From Hibiscus in Shoreditch, Golden Rain Trees in Osterley, and Bottlebrush trees in Pimlico, London has unexpected and fascinating street trees. Our urban forest, often under appreciated, is extremely varied and, what grows where differs around the city. So, which are the most interesting boroughs for a discerning London street tree admirer to visit, and why? Read on to find out about 5 London boroughs that, in no particular order, stand out…
Until about 20 years ago, Hackney was one of the less forested boroughs but around the turn of the millennium, it started catching up, and boy, did it catch up. Hackney now is a veritable arboretum: you can find streets lined with Kentucky Coffee Trees (Gymnocladus dioicus) in Clapton, Hibiscus (Hibiscus spp.) in Shoreditch, Wild Service Trees (Sorbus torminalis) in Stoke Newington and Scots Pines (Pinus sylvestris) in Dalston. The urban forest is relatively young here but what it lacks in maturity, it makes up for in diversity. There is something of interest at virtually every turn, and it will be exciting to see this part of town mature in the coming years.
Southwark is a big borough (by inner London standards), stretching from the southbank at London Bridge all the way east to Canada Water and south to Dulwich and Nunhead. Street tree planting is varied, and, like Hackney, you don’t have to go far to find something of interest. There’s a street of spectacular Yoshino cherries (Prunus x yedoensis) in Herne Hill, some of the biggest Tree of Heaven (Ailanthus altissima) specimens in London can be seen in Bermondsey and Magnolias (Magnolia spp.) are planted outside Borough Church. Southwark has pioneered some unlikely species too, including Persian Silk Trees (Albizia julibrissin) and, one of my favourites, the Strawberry tree (Arbutus unedo).
That long ribbon of a borough, Hounslow, has been planting great trees for years. It’s got everything, from stately Planes (Platanus x hispanica), classic Lime tree (Tilia x europaea) boulevards and landmark Cherry (Prunus spp.) avenues to being perhaps the best place to see mature Golden Rain Trees (Koelreuteria paniculata) in London. Of these elder statesmen, a tree right outside Osterley Tube station is an arboreal landmark, displaying beautiful coral pink new leaves in spring, yellow flowers in high summer, glorious autumn foliage and seed lanterns in the winter. There’s at least one tree in this borough playing host to Mistletoe too.
My home borough, so I might be a little biased, Islington is the part of town I know best. It’s the best borough for Caucasian Wingnuts (Pterocarya fraxinifolia), a fabulous spreading tree easily identified by tell-tale dangling clusters of little winged nuts, and is home to some other intriguing species. Islington was, of course, the first borough to plant Olive trees (Olea europaea) on the street – to reflect its Greek and Turkish communities perhaps? It is also home to some great Elm trees of various types including the Chinese Lacebark Elm (Ulmus parvifolia), the largest tree of this species in the country can be seen planted outside the Whittington Hospital. But perhaps what Islington is most noted for is ornamental fruit trees; dotted about the borough, the street tree aficionado can find rare pears (Pyrus spp.), notable Crab apples including plenty of Chonosukis (Malus tschonoskii), and unusual Yunnan Apples (M. yunnanensis). There’s also a good stock of flowering cherries including examples of the now rather out of fashion Bird Cherry (Prunus padus).
Westminster plays host to the ‘Government Estate’, so has the job of keeping some of the most visited, filmed and photographed parts of the city looking green and pleasant. There are a lot of mature Plane trees in Westminster, as you might expect, adding to the grandeur of Whitehall and parts of the West End. But scratch the surface and you will find more interest around many corners. Westminster has pioneered the planting of Gingkos (Gingko biloba), a species well adapted to life in the busiest parts of town, and even in this most urban borough, English Oaks (Quercus robur) can be found outside Charing Cross and Pimlico stations. Perhaps the finest Mimosa (Acacia dealbata) to be found on the frontline can be seen in Pimlico and there’s even a street lined with Australian Bottlebrush trees (Callistemon citrinus)!
These trees and many more feature in my newly published book, London’s Street Trees and I shall be talking about the urban forest at Stanfords Map and Travel Bookshop in Covent Garden on June 5th. Please do join me!
