which also provided an ideal location for the RHS Plant Trial of perennial blue-flowered Meconopsis which concluded in June.
Dealing with floodsIn recent years, heavy rainfall has caused flash flooding, which led to large pockets of erosion, undermining tree roots and rocks. While our flood management plan is being phased in, further damage is being

Alpine Zone bedsSince the completion of the Alpine House four years ago, the Alpine Zone has continued to develop. The slate crevice walls have been most successful, providing an ideal setting for plants such as Globularia trichosantha and Lewisia tweedyi; and each year our horticultural trainees are given the opportunity to plant up their own alpine troughs for display.
The main focus for future development will be the two grassed areas in front of the Alpine House. At present the turf is left to grow long with curved paths mown through it. This meadow effect has led to the idea of creating an alpine-type meadow of annuals, perennials and bulbs similar to those found in the Picos de Europa in northern Spain.
Harlow Carr Horticulturist Amy Smethurst visited the Picos this year on an RHS-funded bursary with the Alpine Garden Society. She studied alpines and wildflower meadows in their native habitat, and we hope to create something similar here.

could bite your fingers off, and yet the garden worked its way into my heart.
In 2001 the Northern Horticultural Society merged with the RHS, making Harlow Carr its fourth and most northerly garden. Its history is embedded in the landscape – with water at its heart, running through its gullied veins. Although mineral springs had been discovered here centuries before, it was not until 1840 that a spa was developed on the site, including a bathhouse with heated sulphurous water, and a pleasure garden.
The spa’s popularity dwindled between the wars; eventually in 1949 the Northern Horticultural Society, led by Colonel Charles Grey, chose Harlow Carr (at that time spelt ‘Harlow Car’) as a place to trial plants for hardiness in the North of England.

With the ever-increasing interest in fruit and vegetables, the Kitchen Garden welcomes more visitors than ever. It has everything from chickens to sweet peas, and is a hub of creativity demonstrated in the living willow trellis constructed by the gardeners.
On the slope south of the Alpine Zone, the garden is laid out in a series of raised beds. This allows the soil to warm up faster, and each year the soil is improved with our own compost. This demonstrates how to manage heavy clay soil and how to plan crops for the best use of space.
Flowers and herbs are planted among the vegetables as companion plants to deter pests, but also to encourage beneficial insects, particularly pollinators for fruit.
Planting follows a three-year rotation cycle and includes heirloom cultivars such as tomato ‘Aunt Ruby’s Green Cherry’ and ‘Crimson Flowered’ broad bean. Sweet peas are always a favourite, along with our cutting garden and its drifts of annual flowers, perennials and bulbs. A stand of coppiced willow supplies the garden with much-needed material to create plant supports, edging for beds and creative projects.
Rhubarb has a long association with the North and we grow many Yorkshire selections such as those from the Stockbridge Technology Centre (selected for forcing). ‘From garden to table’ is the ethos of this garden, reducing food miles and eating crops freshly picked. We invite local chefs to demonstrate at events, cooking in an outdoor oven – using Harlow Carr charcoal created on site using our own charcoal burner.

can be heavy at times, which has caused substantial flooding over the last nine years, most notably in 2004/05. All these elements combine to create a mosaic of environments, which makes the garden a truly special place.
Green philosophySustainability underpins decisionmaking at Harlow Carr and was an important factor in the 2005 redesign of the Main Borders, the focal point of the garden. The prairiestyle planting includes bulbs and herbaceous perennials with grasses planted closely together in drifts to provide support.
Wildflower meadows are part of the surrounding environment and we continue to integrate them even in formal parts of the garden, increasing biodiversity, particularly near the Bramall Learning Centre.
More recent developments have included the Alpine Zone, high on the south side of the garden with views across the woodland.
The Main Borders (above) have a long season of interest; springtime bulbs

Climate and soilThe garden covers 23.5ha (58 acres)and is 155m (508ft) above sea level. Its soil is acidic clay, varying between pH4.8 and pH5.6 across the site, and heavy to work – so we take every opportunity to add compost and grit to new planting. We will grow more of the hardy, acidloving plants that thrive here, such as rhododendrons, camellias, heathers and Meconopsis.
The lowest recorded temperature last winter was 14.5�c (5.9�f); as with other RHS Gardens we have had to rethink our plant selection due to prolonged cold. The topography of the site also influences planting, as temperatures can vary by a few degrees on a winter’s day – from the comparative warmth of upper slopes to a hard frost by the stream. Rainfall

RHS Garden Harlow Carr
Ongoing developments at Harlow CarrManaging the environment sensitively is of utmost importance at Harlow Carr. One thing we cannot do is predict the weather and what it unseasonally throws at us. Having a sustainable drainage plan in place means that by 2017 we will no longer experience the ravages of flash flooding. Many tributaries flow into, and through, the landscape here. Some are natural springs; when the water table rises, Harlow Carr really feels the impact.
In phase two of the plan we intend to expand a small pond on the Lower Tarn lawn to help control the flow of water running through the garden into Harlow Beck. This will also allow us to refurbish old planting areas, to renovate many of the small tributaries around the pond that have become silted up, and to reposition large rocks that have become displaced.
Expanding visitor horizonsThe ‘Woodland Vision’ part of the master plan is well under way with the creation of new paths through the woodland and into the arboretum. This includes increasing our numbers of Rhododendron species and camellias, which thrive on Harlow Carr’s acidic clay soil.
A Birch Walk, and new understorey planting with trees for autumn colour, are all designed to draw the visitor to places within the garden they have never been before. We are particularly proud to hold a National Plant Collection of Dryopteris (ferns). National Plant Collections are important to the survival of plants – and with this in mind we have decided to build up our collection of Meconopsis (Himalayan blue poppy), which was once the symbol of Harlow Carr.

The Alpine House (opened 2009) allows us to grow more than 2,000 alpine plants, including many different Androsace and Dionysia.
Bulbs play an important part to our year, as our growing season is not as long as in southern England. Early-season impact is important, so each year we plant thousands of bulbs, including a river of 20,000 Narcissus ‘Actaea’, N. ‘Petrel’, and N. ‘Thalia’.
Harlow Carr is very much a legacy, and it is a privilege to work in the shadow of Geoffrey Smith (Super-intendent 1954–75). He brought the garden to prominence through his impassioned work and creative spirit, passing on to us an extremely special garden that will continue to delight for many years to come.
Lake enlargement and Gardens Through Time The Gardens Through Time are seven compartmentalised gardens built to commemorate the bicentenary of the RHS in 2004. Celebrated by the BBC TV series of the same name, they plotted gardening trends through history from the Regency period to a contemporary garden inspired by the past.
Nearly 10 years on, these gardens have evolved from the original planting schemes. Still influenced by their historical context, and keeping the structure of the gardens intact, we regularly try to create something different, yet relevant and inspiring to visitors. For example, the MidVictorian Garden, where once formal bedding was displayed, became a potager bed with a mix of orna men tal flowers and vegetables – which then became a meadow mix of annuals and
more recently a cutting garden.
