Spring arrives with questions: how much should I prune back a clematis in a container? Is it time to replant it completely, and if yes, what are the steps? How do I fertilize and refresh the clematis for spring? All of these questions will be answered in this demonstration class with clematis curator Linda Beutler. This class covers clematis already planted in containers. There will be another class later in the spring about potting up a new clematis in a new planter. Comparison plant suggestions for clematis in containers will be discussed in both classes (selection, when to replace, adding new plants to an old container).

Instructor: Beutler

Registration is CLOSED for this class

Clematis will Rock You: The best clematis species and cultivars for rock gardens

Join the Zoom presentation by FRCC Curator Linda Beutler to the Delaware Rock Garden Society, a chapter of the North American Rock Garden Society (NARGS). For more information, visit Delaware Rock Garden Society Events. Open to non-members.

Wim Snoeijer from The Netherlands will do a presentation about Clematis Cultivar Groups. There have been many classifications proposed and published since the book The Clematis as a Garden Flower by Moore & Jackman in 1872. Wim will briefly address the history of classification for clarity. The main focus of his talk is to explain the Clematis Cultivar Groups that he developed and applied throughout his Clematis career, using the key he created. Wim suggests that the two-page key would be useful for attendees to have on hand during the lecture. It can be downloaded at:
https://www.clematisinternational.com/260125-wim-snoeijer-clematis-cultivar-groups-key.pdf

Wim’s 35 years of experience in breeding clematis began in Boskoop using the clematis collection of Jan Fopma and continued while he was working as a clematis breeder at J. van Zoest B.V. nursery. Through crossbreeding clematis, he learned the relationships between plants and between groups of related plants and developed his Clematis Cultivar Group Classification system.
