Welcome to all Clematis Lovers.
COVID-19 PandemicThe Society sends our best wishes to clematis lovers all round the world, to their families and their friends. Please take care and stay safe. We salute all those in the essential services, especially health services, for their dedication to duty, often at risk to their own health.
2021 Denmark MeetingThis event, originally planned for July 2020, has already been postponed for one year. However with the continuing COVID-19 pandemic still placing severe restrictions on people and travel, etc., Brightwater Holidays and the Society have agreed the only sensible action to take is to defer the meeting for one more year, to July 2022. An email detailing this decision, and the options current attendees have, has been sent to all attendees. One upside of this is that bookings for this event is open once again, so anyone who now wishes to join should contact our secretary, Fiona Woolfenden.
2021 Seed ExchangeWe are delighted to report that we are running a Seed Exchange again this year thanks to Benedikt Herian, Germany. The 2021 Seed Exchange List was emailed to all members around mid April. It contains full instructions on how to request seed. The list is also available on this website at 2021 Seed Exchange List.
WebinarsWith the restrictions on travel and meetings due to COVID-19 pandemic, the Society has been running a series of webinars (online seminars). We held our fifth webinar on 24th March. Webinar #1, #2 and #4 were for Society members only. Webinar#3 and Webinar#5 were also open to the public. These two attracted audiences of 94 and more than 150 respectively, which pleased all of us, especially since the Society has gained some new members as a direct consequence. As we approach spring and summer, with members wanting to get out in their gardens whenever the weather permits, the Society will pause the webinar schedule. We hope to hold one member-only event over the summer, then run a fuller schedule over autumn and winter, to include one or two member and non-member events. For a link to the latest webinar, please visit our I.Cl.S. Webinars page. Videos of our member-only webinars has been posted on the member-only webinar page. A link to this page was published in the February 2021 newsletter. However, if you've mislaid the link, please email our secretary, Fiona Woolfenden
Recommended ClematisReflecting the wider appeal of what used to be called the "Clematis for Beginners List", a sentiment voiced by many members, the Society has changed the name to "Recommended Clematis". The qualification for inclusion on the list remains unchanged, beautiful, reliable, easy to grow, resistant to common clematis diseases and reasonably available. So now, regardless of your experience with clematis, check out the list, you might find something very interesting. To increase the relevance to all members our thanks go to member, Marie Laure Rauline of Earl Javoy Plantes Pepinieres, for producing a French version of our downloadable Recommended Clematis document. You can find this by visiting Recommended Clematis and selecting the last link on the left hand side.
2021 Delaware Clematis MeetingDue to the COVID-19 pandemic worldwide, the organizers of this independent meeting have regretfully decided to cancel this event. Please see Future Events for a statement from Wim Snoeijer.
The International Clematis Registrar, and the International Clematis Register and ChecklistThe 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 six supplements can be found via the RHS website at https://www.rhs.org.uk/plants/plantsmanship/plant-registration/Clematis-registration/Clematis. 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 ClematisThe 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 ReferencesA 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 CollectionThe 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.
Clematis Nomenclatural Standards List by Wim SnoeijerWim Snoeijer has provided another update to this list, and added a few more images. You can find it at Clematis Nomenclatural Standards List. I've changed the format slightly and the images, instead of being embedded within the list which made it a little disjointed, are now available by clicking on the link to make them appear in a separate window. The list is also available as a downloadable .pdf file. Over the next few months I hope to add many more images, and at higher resolutions than currently displayed. If you are unfamiliar with the concept of Nomenclatural Standards you may wish to read the article by Wim Snoeijer that was published in Clematis International 2010.
Nursery MembershipThe 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 ClematisAn 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.
How do you pronounce .....
If you're uncertain how to pronounce some clematis names, why not visit Clematis on the Web. A number of cultivar entries now have a helpful "how to say" feature.A classic example is probably C. 'Mrs Cholmondeley'. How do you pronounce this? Just take a look at Clematis on the Web - Mrs Cholmondeley, click on the loudspeaker icon and find out for yourself. This is an extreme example but I'm sure there are many others that people may be unsure of, but don't like to ask. Now you can find out in the privacy of your own home.
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!
