Welcome to all Clematis Lovers.
Clematis International 2019The Journal for this year is progressing well. It is currently being proof-read by my small band of dedicated helpers. This is a intensive and tiring task and I am indebted to those who do it. I am not sure whether it will be published before the Meeting and Conference in the USA in the middle of June, but I am fairly optimistic. The Journal is only sent to members who have renewed their membership for this year, so perhaps you'd like to check that this doesn't apply to you. Reminding members to renew their membership is a lot of extra work for us, so if you are one of these, please renew now.
2019 Seed ExchangeThe 2019 Seed Exchange is now closed. We thank Wim Snoeijer for his hard work managing this valuable membership facility, both for this year and all the previous years that he's done this job. As has been said in the Newsletter, Wim is retiring from this role and the Society is looking for a replacement. If you might be interested, please contact our secretary, Fiona Woolfenden.
Portland 2019 MeetingYou only have until 15th May to register for our meeting and conference in Portland, Oregon, USA. After that we must close the attendee list as we must confirm numbers with the various suppliers. However as a final incentive, the $100 late registration fee on whole week registrations has been withdrawn. So you still have time to join in, but ONLY JUST. Please see Future Events page.
Delaware/Columbus Clematis Meeting, Ohio, U.S.A., September 2020Following the success of the Clematis Meeting & Chantilly Flower Show in October 2018, a meeting will be in the USA in September 2020. You will find details, including dates, on our Future Events page.
RHS Clematis Register and ChecklistI am very pleased to inform you that The International Clematis Register and Checklist 2002, which went out of print some time ago, is now available in electronic format that allows text searching. Our congratulations and thanks go to Duncan Donald, current International Clematis Registrar, and those others involved in this task. 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 varieties 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 section. Once you've filled it in and signed it, please send it to Duncan Donald, the International Clematis Registrar.

Clematis for Beginners ListThe Society's Clematis for Beginners List gives a list of cultivars that are very suitable for clematis novices around the world. It was reviewed and revised during our meeting in Devon and Cornwall in 2015. It has been available online for a few months and also as a downloadable version from our Clematis for Beginners Download section. Recently we have added a German language version to the English and Dutch issues, thanks to Heidrun Kläser. 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, I'm afraid) folds into a handy booklet, 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. Initially it covers the years 2005 - 2010 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, about 290 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. Now Duncan Donald, International Clematis Registrar, has 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. Duncan is waiting to clarify where further donated catalogues should be sent. As soon as he has this information I will publish it 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!
