Alder grey

              The grey alder outside St Giles', Cripplegate, was felled in 2010, but it is very difficult to completely destroy a tree, and it is re-emerging as a coppice. Coppicing completely changes the look of a tree, and initially it becomes bush like. However, if left for many many years each shoot can grow into a tree in its own right. This is unlikely to be allowed to happen here, though.

              Like the common alder, the grey alder needs to have damp soil to grow, and for this reason it is usually found beside ponds, streams or rivers. It follows from this that there are not many examples in central London. The Italian alder is much more common because it can survive away from water. The Italian alder shares many features with the grey alder: cones, catkins and a similarly shaped leaf.


St Giles' church.is beside a pond,
which suits the grey alder.
