Japanese Pagoda Trees (Styphnolobium japonicum) outside Archway Station
Dear Readers, we are surrounded by street trees but they go largely unnoticed, flowering and fruiting and developing autumn foliage without so much as a glance from us as we hurry past. Yet our built environment would be so much poorer without their shade and freshness, and so would our wildlife. I was very excited to find that, in Paul Wood’s new book ‘London’s Street Trees: A Field Guide to the Urban Forest‘, there are a number of walks to follow. One of them is in Archway, just a mile or so down the road from East Finchley. And so, on a day of volatile weather, I took myself down the hill to explore this familiar place with a new focus.
The area outside the station is newly pedestrianised, and there are a variety of young trees, including some Japanese Pagoda trees. Wood points out that these are easily identified by the green bark on the new growth.
Note the green bark on some of the twigs
This tree is a member of the pea family, and, when it’s all grown up, it may have racemes of white flowers. I say ‘may’ because you can wait 30 years for a tree to flower. In the meantime, it has soft, feathery foliage and an elegant, graceful habit. The tree is Chinese rather than Japanese, and in Chinese legend it is believed to attract demons. Let’s hope that this isn’t the case, as the area around the station attracts many lost souls as it is.

In fact, the space around Archway has been somewhat ‘tarted up’ over the past year. All the bus stops have moved, a source of considerable irritation to folk like me who haven’t worked out where the 143 goes from. Also, a cycle lane runs right across the middle of the pedestrianised area, so we will see how that works out.

Following the route in the book, I head along Junction Road. Here, I see a splendid example of all the things that street trees have to put up with.
A pit a metre deep has been dug around this tree, and this is currently full of bits of yellow plastic drain pipe, drinks cartons and cigarette ends. No one was working there when I visited, so I will be interested to see how long the poor tree remains with some of its roots exposed. Plus, there is a lot of traffic here, so the plant also has to contend with a lot of pollution. No wonder London Planes are the trees of choice for so many of London’s big roads, what with their resilience and the way that they regularly shed their bark, along with any unpleasant chemicals.
I turn left onto St John’s Grove and there, towards the junction with Pemberton Road, I see two Dawn Redwoods (Metasequioa glyptostroboides).
I must have walked past these trees on my way to the Cat Protection shelter on Junction Road hundreds of times when I was a fosterer, and yet not noticed them. Dawn Redwoods come from a single Chinese forest, where there are less than 5000 individual trees left, and they were only discovered by scientists back in 1946. In its native Lichuan the plant is known as the Water Fir. It is related to the Giant Redwoods, and though not quite as much of a goliath as these trees it can still grow to 200 feet. It is unusual in being deciduous, and has a light, delicate appearance. It came as a surprise to me to see a tree that is classified as Endangered in the wild is doing well just off the Holloway Road, but then life is full of surprises.

Looking back down Pemberton Road, I see that the council tree surgeons have been hard at work.
The pollarded plane trees always look to me as if they are raising their fists to the sky in fury. They appear to be almost indestructible, however.
Pollarded tree coming into leaf
Paul Wood explains that the main reason that trees are pollarded is prevent the tree from becoming too large. A big tree is a thirsty tree, and it may drink up all the water in the soil. This is known to lead to subsidence, a particular problem, I imagine, in the hilly environs of Islington. If the trees are pollarded every three years, then a court will most likely throw out any claims by a householder, on the basis that the tree always takes the same amount of water. At any rate, although the pollarding looks ugly, it seems to only encourage the trees (at least if the behaviour of my whitebeam following its pruning eighteen months ago is anything to go by – every time it’s cut back, it grows through more vigorously).
Onwards! I cross Holloway Road, and head along St John’s Villas, the scene of much tree-related drama a few years ago.
Sand Pear trees (Pyrus pyrifolia)
There are seven Sand Pear trees in this street, an unusual choice of fruit tree, as they produce particularly large and abundant fruit. In 2007 there was a particularly splendid crop of fruit. As no one knew what to do with it, the pears splattered onto residents’ cars and turned the pavement into a slippery mess. This highlights one of the problems of fruit-bearing street trees – if no one harvests the fruit, the result can be piles of fermenting crab apples or rotting plums. On my street, a neighbour spends much of the time in autumn sweeping up slushy crab apples. At any rate, in St John’s Villa some residents wanted the trees cut down, while others were ready to link arms to protect them. In the end, the council agreed to harvest the pears, and some of the residents took to making perry, a kind of pear cider. A win/win solution for everyone, I’d have thought! When I visited the road was quiet, except for the chirping of baby blue tits from one of the nest boxes, so it seems that the Pear Wars have come to an end, at least for now. For more on this story, have a look at Paul’s blog here.
As I walked along Prospero Road, I was literally led by the nose to the most beautiful show of jasmine and climbing hydrangea I’ve seen in a long time. It perfumed the air for tens of metres in every direction. I only wish that this blog were scratch and sniff, I’d love to share it with you.
On the corner of Lysander Grove, Wood points me to another unusual tree, the Chinese Lacebark Elm (Ulmus parvifolia). Remember the name, because we will meet another of these trees next week.
This elm is largely resistant to Dutch Elm Disease ( I posted about the English Elm here ) and has a kind of splendid grace and poise. It seems to be very popular for Bonsai, but I rather like it as a ‘proper’ tree, bringing a touch of elegance to a North London Street corner.
During a mistaken detour along Lysander Grove, I spot an over-enthusiastic Clematis montana, sharing its beauty with everyone. I wonder where it will end up? Crouch End at this rate.
Once back on the correct path, I see the most splendid green roof on top of a garage, full of red campion and ox-eye daisies. Well done, that home owner! It goes to show that even a small space can provide some beauty and interest.

Up past the Village Garage on Cressida Road (yes, there’s a Shakespearean theme in these parts), and there are two Photinia ‘Red Robin’ trees. What a shame that I’ve missed the height of their flowering. I must pop back when they’re in their autumn colour. Photinia are much more often grown as shrubs, but these two are very striking in their tree form. The plant is a member of the rose family and is related to the apple: the fruit is said to be popular with birds such as thrushes and waxwings, a good example of how valuable street trees can be for wildlife.

And now, as I hit the halfway point of my walk, I look back towards the towers of Canary Wharf, with the pyramid of One Canada Square reflecting the fleeting sunshine. I had no idea of the sheer variety of the street trees here, and the walk has thrown up a number of surprises. As I head towards what Wood describes as ‘one of the street tree hotspots of London’, Dresden Road, I wonder what else I will find.
London friends, if you want to know what the street trees are in your area, have a look at this map. It’s not perfect, but put in your postcode and see what’s on your streets….
