Grey Alder is an ideal small tree or bush for cold and wet situations. This very hardy tree has grey undersides to its leaves with yellowish brown catkins which are borne in late winter. The leaves are pointed at the end which makes it easier to distinguish between this and A. glutinosa. It has root nodules, as with other Alders, that fix nitrogen from the air and therefore helps with soil fertility – good for sites that need pioneers.
