The Red Alder (Alnus rubra) is a vigorous, fast-growing deciduous tree native to the Pacific Coast, perfect for homeowners looking to establish a quick canopy or manage wet soil conditions. Recognized by its elegant, smooth light-gray bark and broad, oval leaves with distinct serrated edges, this tree offers a clean, lush aesthetic. One of its most unique ecological benefits is its ability to fix nitrogen in the soil, naturally improving the health of surrounding plants and making it an excellent choice for land restoration or areas with poor soil quality.

While it thrives in moist-to-wet environments—making it ideal for stream banks, pond edges, or low-lying spots—it also serves as a stately shade tree in larger landscapes. In the early spring, dangling catkins add subtle texture before the deep green summer foliage takes over. If you need a hardy, rapid-growth solution for a damp site, the Red Alder is a reliable and ecologically sound investment for your property.
