How can they grow together in the garden? A detailed look at both genera with lots of information about growing them from seed. This lecture  was devised for those groups not keen on a “single genus” lecture.

    8. Woodland Plants in the wild and in cultivation – I enjoy growing hepaticas, cypripediums, meconopsis and many other species that grow in woodland sites round the world. We will take a look at some of these woodland plants growing in the wild, and see how we can adapt our gardens in order to grow some of these wonderful plants. I will also show you how I use a shade house to extend the range of species I grow. I also will dispel myths and mysteries about growing woodland plants from seed.

    Information: David Dickenson, a retired veterinary surgeon, has spent his last 13 summers in the Cévennes National Park in France. This mountainous area, sitting on the borders of the Atlantic and Mediterranean climates, is famed for its rich ‘alpine’ flora, including its 60 species of orchid. An elevation between 500 m and 1800 m, coupled with 3 key rock types, ensures one of the widest range of plant species in Europe. David Dickenson is an amateur botanist, benefiting from his close links with the team of the National Park, and has an intimate knowledge of the iconic species endemic to the region. He runs a web site illustrating and describing every the local plant you are likely to see (in French and English).


    1. A Tour Around my Rock – The Causse Méjean is a limestone plateau fringed with dolomitic rocks, displaying dramatic forms resembling ruined villages. This vertiginous tour takes your around just one of these rocks, the size of a mini-bus, but boasting over 50 alpine species which would put shame to anybody’s rock garden. Richly illustrated, some of their survival strategies are discussed. Find out how these plants survive a scorching sun, strong winds and interminable drought. And who needs soil?

    2. An Englishman in the Cévennes – enlarging on an article written for ALEPE, the local nature group in Lozère, this talk reflects on the astonishment on arrival in this wild corner of Europe, after half a decade in an England where nature has for a long time been trained and constrained into adapting to the demands of a modern society.

    3. The Barmy Botanists – as founder and leader of a local botany group, the Barmy Botanists, David Dickenson has made accounts of many of these outings available for download on his site ( Although these are in French (or rather, Franglais), they are richly illustrated with the local flora, together with maps.

    Information: Hilary and Austin have been trekking and travelling the world for well over 40 years in search of alpine flowers. Their journeys have taken them from the mountains of Europe to the Arctic Circle and Alaska; from the Himalayas and the Hindu Kush to the Snowy Mountains of South Australia, Tasmania and New Zealand; and from the Drakensberg Mountains of South Africa and Lesotho to the South American Andes.

    In more recent years their over-riding passion has been for Patagonia, its scenery, plants, culture and people and, with a small group of like-minded friends, they have visited this region on more than 20 occasions. Eventually, they decided to write about their knowledge and experience and the result was two books which were published by the Alpine Garden Society in 2013/4: ’Patagonian Mountain Flower Holidays ’for which Hilary was the lead author and ‘Flowers of the Patagonian Mountains’, for which Martin Sheader was the lead author. Austin was a co-author on both.

    Both Hilary and Austin are keen gardeners and for over 17 years have been living in Somerset – south of the Mendips, where they have a one-acre garden in which they grow a variety of unusual trees, shrubs, herbaceous perennials, grasses and alpines including several of South American origin.

    Michael D. Myers   Dip Hort (RHS), HND, BSc (Hons), MSc, MHort (RHS), CBiol, MSB, MCIHort, FLS, PGCE.
    Michael has had an interest in gardening from an early age and by the time he left sixth form, horticulture was his chosen career. After gaining practical experience at Harlow Carr he studied horticulture at Askam Bryan College, which included a work placement in the alpine department at RHS gardens Wisley. From 1988 to 1991 Michael studied Plant Biology at Leeds University and whilst here wrote ‘A Review of the Genus Hepatica’ for the Alpine Garden Society Bulletin. In 1991 he was the winner of the ‘Young Horticulturist of the Year Competition’. After his degree he completed a Master’s degree in fungal technology at the University of Kent at Canterbury followed by post graduate research on mycorrhizas at Sheffield University.

        Michael worked as a self-employed horticulturist and nurseryman since leaving full-time education, but since 2001 has been a horticulture lecturer for Craven College in North Yorkshire. He was involved in the renovation of the Aysgarth Edwardian Rock Garden in 2002 which was filmed by Tyne Tees who made a two-part programme called ‘The Secret Garden’ in 2003.
        Michael has held three Plant Heritage, National Plant Collections in the past, namely Primula marginata, Anemone nemorosa and Hepatica. Plant hunting trips to see these and other alpine plants in the wild have involved travelling to Slovenia, Romania, Czech Republic, Poland, Cyprus, Corfu, Crete and the Maritime Alps.
        In 2014 he completed the RHS Master of Horticulture which culminated in a thesis on hepaticas, this formed the basis of a further two-part article on hepaticas for the AGS, ‘Enchanting Hepaticas’ and ‘How to Grow Hepaticas’ in 2015. The thesis also led to writing two books for an Italian publisher, ‘Conoscere E Coltivare Le Hepatica’ and a book on snowdrops, ‘Conoscere E Coltivare I Bucaneve’.
        Michael’s garden is occasionally open to the public where visitors can see an eclectic mix of alpines, bulbs, woodland plants and shrubs, including over 500 varieties of snowdrops. He is an enthusiastic exhibitor at AGS shows and has been a member of the AGS since the 1980s.

    Information: I am a retired garden designer and plant nut based in south-east Essex – the driest part of England. I have been gardening in ‘Subtropical’ or ‘Exotic’ style for 35 years and have a special interest in gardening with cacti and succulent plants. This interest has led to much travelling, specifically to Mexico, the home of many of my favourite plants.
    I have written many articles for RHS publications and my own garden has featured twice in the RHS The Garden. My garden also featured on BBC Gardeners’ World in 2017 in addition to, over the years, many newspapers, magazines and books.
    I have been on something of a crusade to promote exotic gardening in general and gardening with cacti and succulents in particular for some years . I regularly give talks to BCSS branches and zone conventions, garden clubs and societies, once having been invited to talk at a seminar in the Algarve on gardening with succulents. I’ve twice given talks to RHS committees.

    Fee: £95
    Home town: I live in Norway, but charge travel from a London base
    Availability: In “normal times” I visit the UK quite often, so it would be possible to pair an in person talk with one of my travels so that the group does not pay my travel expenses from Norway, but only from London.
    Zoom: yes
    Information: I’m a Norwegian gardener, writer, photographer and public speaker based in Norway. I have written several gardening books and appeared on Norwegian radio on several occasions. I run a small nursery specialising in herbaceous perennials and open my plant packed garden to visitors in the summer.
    Over the years I have given numerous talks in Norway and in the last years several in the UK.
    I travel to the UK several times a year, mainly during summer to attend the larger RHS flower Shows, but more and more also during the winter. I also volunteer at The Beth Chatto Gardens for a week every winter to get away from the snow here in Norway.


    1. Growing alpines and woodland plants in Norway. A talk about some of the alpines and woodland plants that thrive in our cold, harsh climate. Anemone, Hepaticas, Anemonellas, Saxifraga, Trillium, Erythroniums. Meconopsis, Glaucidium etc.
    2. Confessions from a Norwegian gardener. About the trials and tribulations of gardening in a country with almost six months of winter. The talk is mainly focused on my own garden north of Oslo and the large selection of plants we can grow in this cold climate, but also the very varied climate here in Norway. Also a short bit about the very short history of gardening that we have in this country, and a few other Norwegian gardens.
    3. Plant propagation. Since I run a small nursery, plant propagation is at the heart of everything I do. This talk is about how I can propagate my own plants (from a private garden owners perspective, not big scale) using methods such as seed sowing, cuttings, divisions, root cuttings and layering, just to name a few. I will also show examples of some of the plants can be propagated using these different methods.

    Information: I’m running a small nursery, specializing rare alpines in the Netherlands. My interest in alpines started about 45 years ago, during my first treks in the mountains and I am particularly focused on the high alpine vegetation, getting fascinated by the beauty of all those wonderful genera like Saxifraga, Androsace, Dionysia and Daphne.My first impulse and challenge was to start growing the most extremely cushion plants. But found out, it was not always easy to realize in my low land conditions in the Netherlands. Together with my wife Mariet we have traveled extensively with trips to many European countries and different parts of the European Alps, Sierra Nevada, Patagonia, Tierra del Fuego, Central and N. Chile, USA, China, New Zealand and Turkey. During several years I organized 9 expeditions to Patagonia. And as a result, got more and more interested in the fascinating vegetation of Argentina and Chile.As a lecturer I was featured on speakers tours in the US with NARGS and in Scotland with the SRGC, and in New Zealand with NZAGS. There were as well, many other lectures in the US, England, Germany, Scotland, Czech Republic, Belgium as well as for our own Dutch Society. Topics included the different cultivation aspects of alpines or presenting travel reports of his expeditions.Recently I was president of the Dutch alpine garden Society (NRV) as well as having served before. Additionally I was the vice-president of the Saxifraga Society in England for about 20 years. As time permits in our nursery, I’m spending as much time as possible in the winter writing articles for the different societies and listening to the baroque music of my favourite composer Johann Sebastian Bach.

    1. Kurdistan:  this takes in various trips around the borders of Turkey, Iraq and Iran including some nice quiet volcanoes. Very high and spectacular mountains with a huge number of endemic plants.  Our favourite region of the World.
    2. The Zagros:  The unbelievably rich flora of this high and very snowy range of mountains which stretch down the western side of Iran and have been quite difficult to access until very recently.  We will show lots of Dionysias as well as some spectacular fritillaries, tulips and the hugely variable Anemone biflora.
    3. Flowers of the Pontics:  A photographic tour which criss-crosses from the moist temperate climate of the Black Sea-facing slopes to the drier high steppes on the south side through spring, summer and autumn.
    4. Georgia in the Early Spring:  We took a short tour to Georgia in April 2010 to see the early flora in both the Caucasus and the Lesser Caucasus so we show lots of Primulas, Scillas, snowdrops and other fabulous woodland flowers.  There were even some early alpines in the snow melt.
    5. The Levant: Hatay to Hermon: this is about spring flowers in the Levant (Amanus in Turkey, Jebl Nusairia in Syria and all ranges in Lebanon). Mainly Mediterranean bulbs with a lot of Cyclamen and some high mountain flora.
    6. Elburz and Kopet Dag: a circular trip around the Caspian forests and then into the dry Kopet Dag via the Golestan National Park. The forests contain a lot of very garden worthy plants. Great Irises and a couple of Dionysias.
    7. Turkish Delights: a more general talk based on 15 trips, over 25 years, throughout the three climatic zones in Turkey and their special plants. The three zones are Mediterranean, high central plateau and the northern temperate rainforest.
    8. Petra to Persepolis: A talk which we prepared for the World of Bulbs IV conference in January 2010. We describe the highlights of the bulbous flora of the mountains which form a huge arc around the Syrian Desert and Mesopotamia from Jordan through Lebanon, Syria, Turkey and Iran ending at the famous city of the Persian Kings near Shiraz.
    9. The Treasures of Tadjikistan & Uzbekistan: We have been plant hunting in Central Asia a lot recently and this is just part of the story.  It starts next to the border with Afghanistan and goes via Samarkand and Tashkent to the Chatkal Range. This is the centre of Tulip and bulbous Iris development and includes many other genera including Fritillaria and Corydalis.
    10. Plant Hunting in Kyrgyzstan & Kazakhstan: This takes up the Central Asian story and moves from the Chatkal, dips back into the Pamirs and then we go through the magnificent Tien Shan on our way up to the Russian border.
    11. The Treasures of Uzbekistan: We visit the western extensions of the Pamir and Tien Shan Ranges which abound with bulbous plants in the Spring.  We also can’t resist taking you to some of the best bits of Samarkand and Shahrizabz with their enormous and spectacular medieval mausoleums. A more detailed talk about this historic region.
    12. Eastern Kazakhstan: Tien Shan to Altai: A more detailed trip to the furthest reaches of Kazakhstan to see the bulbs and early alpines there including several Tulipa, Fritillaria, Iris and Corydalis.
    13. Kyrgyzstan: Land of the Nomads: This small Central Asian state is more than 90% mountainous occupying both part of both the Pamir and the Tien Shan. It has a rich alpine as well as bulb flora and spectacular country. A more relaxed tour through one of the few countries that we really fallen in love with. We have now spent a lot more time there and seen many more exciting things.
    14. Steppes in the Snowmelt: A tour of the northern hemisphere’s high steppes at snowmelt time. This is the time when huge numbers of bulbs and other alpines come rapidly into growth and flower. We visit: California, Morocco, Greece, Turkey and Iran. This is a talk which was prepared specifically for the Chiltern Conference in September 2010.
    15. Autumn in the Mediterranean: A look at plants which flower through October and November in the Mediterranean area. This takes in Spain, Greece and Turkey. Great pictures of Colchicum, Crocus and Cyclamen.
    16. Bulbous Habitats: A look at various habitat types where bulbs are found using pictures from all over the northern hemisphere. We talk about the habitat and how we can copy that to get such bulbs growing in UK.  It can be adapted for either general gardeners who like to grow things in the garden or for more expert audiences who have access to greenhouses and frames and want to learn more about the subject.
    17. Early Bulbs: Having grown and shown bulbs in early shows for the best part of 40 years we review those which, in our hands, normally flower before the end of March in either the garden or in pots.  It shows of many species in wild habitats and how we cultivate them.  We have included a number of medal winners to show what can be achieved.
    18. Maintenance of a Bulb Collection: A detailed, practical review of the way in which we manage our bulb collection in Wales, how we propagate the various genera and how we grow them through the year.
    19. Fritillaries on Four Continents: A review of our favourite genus based on habitat type and therefore cultivation requirements.  This was prepared for the 2011 International Rock Garden Conference.
    20. Wildlings & Foundlings: A short (30 min) talk written for the Galanthus Gala 2012 about some of the more unusual Galanthus in the wild, their habitat & co-inhabitants and some new forms which we have raised.

    All talks are primarily focused on bulbs but we put in lots of other things like wildlife, archaeological sites and even a few people sometimes.

    Garden Talks for a more general audience:
    21. The Garden at Llwyn Ifan: Our garden in the wild wet west of Wales which has developed over 15 years.
    22. Bulbs for the Garden: We specialise in bulbous plants and this describes those that are good garden plants in the west of Wales.
    23. Autumn in the garden:  Our favourite season with autumn colour and lots of flowers.
    24. Alpines in the wild and in cultivation: A general talk (slides) about the “how to construct” and “what to grow” in the way of alpines. We discuss rock gardens, troughs and alpine houses and an A – Z list of good plants. This is where we started way back in the early 1970s and how our interest has developed.
    25. A Plantaholic Home and Away. Rannveig has prepared a talk about how she became a plantaholic at a very early age, how she has been unable to shake off the affliction and how it manifests itself both at home and away on many of our botanical trips around the World. This was first given at the Scottish Bulb Weekend in 2016.

    7. Gardening in a changing Climate. If there is one thing that climate change will bring it is extremes of weather, either heat, drought or wet. Therefore, plants that exhibit a willingness to survive and even thrive under tricky conditions will become increasingly important. However, that doesn’t mean we have to rely on boring Hypericums and Geranium Johnson’s Blue! This talk looks at the consequences of global warming and at beautiful, interesting, more unusual plants that are amenable to weather extremes. New in 2019

    Talks to non-AGS groups: yes
    Fee: £ 25 (Zoom talks) £40 (in-person talks)
    Availability: Most of the talks are in 2 approximately 45 minute sections however they can be distilled into a single hour long talk if enough notice is given and some talks are an hour (please enquire). I’m also happy to try and tailor talks to specific groups as although most talks have lots of cacti and other succulents in them there are bromeliads, tillandsias, orchids etc etc as well as scenery, other plants and wildlife that should appeal to a wider audience. More talks are being added as and when I’m able to travel or put them together! Thanks.
    Zoom: yes
    Information: Ian’s interest in cacti started as a teenager but as so often happens it was interrupted by further education and, in his case, a job in Fiji. On returning to England Ian was able to get back into the hobby and has held various roles in the British cactus and Succulent Society (BCSS) at branch level. His photography has featured in BCSS calendars and in cactus books, and he has also written numerous articles for both the BCSS journal CactusWorld and the Mammillaria Society. Ian has talked widely at BCSS branches and at conventions in the UK and overseas. He has travelled extensively to study and photograph cacti in habitat, as well as the rest of the rich flora and fauna of North, Central and South America and the Caribbean.
    After taking voluntary redundancy Ian took over Eau Brink cactus nursery in Norfolk. Ian is now on the committee of ELK (European Countries Conference for Cactus and Succulent enthusiasts).
