When I was at horticultural college, one of my tutors was a keen beersman. His arboriculture lectures would include examples of the trees we were studying, pointing out their proximity to a hostelry. Along the road from The Merchants Arms are some fine examples of Betula utilis var. jacquemontii, outside The Highbury Vaults a splendid Davidia involucrata and so on. This weekend I returned to the city that I had once called home and, with an old friend, walked the streets following a set route which highlighted little known points of interest. It is strange how you don’t really “see” a place until you return and what I “saw”, amongst other things, was an amazing variety of street trees. Not young trees planted recently in a flurry of urban regeneration, but trees that had been insitu for decades. Blue cedars, ancient oaks, golden ginkos, and pendulous birches. This Catalpa bignonoides, the Indian Bean Tree, replete with beans, caught my eye just before we headed off to the location of a 17th century massacre and a framed Banksy. This was swiftly followed by a trip to one of the aforementioned hostelries, an education is indeed a wonderful thing.
