Alnus, commonly known as Alder, is a genus of trees valued for their rapid growth, resilience, and ecological benefits. They are frequently found near water bodies, playing a crucial role in riparian ecosystems.
Their extensive root systems stabilise banks, preventing erosion, while their symbiotic relationship with nitrogen-fixing bacteria improves soil fertility. Beyond their functional significance, Alders possess notable aesthetic qualities. Varieties like 'Alnus glutinosa' and 'Alnus incana' display distinctive catkins and attractive, serrated leaves, contributing to their visual appeal.
Whether utilised for enhancing wetlands, stabilising riparian zones, or simply adding to the diversity of a landscape, Alnus trees offer a valuable combination of practicality and visual appeal. Their presence benefits both the environment and the aesthetics of a space.
