Populus trichocarpa

Populus trichocarpa, commonly known as black cottonwood, is a deciduous tree native to the western United States and Canada, including regions such as Alaska, Alberta, British Columbia, California, Idaho, Montana, Nevada, Oregon, Utah, Washington, and parts of Mexico Northwest. This tree thrives in moist environments such as riverbanks and wetlands, growing up to 40 meters tall. Known for its light requirement of full sun and adaptability to various soil types—ranging from sandy to clay—it can be found across a wide range of habitats. The black cottonwood is notable for its ornamental value and its edible qualities, as both the flowers and inner bark are consumable. The inner bark can be harvested and prepared by peeling it from the tree, then dried or eaten raw. Flowers can be collected and used fresh in salads or dried for later use. Both parts add a mild, slightly sweet flavor to dishes. In traditional medicine, Populus species have been used to support immune health, often prepared as a decoction from inner bark or sap. The distinctive feature of this tree includes the presence of long, soft hairs on the underside of young leaves, giving it a silvery appearance. Cultivation of black cottonwood requires a planting site with good drainage but consistently moist soil. It is hardy in zones 4-8 and can be propagated through cuttings from the inner bark or flowers. This versatile tree also has multiple practical uses, including adhesive, weaving material, containers, cork, dye, fire starter, textiles, paint, rooting hormone, scourer, soap, soap making, and waterproofing.
