Red Alder
Alnus Rubra
Overview
Red Alder (Alnus rubra) is a deciduous tree native to the Pacific Northwest. It thrives in moist environments, quickly reaching 50-80 feet high with a 20-30 feet canopy spread. Noted for its smooth gray bark and serrated leaves, it features catkins and small cones. Alder enriches soil by fixing nitrogen, making it beneficial for companion plants. Ideal for creating natural screens or riparian buffers in landscape designs.
