Alder grey

              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.
