40th Anniversary Year

Welcome to all Clematis Lovers

Celebrating 40 Years of the International Clematis Society

The International Clematis Society was founded in 1984 by Raymond Evison, which means we are 40 years old this year. Our 2024 meeting, which took place from 7th June to 15th June, was based in the Loire Valley and was the first meeting that the Society has held in France. We started in the city of Tours and finishing in Orléans, with an intermediate two nights in the city of Loches.

The Loire Valley is famous primarily for the chateaux that lie along the length of the river and we visited quite a few. Whilst many of the chateau gardens are in the formal French / Renaissance style, there are various other designs, including my favourite, Villandry, where the bulk of the planting consists of vegetables and fruit.

On our final day we visited Javoy Plantes, also founded in 1984 and therefore celebrating their 40th anniversary. Javoy is a family business which has grown from small beginning to now be the French leader in the production of clematis and one of the major players in climbing plants in Europe. We were given an extensive tour of the nursery, after which our coach took us to the house and private garden of Marie-Laure Rauline who, with her brother, Benoit Javoy, runs the nursery. We were treated to wonderful and very French celebratory food and drinks in honour of the two anniversaries.

I will be writing my usual set of informal reports on the activities of the meeting, with the first report coming next month.

Membership Renewal

Membership of the Society runs from 1st January to 31st December. Although we are half way through the year, there are still a significant number of members yet to renew for 2024. Fiona Woolfenden, our Secretary, has worked long and hard, sending reminders to those of you who have not yet renewed for 2024 and she has had good success. But this takes a lot of time and effort. So if you still haven't renewed, please either do so now or at least tell us that you don't wish to, so that we need not spend more time than necessary.

You can see the rates and methods of payment, including links to our PayPal buttons, at How to Join or Renew your Membership.

Members Seed Exchange

Our Seed Exchange for 2023-24 is now completed. We had a great selection of seeds this year - thank you very much to everyone who donated to the Exchange. Orders were received earlier this year and all seeds requested have been distributed to Members.

Our thanks to the Society's dedicated team that cope with inspections, certificates, customs and postal delays to achieve this! Many, many thanks to Mike Miller, Guy Opie and Ingrid Kastell.

The seed list, Seeds 2023-24, remains on this website for reference purposes only.

The International Clematis Register and Checklist 2002 - Seventh Supplement

This latest supplement to the International Clematis Register is now available online. In line with the continued expansion of internet usage and with an eye to reducing paper usage and cost, it is suggested that you download it for free from the RHS website, just visit

International Clematis Society on Social Media

The Society has a presence on the social media platforms, Facebook and Instagram. On both of these you will find updates on what's happening in our garden in the UK as well as clematis news from other members. All you need do is click on either of the two logos below.

The International Clematis Registrar, and the International Clematis Register and Checklist

The International Clematis Register and Checklist 2002, which went out of print some time ago, is available in electronic format. One benefit of this is that it allows text searching.

Details for The Register and all seven supplements can be found via the RHS website at However because of the file size of the Register itself, approximately 25 Mbytes, it cannot be downloaded from the RHS web site in the same way that the supplements can. To help the RHS and reduce their workload, Society members wanting a copy should email Ken Woolfenden, I.Cl.S. Webperson and Editor, at icls editor, who will return a download link.

The Society fully endorses the work of the International Clematis Registrar, The International Clematis Register and Checklist 2002 and the six supplements published so far. We recommend all clematis lovers use the standards they describe.

There is, of course, still a need for all Clematis breeders, both professionals and amateurs, to register your Clematis cultivars with the Registrar to continue to keep the International Clematis Register up to date. If you want a copy of the form, information about it is available at the Clematis Registration Form.

Recommended Clematis

The Society's Clematis for Beginners List is now Recommended Clematis, reflecting the wider usefulness of this set of clematis cultivars for all clematis growers around the world. It was reviewed and revised during our meeting in Devon and Cornwall in 2015. It is available online and also as a downloadable version from our Recommended Clematis section, in Dutch, English, French, German and Swedish.

All the clematis on the list are easy to grow, easy to look after and resistant to common pests and diseases, and whilst there are no absolute guarantees where gardening is concerned, most people should have success with all of these.

Because space is not so much of a problem, the online version of the list now contains more information about each clematis featured within it, along with a simple menu bar to let you see each group and then pick the clematis you're interested in. The downloadable version (no illustrations as yet, I'm afraid) is very suitable for taking with you when you visit your local nursery or garden centre!

Journal Index of Clematis References

A reminder of a facility which I'm sure many of you will find most useful - an index of references to all the clematis mentioned in the journals of the Society, both in the text and as pictures. I am indebted to Ton Hannink for all the work he has put into producing the first issue of this index. The index currently covers the years 2005 - 2014 inclusive. Further years will be added as they are completed. Whilst it is quite a large document, some 29 pages, it is not a particularly large file to download should you wish, just under 220 Kbytes. You can find it by visiting the Previous Journals page.

RHS Clematis Catalogue Collection

The Royal Horticultural Society of Great Britain holds a collection of Nursery Catalogues and have been keen to add to it. A number of years ago the Society was asked to canvas our members for any Clematis Nursery catalogues which they had and would donate to the collection, which we did. Quite a few have been donated so far.

Whilst he was the International Clematis Registrar, Duncan Donald extracted a list of catalogues from Clematis Specialists which are currently within the collection and a list of catalogues which feature clematis, but under such headings as "climbing plants" or "climbers". You can find them at RHS Clematis Catalogue Collection and RHS Climbers and Climbing Plant Catalogue Collection. Links to both these files can also be found via the "Information, Answers and Questions" link on the left of this page.

The Society has asked where further donated catalogues should be sent. As soon as we have this information it will be publish here.

Nursery Membership

The Society offers a second category of membership - Nursery Membership. So far we have been very pleased with the support that many nurseries have given by renewing as Nursery Members. We thank them all.

These Nursery Members can be found on a special Nursery Members page on this website.

The Society hopes you will recognize that, as members of this Society, these Nursery Members have a particular interest, knowledge and love of clematis and can be expected to provide a range and quality of plants, and informed knowledge, not usually available in non-specialist outlets. Please check this page regularly for additions.

Whilst it is now too late for your nursery details to be included in Clematis International 2011, any further Nursery Memberships will be published on this website as they are received and also in the List of Members when it is reissued at the beginning of next year.

Trialing New Clematis

An example of a Clematis Trial contract, mentioned in the article in Clematis International 2008 about trialing new clematis by well-known clematis breeder, Wim Snoeijer, can be downloaded by visiting the A.O.B. (Any Other Business) page accessible from our Information, Answers and Questions section.

General Data Protection Regulation - GDPR

This Regulation applies to all organizations, large and small, that store personal data of EU and UK citizens electronically.

A draft Privacy Policy was drawn up and discussed at a previous Council Meeting. We are still working on modifications and amendments. Once completed and the resulting document is agreed by your Council, it will be released to all members and posted in this website.

The Society is committed to complying with this regulation. Should any member have any questions or concerns regarding it, please contact our designated Data Controller, Ken Woolfenden.

And finally ....

The ethos of the Internet is to be an open forum for ideas, views and opinions. Sites should encourage visitors to link to other sites, it's a two-way process. So if you've got a few moments, why not look at our Clematis Links page and follow up one or two. You may find a lot more than you were expecting!
