Webinars
Welcome to the Society Webinar videos. The first of these was held in September 2020, at the start of the COVID-19 pandemic, when it was clear normal meetings would not be possible for some time. They have proven so popular that the Society now holds several each year. Most are for Society members only, but one or two each year are open to the public. In the latest public webinar, Webinar #2603, Linda Beutler, renown clematarian and Curator of the Rogerson Clematis Garden, Oregon, gave a wonderful presentation titled “Clematis Will Rock You”, discussing clematis that can, and often should, be planted within a rock garden or similar environment. Although you can usually only view the recording of the latest public webinar on this page, the Society has agreed to retain the recording of another public webinar, Webinar #2601. Held on 25th January 2026, this webinar was given by Wim Snoeijer, clematis breeder, expert and enthusiast from the Netherlands. Titled "Key to the Classification of Clematis Cultivar Groups", it describes how, by observing specific growth characteristics, one can identify the group to which a cultivar belongs. The helps to decide where to plant it, what conditions will it like, when/how/if to prune it and how to treat it. It can also be useful when trying to identify an unlabelled cultivar. Wim suggested that his two-page key would be useful for attendees to have on hand during the lecture, and it was made available as a download from the Society website. If you want a copy, you can find it at Two-Page Key. If you joined either of these sessions live, you still may want to replay one or both in case there were some things you missed. If you were unable to join either original screening, now if your opportunity to learn from experts. Webinars are run using Zoom software, available on most platforms. It is free for individuals to download and install. Although you should not need to install the software to participate in future events, it may make life easier. You shouldn’t need any special software to view this recorded webinar as it is stored in the near universal "mp4" format. Once you're finished, click on the link at the bottom of the page to return to the International Clematis Society homepage.
