Alnus rubra

Alnus rubra, commonly known as Pacific or California alder, is a deciduous tree native to the Pacific Northwest and northern California, including regions such as Alaska, British Columbia, California, Idaho, Montana, Oregon, Washington, and Yukon. This member of the birch family (Betulaceae) thrives in moist environments like riverbanks and swamps, growing up to 20 meters tall with a width of 17 meters. It is adaptable to light conditions ranging from full sun to partial shade and prefers medium to heavy clay soils. Pacific alder has both ornamental and practical uses. Its fast growth rate makes it suitable for hedgerows, windbreaks, erosion control, and as a nitrogen fixer in the soil. The inner bark and flowers are edible; indigenous peoples consume these parts fresh or dried. However, the sap is not commonly eaten. This tree also serves as an important resource for fire starters and can be used to produce dye. While Pacific alder is hardy in zones 7-8, it generally performs well in temperate regions. For cultivation, ensure consistent moisture; avoid drought stress. Propagation can occur through seeds or cuttings. Pacific alder plays a significant role in its ecosystem while offering culinary benefits and practical applications for various uses.
