Protecting WNC’s Rare Pinkshell Azalea
We recently went on a unique collection trip with Carson Ellis, the Native Azalea Collection Coordinator at The North Carolina Arboretum. The goal was to document and collect seeds from rare, native azaleas on Conserving Carolina’s protected lands, ensuring the long-term survival of these beautiful species.
This work is part of a crucial conservation effort to safeguard the genetic diversity of North America’s native azaleas (deciduous Rhododendron species).
A Treasure on Conserved Land
The focus of our recent trip was the Pinkshell Azalea, Rhododendron vaseyi. This species is a narrowly distributed endemic, meaning it naturally occurs only in specific, higher-elevation areas of Western North Carolina. Due to its limited range, it is tracked by the NC Natural Heritage Program.
The success of this collection is a testament to the long-term value of conservation. The property where we found the azaleas was protected by a conservation easement in 2015, primarily to safeguard the water quality of the Cathey’s Creek Watershed in Brevard.
As part of the protection process, an ecological report—submitted by senior plant ecologist and Conserving Carolina board member, Owen Carson—identified the rare azalea population. This data later enabled Carson Ellis to connect with our Natural Resources Manager, Torry Nergart, and successfully locate and tag the flowers this past spring, leading to our recent seed collection.
The Power of Compounding Conservation
While the initial goal of the easement was water protection, its ultimate value is far greater. Our stewardship team embraces the idea that conservation is not just cumulative—it’s compounding. By protecting the land, we open the door to further research, preservation, and scientific collaboration.
In fact, this partnership has already yielded more success:
- The team also collected seeds from a significant population of the Flame Azalea (R. calendulaceum) on the property.
- A third species, the Smooth Azalea (R. arborescens), was documented, further underscoring the rich biodiversity protected on the site.
Safeguarding Wild Genetics for the Public
The process of collecting these wild-type genetics is critical for conservation. The collected seeds are meticulously documented and then split among three different facilities for maximum security: The NC Arboretum, the NLGRP (National Lab for Genetic Resource Preservation), and the Mills River Horticultural Crop Research and Extension Center.
These seeds are not just banked, they are put to work:
- Public Display: Seedlings are grown for eventual outplanting into the Arboretum’s 8-acre Native Azalea Collection landscape.
- Vaseyi Trail: The specific R. vaseyi plants collected will become a central part of the Arboretum’s planned new exhibit, the Vaseyi Trail, where the public will be able to see and learn about this local treasure.
We are excited to see the genetics of this local population of Pinkshell Azalea represented in a major national conservation collection. This successful partnership with The North Carolina Arboretum highlights the value of conserved land in serving as vital natural repositories for our region’s most precious flora.
