In early April 2017, Westonbirt’s Dendrologist, Dan Crowley, will be setting out on an exciting documenting expedition to Vietnam, thanks to funding from the Friends of Westonbirt Arboretum. Together with colleagues from the University of British Columbia Botanical Garden (UBC) and the Institute of Ecology and Biological Resources, Dan will be exploring the Hoang Lien Son Mountains, Sapa Province in northern Vietnam, and working to document the Acer species in the area.

About Hong Lien Son National Park

Vietnam as a whole is an area of extraordinary biodiversity (though until recently it has been little explored by plants experts), and the Hoang Lien Son range, a southern extension of the Himalayas, is a particular hub of plant diversity. The national park is home to over 2000 plant species, including some incredibly rare taxa! The area is of particular interest to us here at Westonbirt, as plants from the region have been shown to be hardy in UK cultivation, and we have some examples growing in the arboretum.

What are we looking for?

There is a diverse range of Acer in the region, and in recent years new taxa have been discovered. One of Dan’s chief aims on his travels will be to further define these new Acer taxa, and to perhaps make some exciting new discoveries!

What are we hoping to bring back to Westonbirt?

The information Dan gains on his trip will allow us to expand our knowledge of Acer and help us to better care for and curate the examples currently growing at Westonbirt. His work documenting the species in the area will provide a better understanding of what is currently growing in the region, and therefore will help to form conservation objectives.

We have a number of taxa at Westonbirt Arboretum that are found in the Hoang Lien Son mountain range. A taxon in the Acer pectinatum complex can currently be found thriving in Silk Wood, and an Acer pictum now growing in the Old Arboretum was collected in the area. This last one is particularly exciting as this taxon was not previously thought to be found in Vietnam; Dan will be working on establishing its exact status!

Watch this space for more information on the trip, as Dan will be sending us updates, highlights and photos from his adventures!

Tree of the Month March 2017

What is the Tree of the Month?

Prunus hirtipes

Prunus hirtipes
Why is it tree of the month?

Although its beautiful pale pink flowers are short-lived, they are not to be missed. Produced in abundance, they are a welcome sight as winter turns to spring.

The tree was introduced by the great Ernest Wilson in 1907, who collected it in China, where it is native. Like many trees from that part of the world, it grows happily at Westonbirt, and the young plants are particularly vigorous!

Where can I find it?

The Prunus hirtipes can be found in several spots around Westonbirt: Shop Window, the Cherry Collection and on Waste Drive. Find the plant using the Westonbirt map.

Tree of the Month: February 2017

What is the Tree of the Month?

Rhododendron moupinense

Rhododendron moupinense


Why is it tree of the month?

One of the first rhododendrons to flower at Westonbirt, Rhododendron moupinense is a shrub native to western Sichuan in China, where it often grows as an epiphyte. The parent of our plant was just 30cm tall when seed was collected from it, though our plant is considerably taller than that now and also has rather attractive bark.  Flower colour of the species is somewhat variable, though our plant is distinctly white in this respect. The colour show provided by our other rhododendrons is not so far away…


Where can I find it?

Our sole specimen can be seen growing well just inside Spring Gate in the Old Arboretum. You can locate specimens using the Westonbirt Map.

Living with trees

January 20th, 2017

It’s wonderful that Westonbirt Arboretum is a place where 500,000 people come every year to escape the stresses and strains of everyday life. As part of our Heritage Lottery Funded project we’ve successfully introduced a community programme, part of which enables us to provide some focused engagement with members of the community who are learning to live with a range of mental health conditions. Being from the community ourselves it should be no surprise that we, the staff who work here, also experience many of the same emotions and conditions as the people who visit us. Here, one of our number, Tomas shares his own journey with depression in the hope that his experience may help others…


Living with Trees

Tomas Dewey, Arborist at Westonbirt Arboretum

I am 29 years old, male, and I am an Arborist at Westonbirt Arboretum. I have suffered from Depression since I was 13 years old. When I was 18 years old, without leaving a note or telling anyone where I was going I drove my car to a motorway bridge in the middle of the night and climbed over the railings. It was the thought of my parents’ grief that caused me not to let go. I had attempted suicide, and failed.

It’s sometimes very difficult to explain to someone who does not understand quite what depression is.

One of the reasons it is so difficult is that most people have a preconceived idea of what depression is. I would wager that you could probably remember a time in your life when you have described a particularly dreary Monday morning in winter as depressing. Or described yourself, or others as depressed during a period of sadness or frustration. In reality, Depression is a debilitating and potentially fatal illness. It is a startling fact that in 2014, 6122 people from the UK committed suicide, of this number around 75% were male. But most shocking of all, for males under the age of 45 – suicide is the most common cause of death. If you are reading this and you are a male under 45; you are the thing most likely to kill you. And it’s because we, as men aren’t talking about it. Arboriculture is one of those stereotypical ‘macho man’ industries and so, works as the perfect way of describing the problem, with us blokes that is, causing the dreadful statistics I mentioned earlier.

I just cannot imagine descending down from a 30m pine after a hard afternoon’s slog. As a combination of sweat and dirt pours down my face. Packing up my climbing harness, and putting my chainsaw back in the truck whilst attempting to brush the sweat soaked sawdust from my arms and t-shirt. Before then turning to a colleague and saying,

“Last night I sat in my car, in a McDonalds car park and cried for the best part of four hours because I really don’t want to exist anymore. And I’m trying but I can’t find anywhere I want to be more than nowhere at all.”

I can’t imagine saying that because I don’t want anyone to think I am a ‘wimp’ or a ‘girl’. As well as that I don’t want to impose my weaknesses on them. In spite of knowing I am in the rare but lucky position to have a supportive and understanding team around me, I still struggle to overcome that age old stigma that a Man should be a Man. Brave. Unafraid. Strong. The societal expectation that I should be able to pull myself together and just get on with it. After all, isn’t it common knowledge that sitting down and chatting about your feelings is something that only Women do? Come on, Man up!

‘Manning up’, however does not help. It only aids to make things worse. It adds to the stigma. It reinforces the ideals that keep us quietly pretending to be ok. The reason why I am writing this is because I want to be able to be honest. The proof of how successful I will be in this endeavor will be if my name is included in the title.

But, I should talk about trees. Aren’t they just amazing? Depending on your level of interest, trees can be seen as giant, complicated organisms or as just something beautiful to look at, or both. They’re capable of feats of engineering greater than anything man has ever created. For example, to achieve the remarkable efficiency of photosynthesis trees employ quantum superposition, a fundamental principle of quantum mechanics. Physics aside, they can be used practically. Tree lined roads reduce the likelihood of speeding. In urban areas they can increase property prices and an area’s desirability so much so that new housing estates often name roads after trees to make up for the lack of them. They provide us with the oxygen we need to breath and to neatly tie us back into the theme of the article, they can help aid recovery from depression. There is a simplicity about trees that is quite wondrous. They are calming. If you happen to find yourself away from the bustle of your busy lives and find the time in spring to lie beneath a tree and look up through the branches as the sunlight works its way through the fresh leaves, then you are experiencing something the Japanese would call komorebi (木漏れ日). A word that has no direct translation into English.

During my younger years, I worked for a year in New Zealand and whilst I was there I spent a few days tramping in the Nothofagus forests of Fiordland. Tramping trails in New Zealand aren’t quite like our well-worn public footpaths here in the UK. They are barely visible at all, marked only by the occasional orange triangle. As I walked through these woods, I experienced a quietness like I had never before. Not that the woods were quiet, the wind in the leaves and the chatter of birds kept me company as well as the sound of the forest floor crunching under my boots. It was an internal quietness. My mind, stripped of the pressures of everyday life, was calm.

I don’t think I can explain fully how spending an hour or two up in the broad spreading canopy of a Beech, walking a quiet woodland trail or sitting between the buttress roots of an ancient oak can give me a peace when my depression takes hold, other than that it is a place of safety in which to breath.

Numerous organisations and charities take advantage of this phenomenon, using woodland skills and workshops to assist vulnerable people. At Westonbirt our excellent community outreach programme has helped hundreds of people suffering with one form or another of mental health disorder.

As I write this I consider myself very lucky to be alive. And even luckier still that I get to spend my days in one of the most beautiful settings imaginable. I find that even in my darkest moments that I can be proud of myself for contributing to the upkeep of somewhere that provides so many with so much positivity. I enjoy the idea that on a daily basis I am benefitting from the work and visions of people who died long before their vision grew into fruition. Because I know that when I am no longer around, people will walk amongst the trees of Westonbirt Arboretum and enjoy what I too helped to create. But if I get the chance, as an old man, to return to Westonbirt and wander the glades to a tree I planted as a lad and lie on my back to watch the summer sun dance through the leaves, maybe I will think that without me, this tree would not be here, but without the tree maybe I wouldn’t be either.

Tree of the month: January 2017

January 6th, 2017

What is the tree of the month?

Cheng fir (Abies chengii)

Cheng Fir Tree Branch

Why is it tree of the month?

This species was described in the 1980s from our single specimen here at Westonbirt. It was collected as seed by the Scottish plant hunter George Forrest in the 1930s and has been grown in collections under various names since. Our historical records indicate that our plant was planted in 1938. Recent literature suggests that it may be a variety or form of the related Abies forrestii, though this is not a universally held view.

Where can I find it?

Our tree, the TROBI champion for height, grows close to Willesley Drive and Byhams Ride in Silk Wood. You can locate specimens using the Westonbirt map

Plant hunting…we’re back!

November 30th, 2016

After just over 3 weeks out in the field in Italy, we are now settling back into our daily routines here at Westonbirt.

The last portion of our trip was spent in the north east of the country, primarily to collect some of the European conifer species that grow in this area. We were working with staff from the Corpo Forestale dello Stato and as in the south, we benefitted from their encyclopedic knowledge of the native flora.

Collecting highlights here included Scots pine, Abies alba and Pinus mugo, all of which are currently important species here in the landscape at Westonbirt, though the vast majority of these are of no known origin. Our collections are significant as these plants will help inform us as to how Italian examples of these species will perform in our climate.

p1030441 p1000233

In total, we made 77 collections, 16 of which were also for the Millenium Seed Bank. Though we didn’t quite manage to collect everything on our target plant list (that’s nature for you!), strong connections were made with our Italian colleagues and we are well placed to explore further collecting options in the future.

For all of us, the experience was one that will remain with us forever. We were treated to incredible hospitality throughout and without our Italian colleagues; none of this would have been possible. To marvel at these plants in their native habitat is of course incredible and to collect seed that will become trees in the collection here at Westonbirt is truly special. We are looking forward to it!!

Dan, Dendrologist


Tree of the month : December 2016

November 30th, 2016

What is tree of the month?

Abies fraseri (Fraser fir)


Why is it tree of the month?

An increasingly common sight around this time of year, Fraser fir is widely used as a Christmas tree. It is however included on the IUCN Red List of Threatened Plants as Endangered, as it’s threatened by an invasive insect in its native range in the Eastern United States.

There it grows with a number of other species that also grow in the Westonbirt collection such as the American mountain ash, Sorbus americana and mountain maple, Acer spicatum.

In U.K cultivation it is generally considered not to be particularly long lived.

Where can I find it?

A small but fine specimen grows close to Holford Ride in Victory Glade and other, younger plants can be found elsewhere in the Old Arboretum. You can locate specimens using the Westonbirt map,


Plant hunting…week two!

November 3rd, 2016

We’ve just left Naples to head for Arrezo in the north.

From 21st to 25th October we collected in The Pollino National Park which straddles Calabria and Basilicata and covers 193,000 hectares with mountains up to a height of 2,266m and is dramatic.

Collections are now at 60 and one of the most notable is Pino loricato which in Italy only grows in Pollino.   A long hard 10K walk to the top but well worth it.


Seed collecting Seed collecting

We also went to Alessandria del Caretto on the eastern side of the park where six species of maple grow including Lobel’s maple, Norway maple and Montpellier maple but very little seed collected.

It’s fantastic, but the less glamorous side is spending hours in launderettes , DHL offices, and travelling!

Tree of the month: November 2016

October 27th, 2016

What is tree of the month?

Pinus nigra  (Black pine)


Why is it tree of the month?

An important tree in the Westonbirt landscape, black pine is native to parts of Europe and is split into 5 subspecies, though it’s taxonomic treatment is somewhat controversial! We hope to add to our current specimens through collections we have made in south Italy.


Known as Calabrian pine to the locals, huge trees of what is generally known as Pinus nigra subsp. laricio grow in Aspromonte National Park and elsewhere.

Where can I find it?

Young and mature specimens can be found throughout the collection. You can locate specimens using the Westonbirt map,
