Discover the Andes Alder, also known as Alnus acuminata, a remarkable tree species found across South and Central America. This deciduous tree from the Betulaceae family can grow up to 80 ft tall with a straight trunk up to 60in thick. Its bark has many yellowish lenticels while the leaves are simple, oval with toothed margins. Its inflorescences are catkins, having separate male and female flowers on the same tree. Once the flowers develop into 2cm (0.8in) long dehiscent woody fruits, they release 80 to 100 winged seeds per fruit. This fast-growing tree is a pioneer species used for watershed protection and can be used for soil improvement as it has root nodules that fix nitrogen. It prefers silt or sandy silt soils and is tolerant of poor soils and acid conditions. Its timber is light to mid reddish-brown and fine-grained, and is used for building bridges, pilings, making coffins, boxes, crates, furniture, and plywood. It also makes excellent firewood that burns steadily. Explore Alnus acuminata, a versatile tree species in your backyard.
