Alnus tenuifolia

Alnus tenuifolia, commonly known as narrow-leaved alder, is a deciduous tree or shrub native to the western and northwestern United States, including Alaska, Alberta, Arizona, British Columbia, California, Colorado, Idaho, Montana, Nevada, New Mexico, Northwest Territories, Oregon, Saskatchewan, Utah, Washington, Wyoming, and Yukon. This plant thrives in moist, wet conditions with medium to heavy clay soil, preferring a pH range of 5 to 7. It is known for its edible flowers, which can be consumed raw or used to make a light tea, adding a mild flavor to dishes and providing nutritional value. Narrow-leaved alder grows up to 9 meters tall and has distinctive narrow leaves that set it apart from other alder species. Its growth form is thicket-forming, making it an interesting addition to gardens or natural landscapes. This plant can be found in habitats where it receives full or partial sun and serves as a pioneer species, contributing to erosion control and acting as a nitrogen fixer. It also has utility in lumber production and tannin extraction. Alnus tenuifolia is hardy in zones 5-7 and grows rapidly, making it an excellent choice for areas where quick establishment of vegetation is desired. Its ability to thrive in moist conditions and its fast growth rate make it suitable for use in reforestation projects or as part of a landscape design aimed at improving soil health and preventing erosion. While not medicinal, this plant offers practical benefits through its edible flowers and ecological contributions.
