I remember the first time I saw the largest Rhododendron Maximum tree. I had recently moved back to Pennsylvania, and I was driving on 422 towards my parents’ house when I looked to the left and did a double-take! An enormous Rhododendron, in bloom, at least 40 feet across and 20 feet high was in full bloom. And, it was dwarfing the house it was growing next to. After doing a little local research, I learned about how famous this rhododendron has been in our region. Ever since then, each time I pass, the Rhododendron and I exchange a little greeting.
As someone who lives in the Allegheny Mountains, Rhododendron has a special place in my heart. It is one of the dominant understory trees (and yes, it often is the size of trees here!), growing both in deciduous and conifer (Hemlock) forests, encrusting rivers, and streams, and adding so much beauty to our land. Often confused with Mountain Laurel (see this PDF for some differences), Rhododendron is part of the Laurel-Azalea-Rhododendron group of plants in the Heather family (Ericaceae). Rhododendrons can be found throughout the world and have some key distinguishing features. I’m focusing my attention today on the Rhododendron Maximum species, which is also known as Great Laurel, Great Rhododendron, Rosebay Rhododendron, American Rhododendron, Bayis, Late Rhododendron, or Big Rhododendron. If you don’t have Rhododendron Maximum, you can substitute any number of other Ericaceae species such as Mountain Laurel, another Rhododendron variety (including ornamental), or Azaela. Many people have these shrubs growing already as ornamentals in their yards or local towns if they don’t have them in the wild, making this a good plant to work with not only for those in the Appalachian mountains but those in suburban and urban areas.
This post is part of my Sacred Trees in the Americas series. In this series, I explore the magic, mythology, herbal, cultural, and divination uses, with the goal of eventually producing a larger work that explores many of our unique trees located on the US East Coast. Other trees in this series include Witch Hazel, Staghorn Sumac, Chestnut, Cherry, Juniper, Birch, Elder, Walnut, Eastern White Cedar, Hemlock, Sugar Maple, Hawthorn, Hickory, Beech, Ash, White Pine, Black Locust, and Oak. For information on how to work with trees spiritually, you can see my Druid Tree Working series including finding the face of the tree, communicating on the outer planes, communicating on the inner planes, establishing deep connections with trees, working with urban trees, tree energy, seasonal workings, and helping tree spirits pass.
Ecology and Growth
The Great Rhododendron grows within most of the Appalachian Mountains, although the dominance and size can vary greatly. It spans from eastern Georgia to Nova Scotia, and I will say, it is particularly dominant and amazing here in the Allegheny mounts of Western Pennsylvania. Here, you can see it as a small shrub, 8-10 feet high, and up to enormous sizes. Rhododendrons can grow to 25 or 30 feet tall, twisting, beautiful, and magical. Their waxy simple leaves are evergreen, offering color and vibrancy year-round. In June, they bloom with beautiful pink clusters of trumpet-like flowers that provide a fantastic nectar source for bees, moths, wasps, and hummingbirds. This is why they are planted so widely as an ornamental–because they are truly stunning.
The leaves on the Rhododendron appear almost tropical. They vary from 3″ to over 8″ in length on older branches. They grow in a spiral pattern starting at the top of the branch and spiral down the branch, demonstrating the sacred geometry present in this lovely tree. Like other conifers, Rhododendron will drop and regrow a small number of leaves each year but stay green year-round.
In the wintertime, when the temperatures drop well below freezing, the rhododendron drops its leaves straight down and curls them up so that they look like long tubes. This prevents the leaves from suffering cold damage. As soon as the temperatures warm up, the rhododendron unfolds its leaves and spreads them to the winter sun. This shows incredible resilience and adaptability. One of the ways the hillbillies here in Western PA know it is “damn cold out” is by looking at the Rhododendron leaves!
Rhododendrons particularly like to grow along the edges of streams and are found in both deciduous oak-hickory overstory forests and also in Hemlock/white pine forests. It particularly enjoys wet areas, so you can often find it along riparian zones (particularly on the edges of smaller and medium-sized streams) and also in places where we have rocky outcrops, ravines, and hidden springs. Rhododendrons are usually kept in check by a thick overstory. There are cases where logging or other disruption of the overstory will allow the rhododendrons to spread for acres and acres–I once hiked through a few miles of one such situation in New England and it was quite an experience.
Rhododendrons to provide two important ecological functions: because of where they grow, their deep roots perform excellent soil and erosion control. Because they have large leaves that are evergreen, they also provide excellent shelter–particularly winter shelter–to a host of birds and small mammals.
The rhododendrons also grow in a very whimsical way–they grow twisted, branches coming out at odd angles, and sometimes growing down and back up again. I have long been a whimsical nature artist, and their whimsical, twisted, spiraling branches and trunks have always been an inspiration for me for my own work.
The Rhododendron, as an understory species, does not grow particularly large and thus, has limited use as a wood product. In fact, none of the books and resources that I currently use to research this series, none covered Rhododendron.
And yet, as someone who has worked with this wood, both to carve and burn, I am delighted to say that it is a wonderful wood. I seek it out for my artwork because it is just perfect–not as hard to work as oak or hickory, it has a softness similar to maple or tulip poplar. It has a rosy, soft texture, which is excellent for doing precise woodburning and carving. It has a very consistent light rose color from the thin bark to the core. I like to turn it into wands, staves, and most especially, create necklaces from slices. When I am kayaking out here on local streams and lakes, I look for recently dead rhododendron pieces for this work.
In the woodworking community, you’ll find other people posting about their experience in using it for wood carving, woodturning, and other fine wood products. One of the features of this wood that is often lauded is that it rarely cracks as it dries. The bushcraft community also uses this to make very fine charcoals for a variety of purposes. One of my future plans is to make charcoal and see how it works for art–my choice has been grapevine or willow for a number of years, but I suspect this may also work great.
One of the big debates about using Rhododendron is that the leaves and flowers contain grayanotoxin, which can be fatal if ingested. All evidence suggests that while the greenwood is toxic, the dried wood is fine to burn and to use (here is one such analysis). If you are going to do woodburnings or anything else, because of the plant’s toxicity, I do suggest that you invest in a soldering smoke absorber–these are very inexpensive and can filter out any smoke you may have concerns about.
Beyond the wood, I am unaware of any other uses. This is in part because Rhododendron (along with Azelela and Mountain Laurel) is poisonous, and thus, they do not have any herbal uses. When a plant does not have herbal uses, I have found it also often does not have magical ones, at least recorded ones. I have not found any lore or stories associated with this species, despite its critical importance and dominance in the ecosystem.
Divination and Meanings
Like some of my other overlooked understory plants, there isn’t a lot to go on without any magical or folklore traditions surrounding Rhododendron. Despite this, the ecological aspects themselves offer us some key insights. In particular, I think Rhododendron teaches us lessons about how to thrive in adversity and how to make the most of more difficult situations. While these are lessons that are always appropriate, they are particularly useful now.
Adaptability and Opportunity. As I recently wrote, there is a wide range of plants that thrive in the understory and that thrive in the cold and dark months when the overstory is bare. Rhododendron is one of these plants, demonstrating adaptability, resilience, and opportunity. Rhododendron offers a clear message: in times of dark and cold, find a way to grow, to thrive, and to make lemonade from lemons!
Sheltering in the extremes. The winter leaf foliage of Rhododendron takes the opportunity to spread wide when the warmer winter temperatures are present. However, when the temperatures go freezing, Rhododendron drops her leaves and curls the leaves up tightly to prevent frost damage. This adaptability, combined with shelter, is a powerful healing message. There are times we need to shelter, but we should only do so when the conditions warrant it. After a blast of sub-arctic cold and wind, it is ok to curl up tightly. The key is to remember to uncurl when the situation changes.
Growing your own way. Rhododendron is unlike anything else in the ecosystem here in Pennsylvania. It teaches us the power of individuality and growing in whatever whimsical and beautiful way you want. Rhododendron reminds us to be whoever we want to be. And we can do that regardless of the circumstances that are affecting the outside world. What a powerful and potent lesson for 2020 and beyond!
