I.E.S. 20th Anniversary Convention in the Botanical Garden Meise Belgium on 24th to 25th May 2025.

Following the very successful convention in the Meise Botanical Garden our Chairman Rikus van Veldhuisen has written a brief resume of the proceedings.

The International Euphorbia Convention in Meise.

On 24th and 25th of May the International Euphorbia Society celebrated its 20 years existence in the ‘Nationale Plantentuin’ in Meise Belgium. Nearly 100 lovers of the plant Genus Euphorbia gathered this weekend in the idyllic castle lying centrally in the beautiful scenic landscape of the botanical garden. Although many of them came from far distances, many of them are friends for many years, or at least became friends this weekend. During the whole weekend there was plenty of time to meet and catch up, but in the end it seemed there was still not enough time.

On both days two talks were held and every single talk got ample attention and a lot of credits. This was not surprising as the auditorium in the castle, made available by the ‘Nationale Plantentuin’ for free, is very well equipped to host such an event.

Another highlight of the weekend was of course the visit to what I think is one of the best and largest collections of succulent Euphorbias worldwide, normally not open for public. It is in fact so large that the visitors in the greenhouses were hard to find when walking in between the tables, loaded with the many plants, sometimes over 3 meters tall.

In the opening talk of Marc Reynders, the Scientific Manager of Greenhouse Collections, the importance of the collection was highlighted. The goal is not only to keep a species of Euphorbia in the collection, but the genetic variability needs also to be secured for the future. A lot of succulent Euphorbias are highly threatened in their existence in nature. If a species can successfully survive in cultivation or in a seed bank in the genetic variance, successful re-introduction in nature is possible when a species might go into extinction. This task taken on by the ‘Nationale Plantentuin’ will become more and more important in the future.

It was in no time the weekend was already history and based upon the members asking when it will be held the next time, it was a great success. I look forward to the next convention as I am sure you will also.

NEW in October 2024

Membership Renewals

The years 2022 and 2023 were rather unusual for the society as due to extenuating circumstances we were only able to produce 3 issues to Volume 19 of the societies journal “Euphorbia World”. 

Subscriptions were suspended for the year 2023, but we are happy to say that membership is now open again as normal and subscriptions are able to be taken using the link on this site. For all the existing members we hope you will continue to subscribe and hope that we can gain many new members also.

However it has been decided after much discussion between the committee members that it has been necessary to increase the subscription rates for membership of the Society. This decision was not taken lightly but bearing in mind that the subscription rates have not been increased for many years and the Society has had to absorb many increases in postage and printing costs it was deemed that this increase was inevitable to ensure the the Society could continue to provide the quality of the Journals. The new rates are reflected on our membership page and come into effect immediately.
