European Alder

Alnus glutinosa

Also called Black Alder, this tree is tall and narrow, often with multiple trunks that develop shallow vertical cracks as the tree ages. A sticky resin coating the leaves, twigs and buds provides the species name, “glutinosa.” Its cone-like catkins slowly release seeds through winter, making them a valuable food source for wildlife.
