At the moment, the Woodland Trust is doing a thing inviting people to name their tree of the year. More of that over here – https://www.woodlandtrust.org.uk/visiting-woods/tree-of-the-year/
I’ve been giving this a lot of thought. Perhaps quite naturally, people tend to pick large, ancient, dramatic trees. I do have a couple of pretty large oaks in viable walking distance, but they’re in amongst other trees so impossible to photograph. There’s another oak on the canal that I like not least because it so often has a heron stood in it. Most of my favourite trees aren’t that dramatic.
I love the wild plum on the cycle path, with its cheery flowers in early spring and tart summer fruit. There’s a copper beech I really like on one of my routes, and a number of urban trees in town whose shade I welcome on hot days and who provide homes for creatures. Around my home there are ash trees – young and pushy, and none of them standout but it’s because of them that there are so many wild birds outside my windows.
I think the short of it is that there are many trees I like and none at the moment that have become special to me in a way that makes me want to say ‘this one tree here should be tree of the year’. But it may be that you do have a particular tree in mind and can jump in and tell everyone about it.
