Alnus glutinosa (Common Alder) - Bareroot - Bundles of 10

Alnus glutinosa, commonly known as the black alder or European alder, is a medium-sized deciduous tree native to Europe, parts of Asia, and North Africa. It thrives in damp environments such as riverbanks, wetlands, and floodplains, often forming dense stands in these habitats. The tree is easily recognized by its rounded, serrated leaves that remain green until they fall in late autumn, and by its dark, fissured bark. It produces small, woody cone-like structures that contain seeds and distinctive catkins that appear in spring. Black alder is notable for its ability to fix nitrogen in the soil through a symbiotic relationship with Frankia bacteria in its root nodules, making it valuable for soil restoration and improvement. This hardy tree plays a crucial role in stabilizing riverbanks and supporting wildlife, providing habitat and food for various species of birds and insects. Its wood, resistant to water, has historically been used in construction, especially for submerged structures like piers and canal linings.   Please see our GUIDE TO PLANTING HEDGES for more info.
