40th Anniversary Year

Welcome to all Clematis Lovers

RHS Chelsea Flower Show 2024 - yet another Chelsea Gold for Raymond Evison

The RHS Chelsea Flower Show, one of, if not THE best horticultural show in the gardening calendar, closed in late May.

Raymond Evison, the founder of this Society, has been exhibiting at Chelsea for many years. I am very pleased to mreport that this year, Raymond Evison Clematis was awarded their 34th Gold Medal. It's an amazing record.

The Society sends our congratulations to Raymond and his team.

Celebrating 40 Years of the International Clematis Society

The International Clematis Society, founded in 1984 by Raymond Evison, is 40 years old this year. As I write this, our celebratory meeting in the Loire in France is about to start. We meet on Friday afternoon, 7th June 2024 in the city of Tours, and finished on Saturday morning, 15th June in Orléans.

Initial details were presented to attendees of the webinar held on Wednesday 28th November. This webinar was recorded and is available on our 40th Anniversary Meeting page. As well as the webinar recording, I have retained the original text, which gives our initial ideas on the itinerary. Please visit Future Events. See also the Fall Newsletter 2023.

I also hope to celebrate this anniversary with a number of special articles in the next journal, looking back on some of our achievements, delving into some of the older journals for hidden treasurers, and getting members old and new to talk about their memories of the Society and looking into the future.

Membership Renewal and Fee Increase

Membership of the Society runs from 1st January to 31st December each year, which means if you haven't yet renewed for 2024, now is the time to do so. Fiona Woolfenden, our Secretary, has been working long and hard, sending reminders to those of you who had not done so, and with very pleasing results. However, there are still a few who have yet to renew. Please do so now.

The Society has found it necessary to increase our membership rates. Ordinary membership, in Pounds Sterling, has gone up by £3, an increase of slightly less than 10%. This is the first increase since August 2017.

Other memberships in Pounds Sterling and memberships in Euros have also been increased by corresponding amounts.

Please note that, for personal reasons and with immediate effect, the Society has withdrawn the facility to pay in Canadian Dollars, Japanese Yen and US Dollars.

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 List for 2023-24 is now closed for orders. We had a great selection of seeds this year - thank you very much to everyone who donated to the Exchange.

The task of sorting and distributing seeds continues, so if you ordered some, please be patient. Orders have to be sorted and seeds allocated. Then seeds are distributed to the country distribution points for onwards sending to members.

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.
