EAS summer event: EAS Social Kew

We are excited to finally reveal to you our next summer event. Join us Friday 8th of July in London, UK, where we will explore one of the most famous gardens of the world: Kew Gardens! With beautifully curated greenhouses and outside gardens, this botanical garden is a must-see for all plant-lovers. Their tropical and temperate aroid collections are among the most diverse in the world, with many Brazilian and Asian taxa. Normally closed, Kew will even open its nursery greenhouses to EAS members for a special peek in the private aroid collections.

This event is only open to members.

Note: Partners are welcome, but need to be paying members of the EAS and need to sign up for the event too.

See here for more info or click the banner!

We are pleased to announce our new pin to add to your collection! Make sure to sign up or renew your EAS membership, as you will receive one of these beauties in the mail! Starting now, we will reveal a new collectible pin every year. Missed out on our original pin? The old pins will still be available in our shop (while stocks last). Our first year has been a great success with over 700 aroid aficionados from all over joining us to share the passion of the aroid family. Want to be the first one to hear about new events, articles and talks? Join or Renew today!
 
About the pin:
Kindly designed by Min Lee for the EAS, it features the little-known aroid Gearum brasiliense, found only in Brazil. It’s a seasonally dormant tuberous geophyte occurring in annually flooded savannahs. The large spicily scented blooms appear before the pedate leaves emerge. The species was first collected in October 1828 by William J. Burchell, although the exact locality remained unclear. In 1996 Josef Bogner using, as it turned out, an inaccurate interpretation of Burchell’s fieldnotes tried to locate Gearum but failed. Then, a few years later a specimen collected in 1978 but for decades mis-filed as a Xanthosoma, was located in a Brazilian herbarium and based on this new information Josef was able to bring living plants into cultivation for the first time! The story about Gearum perfectly encapsulates the inexhaustible passion for aroids Josef Bogner had, with the pin serving as an homage to him as the greatest modern European aroider, one who is dearly missed.
 
Note: The pin is also available for purchase in the shop.

EAS turned 1 on June 27th! We reached over 700 members and feel so grateful for this enormous support from aroid enthusiasts all over the world! We have managed to organise 3 in-person events as well as a few online lectures in the past year, and this is only the beginning. The future holds many more events across Europe, opportunities to meet and share and learn from each others experience. Don’t hesitate to get in touch with us for any comment or any idea that you would like to share with us, this society is yours before anything. Thank you all. We look forward to hearing from you!

Don’t forget to renew your membership to receive the new membership gift!

On The Ledge podcast episode
A few weeks ago, our Honorary President Peter Boyce was invited on the popular On The Ledge podcast by Jane Perrone. In episode 193, Peter talked with Jane about our newly-formed society and what aroids are. Moreover they discussed how to mature climbing aroids on wood, some exciting new taxonomic insights and featured a very special vanilla-smelling aroid from Borneo.

An exciting first event!
On Saturday July 17th, it was time for the first of our aroid talks. None other than our Honorary President, Peter Boyce, guided us through the jungles of Asia in search of aroids! You can rewatch the talk here!

Peter Boyce (1964) is an aroid botanist who, together with his wife Wong Sin Yeng, has dedicated the larger part of the last two decades to understanding the taxonomy of enigmatic Asian aroids, describing hundreds of new species in the process. Not only a renowned scientist, Peter is also a skilled nurseryman and takes care of their scientific collection of 3000 living plants on Borneo, most of which are grown no where else in the world!
