Claire Wright, BC

Garden is a Verb: Creating our garden in the Cotswolds

Claire and Jamie Wright are avid gardeners in Vancouver and the Cotswolds. They hosted the speakers’ dinner for our Study Weekend in 2013 in their amazing home, then opened their beautiful garden for our attendees.

Claire and Jamie are Anglophiles and have a passion for scavenging reclamation yards for architectural discards: brick, stone, iron, and terracotta.

In her working life Claire taught English part time at UBC for over two decades. Part time because they have six kids and 15 grandkids; they were, and are, their number one priority.

Claire will speak about crafting their garden in Snowshill. It is a talk about the steps forging their garden, more than a talk about. Says Claire: “I garden as half of a couple and a great part of my gardening joy is gardening with my husband. We dream it — then we clear it, and dig it, and plant it and tend it together. By happenstance, we bought the property in England on our 40th wedding anniversary and just adore being there (mostly in October, February and May). The last two years we have opened Tower Close for the National Garden Scheme and a few other organizations.”

Fergus Garrett – Great Dixter, Northiam, UK

Fergus Garrett was raised in the United Kingdom and in Turkey, studying horticulture at Wye College, graduating in 1989.

Fergus has held the position of Head Gardener for the internationally acclaimed Great Dixter Garden in the UK since 1993. The charismatic gardener and writer Christopher Lloyd (1921-2006) with his unique gardening skills taught Fergus to keep the gardens of Great Dixter constantly changing throughout the seasons and to be adventurous in trying out new plants and plant-combinations.

In 2003, Christopher Lloyd founded The Great Dixter Charitable Trust to secure the legacy of Great Dixter House and Garden and in 2006, Fergus took over the position of the CEO. The Friends of Great Dixter and their continuous support helps the Trust to keep Great Dixter House and Garden open to the public, to develop educational programmes for all age groups and to make more people aware of the richness and importance of the biodiversity of Great Dixter’s gardens, meadows and woodland.

Fergus believes in passing on his knowledge and expertise through the national and international student- and volunteer-programmes at Great Dixter and via the many worldwide lectures he gives each year. He is a hands-on gardener and plantsman who has a keen interest in working practices. He is interested in ecology and how an ornamental garden and biodiversity interact. He is also keen on woodland management and green wood working. Fergus has written many magazine articles and lectures widely both nationally and internationally.

Today, Fergus continues with his role as CEO and Head Gardener at Great Dixter as well as spearheading several projects including the greening up of urban and suburban communities, biodiversity related projects in towns and villages, and training students from all over the world in the Dixter style of flower gardening.

Fergus’ hobbies and interests are looking at plants and plant communities in the wild; all things natural; geology; rocks; baskets; the sea and fish; cooking; boxing; Turkey and anything Turkish; rural crafts and nice people.

Fergus has been awarded numerous prestigious awards, culminating in 2019 with the highest accolade the Royal Horticultural Society can give: The Victoria Medal of Honour (VMH).

Presentations:
‘’Biodiversity at Great Dixter’’
Great Dixter is an iconic garden in the South East of England. It was the home to the late Christopher Lloyd – undoubtedly one of the greatest gardeners of our time. The recent biodiversity audit at Great Dixter has revealed how extraordinarily rich Great Dixter the gardens and estate are in wildlife. The garden hosts over 40% of the UK bee species count just within a few acres, including many rare and scarce species. Fergus will give the background to the biodiversity audit, uncovering the process involved as well as breaking down the reasons for such diversity, especially in an intensively gardened flower garden full of flowers.

The findings from Great Dixter will relate directly to other gardens large and small proving how important a resource these spaces are for conserving some of our most threatened species. Collectively, along with roadside verges, brownfield sites, and urban and suburban spaces, gardens can play an important role in the future.

‘‘Great Dixter: Past, Present and Future”
Fergus will talk about the history of Great Dixter, the 15C manor house and its restoration by the famous Arts and Crafts architect, Sir Edwin Lutyens. He will explore the influence of Nathaniel Lloyd on its infrastructure and design, and Daisy Lloyd, his wife, on the garden, which she softened with her semi-naturalistic style. It was she who was the major influence on their youngest son, Christopher, who became one of the world’s greatest gardeners and garden writers.

The design of the borders, the planting style, meadow gardening and the importance of a biodiverse garden will be discussed, including the experimental and creative aspects of each. Fergus will also discuss the way forward for a sensitive historic garden and estate such as Great Dixter, with reference to the setting up of The Great Dixter Charitable Trust to protect the legacy of the Lloyd family.

Fergus will share his memories of Christopher (Christo) Lloyd, their relationship, the way they worked together to develop Dixter, how they challenged and experimented with garden design, made decisions, and took the garden to another level.

Amy Sanderson – Stellata Plants, Saanich

Amy Sanderson is a gardener and owner of the specialty nursery Stellata Plants in Central Saanich. Originally from Edmonton, Alberta, Amy’s unquenchable thirst for better garden plants sent her on a study tour of English gardens, including Beth Chatto’s and Great Dixter. Subsequently, there was no choice but to move to Vancouver Island and open a nursery focused on resilient perennials. With a passionate interest in the future of ornamental horticulture, in 2018 Amy coordinated the first international Beth Chatto Symposium: Ecological Planting for the 21st Century.

She is a regular volunteer in the Doris Page Winter Garden at the Horticulture Centre of the Pacific. You can find regular  updates on Instagram: @amysandersonflowers or @stellataplants

Presentation:
“Making Abundance”
The first five years of gardening and starting a specialty nursery on Vancouver Island have been a roller coaster. Every year has seen infrastructure improvements and garden expansion, experimentation with new plants in collaboration with new  friends, novel weather extremes, and deeper exploration of Pacific Northwest ecosystems. Aided by the time-tested  techniques of unfounded optimism and turning a blind eye, this lecture will revel in the joy of increasing seasonal dynamism, colour, and diversity with flowers in a garden culture that continues to champion irrigated evergreens.

Dave Demers, Cyan Horticulture, Vancouver

Dave Demers’s love for gardening sprouted early in life—he had his first greenhouse by age 10 and started a local garden club before graduating from high school. After studying horticulture in Montréal and New York, he travelled the world for internships in a variety of botanical collections and for plant-hunting expeditions. A Quebec transplant, Demers moved to the West Coast to work at Heronswood and finally settled in Vancouver, BC, where he runs Cyan Horticulture, a design/build/maintain landscape firm, as well as a small specialty plant nursery, Cyan Plants.

Presentation:
“Maximalist Gardening – Making the Most out of our Changing Ecologies”
Gardening is hip again: homeowners, designers and politicians alike seem to embrace plants for their many attributes. The importance of biodiversity – and bioabundance – has become a rallying call that gardeners are well equipped to answer.

And yet, the pressure of being under the spotlight, the finite resources and a changing climate, all contribute to making  gardening more challenging than ever. In this talk, I will share some of my experience as a designer, a gardener and a former elected City official. I will go from a humble hell-strip trial to the expansive lawn-gone-wild roof meadow of a stylish furniture  store, from no-mow City parks to generously planted private gardens.

SPEAKERS

Tony Spencer – is the internationally-recognized Canadian writer, digital creator and planting designer behind The New Perennialist, an influential blog focused on Explorations in Naturalistic Planting Design. (www.theperennialist.com) He also hosts The New Perennialist talks, a webinar series featuring influential design innovators in the genre.
In 2024, Tony won his second ‘Top Landscape Design Award of Excellence’ from the US-based Perennial Plant Association (PPA) and in 2023, he was named PPA ‘Garden Media Promoter’ of the year. He is also winner of the 2024 Media Awards’ ‘Silver Laurel Medal of Achievement for Social Media’ presented by GardenComm.

Day to day, Tony is a puckish ringleader for the naturalistic movement all while experimenting on a new series of wild-ish gardens at his beloved cabin in the rolling hills of Mono, Ontario.
The New Perennial Movement has inspired designers worldwide to pursue a more naturalistic approach in their work. In his first talk for us, “Open Source: Origins of the New Perennial Movement”, Tony will trace the movement back to its early roots in northern Europe with a look at the seminal figures including Piet Oudolf who started it all. Then he will loop around for an overview of the New Perennial Movement and how designers and gardeners are connecting through their uncommon passion for a wilder vision of the modern garden.
Tony’s second talk “Wildscaping: Planting Design with a Canadian Twist” was recently presented at Italy’s ‘Landscape Festival’ which is recognized worldwide for its visionary content on design and ecological health. It offers an overview of Tony’s diverse projects- woodlands, ponds, green roofs, dry gardens- with a focus on Wildscaping and designing for climate change.

Loree Bohl – lives in Portland, previously Spokane and Seattle, making a complete PNW triangle. After purchasing her Portland home in 2005, Loree fell in love with the vibrant horticulture community in Oregon.
Her love for agaves, cactus and all things spiky—despite the fact she lives in “rainy” Oregon—was the inspiration for her blog’s name, “Danger Garden.” She publishes new stories 3 times a week that include photos of her garden, her travels to other private and public gardens, visits to nurseries and other random “planty” things she finds interesting.

Loree has served on the board of directors for the Hardy Plant Society of Oregon and Pacific Horticulture and is on the Garden Bloggers Fling advisory committee. She has written for Pacific Horticulture; the Oregon Association of Nurseries magazine, Digger; the Rock Garden Quarterly, and Better Homes and Gardens. Her first book “Fearless Gardening: Be Bold, Break the Rules, Grow What You Love” was published by Timber Press in 2020. She practices the fine art of garden “cramscaping” and is a firm believer there is always room for one more plant.
Loree is a fearless gardener whose own garden features a broad array of containers, many of which are unique combinations of found objects, most of which required seasonal movement or reconfiguring. Her talk for us “Danger Garden, Contained’. Is newly created for our Study Day and will focus on these container plantings.

Philip MacDougall – has long run his not-for-profit nursery, Chlorophyllia, a specialty nursery that focuses on woodlanders ignored by the ravenous deer. Philip scours the world (wild and marketplace) for new and interesting plants, with a fine focus on epimediums and ferns.
He has been a vendor at our study weekends and various specialty sales around the Lower Mainland for decades, and his home garden/nursery was on the Vancouver Hardy Plant open garden Fraser Valley day in 2023. A discerning reader of Dan Hinkley and Far Reaches catalogues, or the UBCBG database, will note many subtle references to Philip’s collections.

Like Loree, Phillip’s talk “Japan Meander” is newly created for VHPG members, his description “A visit to only far too few of my many favorite Japanese plants, peeks at several of Japan’s best gardens, plus onsen, temples, udon and an atomic bomb. I’ll talk on how Japan’s aesthetic has influenced our own much more western garden.”

DANTE BAIES – Vancouver, Canada

Talk:
A Painter’s Garden – The story of Monet’s garden in Giverny: a behind-the-greens look at its transformation from cider orchard into art icon.

Many of you likely know me from my time as a regular volunteer at the much missed Free Spirit Nursery. What you may not know though is that before focusing my attention on evangelizing choice hardy perennials, I spent the summers of 2015-2017 toiling away—weeding, watering, digging, deadheading, and taking way too many photos—at Monet’s garden in Giverny. Terrified though I am at the prospect of doing so on such short notice, it is with fevered enthusiasm that I am putting together a presentation for you on what I learned about Monet and his iconic garden while I was there.

Dr. HENRIK SJOMAN – Gothenburg, Sweden

Talk:
The Essential Tree Selection Guide.

As Scientific Curator at Gothenburg Botanical Garden, and Senior Researcher at the Swedish University of Agricultural Sciences, and Honorary Research Associate at the Royal Botanic Gardens, Kew, Henrik’s work is mainly focusing on developing knowledge of site adapted plant use for urban environments. Finding ‘plants of tomorrow’ means to combine traditional plant hunting of less common species with research and evaluation, creating a diversified approach to a resilient urban forest suited to a future climate. Henrik co-authored ‘The Essential Tree Selection Guide’ published by Kew, co-authored with Arit Anderson.

Thomas Hobbs – Southlands Nursery.

Talk:
Garden Inspiration in France.

Tom Hobbs is well-known in the gardening world throughout North America and beyond as a plant guru, floristry specialist, and general aesthete. His flair for knowing how to inject excitement, style and opulence into a garden or any other space has, without doubt, had an invaluable influence on garden-making in British Columbia and much further afield.

Tom became known for operating the first ‘artistic’ floristry shop in the Vancouver area. However, the opportunity arose around 1991 to take over an existing nursery in the Southlands area. Tom not only for improved the nursery, but expanded the indoor plant merchandise and décor items, an area that Tom continues to expand.

Tom and partner, Brent Beattie, often open “The Farm’ to Vancouver Hardy Plant members.

This rural estate offers great lawns with sweeping views, informal islands of true treasures under giant conifers, a landscaped lake inserted into the forest margin, a formal kitchen garden that includes beds for breeding Iris, one of Tom’s favourites. There are architectural elements, follies and surprises at every turn. Tom has written two books, ‘Shocking Beauty’, and ‘The Jewel Box Garden’ based on his previous garden.

Douglas Justice – UBC Botanical Garden.

Talk:
Low-Maintenance Landscapes, Urban Tree Canopy Targets and other Myths.

Douglas Justice is the Associate Director, Horticulture and Collections, at UBC Botanical Garden. He is also an adjunct professor in the School of Architecture and Landscape Architecture at UBC and the Program Manager and an instructor for the Botanical Garden’s Horticulture Training Program. He co-authored The Jade Garden: New and Notable Plants from Asia, and wrote a Field Guide to Ornamental Cherries in Vancouver with volunteers from the Vancouver Cherry Blossom Festival. Douglas wrote the text for the mobile app Vancouver Trees and is now working to complete a similar volume describing cultivated shrubs in Vancouver. His pandemic project was co-authoring the book, The Lives of Leaves, which is now, finally, available in North America.
