The International Maple Lovers Extravaganza

October 28–30, 2022
Raleigh, North Carolina

Join other maple enthusiasts and professionals from across the world who share a common passion for these fascinating plants.


Originally scheduled during 2020 and postponed due to the pandemic, the triennial International Symposium of The Maple Society has been rescheduled to October 28-30, 2022, in Raleigh, North Carolina.

There will be an array of interesting workshops and speakers, covering such topics as collecting maples from the wild, the technical aspects of fall coloration, drone use in microclimate monitoring for long-term conservation, the historical journey of the genus Acer, growing maples from a commercial perspective, and more!


Field trips will be taken to horticultural gems including Duke Gardens, JC Raulston Arboretum, Juniper Level Botanic Garden and Plant Delights Nursery.

Registration is $450 per person, excluding the hotel; a special hotel rate is available with the Hyatt House in Raleigh-Durham (use the Hyatt House Hotel button to reserve).


Our host hotel is the Hyatt House RDU/Brier Creek, located close to Raleigh-Durham International Airport. The Maple Society has negotiated a special rate of $109 per night—not just for the symposium dates, but also for 2 nights pre- and post-conference, should you choose to extend your visit.


October 31 – November 2, 2022

After the Symposium, join us for a separate, 3-day tour of gardens located in and around Asheville, North Carolina. On Monday October 31, participants will board a van or bus (depending on the number of interested parties) which will take us to four different locations, returning to Raleigh by late afternoon on November 2.


Cost for this post-symposium tour is $110 per person, excluding meals and hotel. The Maple Society has negotiated a special rate of $89 per night with the Comfort Suites in Asheville (use the below "Comfort Suites Hotel" button to reserve).

Maples and Climate Change

Zoom Seminar presented Thursday November 4, 2021
Watch This Space for a Link to the Recorded Presentation

As our planet warms and becomes more variable, temperate forests will experience more frequent false springs and droughts. What do these manifestations of climate change mean for the genus Acer?

This seminar was taught by Jake Grossman, Visiting Assistant Professor at Swarthmore College where he teaches courses on ecology, plant biology, and global change biology. His love for the genus Acer was nurtured by a two-year post doctorate fellowship at the Arnold Arboretum where he worked with the Arboretum’s renowned Acer collection.

Come visit this garden and see incredible trees without foliage. Dan has spent more than 20 years working with many of these specimens and his self-taught aesthetic pruning skills have created some beautiful structure. You will have an opportunity to see dozens of mature cultivars that have been groomed for many years.  Dan will share his pruning technique and philosophy while doing a bit of off-season pruning as a demonstration.
