Alnus Incana (Gray Alder)-This fast growing, conical shaped tree makes a good substitute to common alder, liking cold, wet environments and ideal for colonising uncultivated land. The grey alder is distinguishable from the common alder by its pointed leaves, which are a dark green with a grey underside. The grey alder grows to be a medium sized tree, and is very light demanding.
Fruit: Green cone like structures that turn brown in the autumn before shedding seeds.
Timber: The timber is soft and of low density.
Soil Types/Habitat: Will tolerate most soil types. It is better than the common alder at coping with dry chalky soils.
