Edith Hammer is a microbial ecologist interested in plant-microbe and microbe-soil interactions at Lund University. She has been intensively studying the mycorrhizal symbiosis, fungal interactions with biochar and soil aggregation processes. She recently developed microfluidic model systems that simulate the spatial microstructure of soil microbial habitats in a transparent material, so called Soil Chips that act like a window to the soil, and allows her to study microbes as they experience their surroundings, and the soil processes they perform.

Broadcast from the underground – the secret life of the soil microbes

Microbes build our soil and drive the important nutrient cycles that allow the circle of life. They are of invaluable importance for plant systems as symbionts, pathogens, and drivers of the nutrient cycles. This talk will allow you a sneak peak into the secret and crawling live within plant roots, biochar particles and the vastness of the soil labyrinth. With the use of “window into the soil”- microfluidic chips, we can eaves-drop on a world that otherwise is largely hidden to us: Jostling protists, tsunami-like drying-rewetting events, and fungi with character. Beyond the scientific potential, the chips can also bring soils closer to people and hopefully increase engagement in soil health conservation.

My passion is the history and culture of landscape, the relationship of humans and nature in the past, present and future. Having worked in my own practice with my partner James Basson for 25 years creating mostly, dry sustainable gardens I have been lucky enough to travel the world making show gardens and international projects that have intrigued me to see how different cultures interact differently to gardens. I am not particularly interested in plants themselves but more in how they work together in a garden to create an atmosphere, a story or a place that their users can relate to.

End user experience – designing for people not plants

Sites present difficulties to a designer. Traditionally we concentrate on the physical restrictions of a site; climate, aspect, levels, drainage and so on, but it is important to equally consider the intellectual difficulties of the site – what is the history, the culture, the local population of the site. In incorporating this into our designs we can encourage the end user to really take ownership,ensuring the longevity of the garden. This can range from a large community space or park to a small intimate private garden.

Looking at being careful not to over-design, rather to work with nature to tell a multi-layered rich story. The concept behind the concept.

The Snake in the Garden. Designing for Symbiosis

Utopia, the perfect place, is a form of paradise created not by God but by “man”. This has been transcribed in many cultures as gardens that embody the notion of order, wellness and how we perceive our relationship with nature. Now, in the Antrhopocene, we have both the capacity to destroy the rest of the planet and the understanding not to do so.

As designers, we ask the question, how do we construct on our beautiful and sensitive landscapes without destroying them?

Our team has worked on this problem for 20 years, understanding both the land and people’s relationship to it. Clients have opened our eyes, challenging our beliefs of the good and the beautiful.

Being passionate about design, we bring value by providing inventive and harmonious solutions to complex problems. Seeking the new equilibria, we think of the result of our efforts as designing for symbiosis: between humans and the other inhabitants of the planet, between humans themselves,
between old and new.  The lessons we learn throughout our journey are integrated into future projects, while our approach and aesthetic has gained legitimacy and developed a following.

Designing for Symbiosis reverses the trend of transformation as destruction by formulating transformation as a new synthesis, a cohabitation.

Nigel Dunnett is Professor of Planting Design and Urban Horticulture in the Department of Landscape Architecture at the University of Sheffield, and is one of the world’s leading voices on innovative approaches to planting design. He is a plantsman, designer and pioneer of the new ecological approach to planting gardens and public spaces. His work revolves around the integration of ecology and horticulture to achieve low-input but high-impact landscapes that are dynamic, diverse, and tuned to nature. Nigel’s work is based on decades of detailed experimental work, and widespread application in practice: he works as a designer and consultant and regularly collaborates with a wide range of other professions, and his work has been widely applied in the UK and abroad. Projects include: The Queen Elizabeth London Olympic Park (principal planting design and horticultural consultant); The Barbican Centre, London (new planting schemes for podium landscapes); Sheffield Grey to Green (Planting design for the UK’s largest retrofit inner-city greenway and water-sensitive scheme). Nigel is an Ambassador for the Royal Horticultural Society and is a former Garden Club of America International Fellow. He is a gold medal-winner at the RHS Chelsea Flower Show and won the UK Landscape Institute Award 2018 for Planting Design, Public Horticulture and Strategic Ecology, and the Fellows’ Prize for Most Outstanding Project 2018, both for The Barbican, London. Nigel has authored and co-authored key books on planting design, water-sensitive design, and urban rainwater management, Green Roofs and Urban Landscape Planting. His latest book is Naturalistic Planting Design: The Essential Guide’ (Filbert Press, 2019).

Transform: dynamic ground layers from sun to shade in parks and gardens

The reality is that the greatest areas of ‘greenspace’ that we have is found in existing and established parks and gardens, and yet most focus on innovation is usually on newly designed schemes. Most of this existing resource is low-quality, low-diversity, and low-interest. In this talk Nigel takes the case study of Trentham Gardens, UK to look at how large areas of existing lawns, gardens, parklands and woodlands have been transformed in simple ways, utilizing a ‘meadow aesthetic’ across the gradient of situations from sun to shade and wet to dry.

Future Nature: urban solutions that go beyond ‘Green Infrastructure’.

Meeting the challenges of the climate emergency requires radical, large-scale, transformational urban greening. This will mean working in areas outside of the boundaries of traditional horticulture or ecology. In this talk, Nigel goes through the practical details of two leading UK schemes: The Barbican in London, and Sheffield’s Grey to Green phases 1 and 2. Design, implementation, and ongoing maintenance are discussed, with an honest and up-front review of lessons learnt.

Olivier Filippi and his wife Clara run a specialist nursery, located in the South of France, dedicated to drought tolerant plants. Olivier and Clara started their research in the 1980s and since then have travelled extensively throughout the Mediterranean and to similar climate regions around the world to study plant adaptation in dry climates. Their experience of plants in the wild and their experiments in their own trial garden have given them a unique understanding of the needs of dry climate plants. Based on their knowledge of landscape dynamics across the Mediterranean, they continue to work on a new approach to low maintenance and pesticide free gardens for dry climate regions.

Olivier is a photographer and author of several books. He lectures frequently on dry gardening techniques and design inspired by Mediterranean landscapes.

Understanding nature

Gardens and green spaces, often traditionally designed mainly for their decorative interest, are now more and more designed as functional ecosystems which include positive interactions with beneficial insects and soil organisms. Understanding the long term dynamic of evolution of the garden seen as an ecosystem allows to decrease maintenance in drought adapted and pesticide free gardens. Olivier Filippi will explain how germination ecology in post disturbance Mediterranean landscapes can be an inspiration for low maintenance garden design in a changing climate.

Gardens for the Future

Designers in different climates tend to use gradients between herbaceous ecosystems based on summer flowering scenery and subshrub drought tolerant ecosystems relying on evergreen foliage and summer dormancy for their aesthetic interest. Climate change may bring a revolution in thinking along that gradient, blurring traditional frontiers between ‘Temperate’ and ‘Mediterranean’, particularly in artificial urban environments with high climate and soil constraints. Gardeners of the future may have to face a major change in the flora adapted to new conditions, a shift in aesthetic cultural perception and a change in gardening techniques, from soil preparation to maintenance practices.

“Same, same, but different” – LUSH PERENNIAL PLANTINGS

We all have the same goal – attractive plantings that require as little maintenance as possible.
There are different ways to get there. I will tell you about our experiences from the last 20 years at the west coast of Sweden.

How we introduced perennials in residential areas. Not only in perennial borders, but also as undergrowth and edging plants, together with flowering trees, shrubs and bulbs.

Are there completely maintenance-free diversified perennial plantings? I doubt it…
Luckily, we have created a way to save time for you – the 14-minutes method.

Ever since he started growing plants, Peter has tried to understand what it is that makes a plant establish in the specific place where it occurs in the wild, and then translating it to garden conditions. He has travelled to numerous places with climates similar to Sweden to see how plants grow in their natural environment. The trips, combined with great curiosity and own growing experiences, have given him an unusual understanding of what plants want – no matter how specific their needs are. Peter uses this knowledge in his landscape and garden design with great success and gives regular lectures on growing conditions, creating habitats and naturalistic plantings. Nature is always his greatest source of inspiration.

Peter is one of the founders of the Urban Growth conference.

High diversity plantings

With inspiration from the wild it´s possible to create low maintenance plantings with high diversity, in almost any environment. Plantings that don´t need irrigation, but have high ornamental values with continuous flowering through the seasons and beautiful winter values. Plantings that are important for biodiversity and can stand or even benefit from a more extreme future climate.

In my talk, I will show some examples and talk about the thoughs, behind some of my public plantings, as well as from Klinta Trädgård; our private garden and nursery.

What factors affect a planting and how is it possible to to turn the most problematic conditions to an excellent startingpoint? How to read an area, take advantage of the different factors and create possibilities for plants to thrive. How to make sustainable plantings with high plant diversity. Hot dry places in cities can be transformed to important environments for biodiversity. But in urban areas were many people live, the function and the aesthetic values are as or even more important. It´s also possible to combine all of this with stormwater management and other challenges. Maintenance is always the key factor to succes. A planting should solve problems, not create them.

What need a plant user to know about plants?

Perennial plantings should not only be elements created just for decoration, but also elements, that can play a biological role in a manageable way.

If we today shall be able to really work properly with perennials in a larger context – both as to their demands of maintenance and their role in the biodiversity – we must have knowledge not only through photos of their close-up appearance at prime time, but also their spreading
behavior, need for division, cutting back, staking and not the least – their water and soil demands. If we want to be able to introduce the perennials in nature-like or semi-wild contexts, we need plants that fit in here.

Known as “the crevice garden guy,” he is currently exploring the full breadth of possibilities of rock garden design by trying new things in public and private gardens, across the US and overseas. He has built dozens of these rock gardens from back patios to public parks. He’s authoring a book on the subject in hopes to permanently empower the gardening world with this beautiful, versatile and powerful plant growing system so that any plant collection can include saxatile plants. At home, he is a slave to native plant work in his water-scarce region by making unirrigated native gardens and meadows. An unrestrained plant whore, he hunts seed from his home desert-steppe in Western Colorado to that of Turkey, growing them in his own backyard nursery to supply his projects. He shares everything he learns on his blog.

Hardy Succulents: Beyond the Sea of Sedum

Succulents deserve some attention beyond the interior design fad. This is a program looking at a variety of hardy cactus and succulent species, for whom -15 or -20 C is not a problem, as well as species that prosper in European climates. We’ll also look broadly at their homelands and stories as well as see how they can be used.

The Modern Crevice Garden

Crevice gardens are evolving beyond being a strange rock garden novelty to being understood as the best way to grow certain plants, which is of great interest to collection-driven public gardens and hobbyist plant nerds. Recent developments have not only stretched the growable plant
palette in virtually any climate, but show us how varied designs and materials allow crevicegardens to provide ecological services while solving site problems at the same time. Their sheer variety ensures there is a crevice garden too, for any taste.

Lauren Springer has designed public plantings at Denver Botanic Gardens and the Gardens on Spring Creek in Fort Collins, Colorado where she created and tends a new ¾ acre garden that showcases more than 5000 plants suited to the climatic rigors of northern Colorado. She has written five books, including The Undaunted Garden and Plant-Driven Design. Lauren studied for five years and received her master’s degree in horticulture from Pennsylvania State University in 1989. She emphasizes plant diversity and ecologically sound horticultural practices and has been a propagator for 35 years, introducing many new plants to the American nursery trade, some her own hybrids. A pioneer in water-conserving plantings, she also seeks to create beauty with wildlife function. This commitment resulted in Audubon Society Habitat Hero awards for four of her design projects.

Inspired by the wild: making naturalistic plantings for beauty, adaptability, and creatures

In an ever more crowded and unnatural world, many of us find reconnection with plants and creatures in gardens and wild places. Lauren designs and tends diverse and beautiful public naturalistic gardens to make this connection accessible to more people. She will discuss distilling the essence of various natural plant communities to make inspired garden spaces, as well as plants and practicalities unique to creating
and managing such plantings.

Planting for sensuality: creating spaces that delight the senses and move the soul

What makes our gardens sensual? It can be much more than just the dominant and powerful visual seduction of color. Light, texture, fragrance, motion, and other components combine and change, stimulating our eyes and other senses in new and different ways that we feel as immediate, intimate, and present. Lauren will show how to enrich our experience through plant selection and creation of spaces that engage all the senses.

The conference will take place in Slagthuset (Swedish only), the former slaughter house of Malmö! A beautiful old building in central Malmö. Two minutes walk from the Central train station.

Malmö is in the middle of the so called Öresunds-area, also called Greater Copenhagen. It includes the southern part of Sweden called Skåne, as well as Copenhagen and the eastern part of Denmark. From the train station there are great connections to and from other Swedish cities as well as Copenhagen and the rest of Europe.



Klinta Trädgård AB (eng. ”Klinta Garden”) was founded by us, Peter Korn and Julia Andersson, when we took over the location of former herb & vegetable nursery Klinta Kryddor & Grönt in the autumn of 2015.
Julia has a degree in Landscape Planning from the Swedish University of Agricultural Sciences (SLU), and Peter is an autodidact plantsman. We both have extensive experience in the fields of horticulture and landscape design.
