Red Alder Tree Seeds (Alnus rubra) 50+Seeds
Red Alder Tree-It is the largest species of alder in North America and one of the largest in the world, reaching heights of 20–35 m. The official tallest red alder (1979) stands 32 meters tall in Clatsop County, Oregon ( USA ). The name derives from the bright rusty red color that develops in bruised or scraped bark. The bark is mottled, ashy-gray and smooth, often draped with moss . The leaves are ovate, 7–15 cm long, with bluntly serrated edges and a distinct point at the end; the leaf margin is revolute, the very edge being curled under, a diagnostic character which distinguishes it from all other alders. The leaves turn yellow in the autumn before falling. The male flowers are dangling reddish catkins 10–15 cm long in early spring, and female flowers are erect catkins which develop into small, woody, superficially cone -like oval dry fruit 2–3 cm long. The seeds develop between the woody bracts of the 'cones' and are shed in the autumn and winter.
Red alder was widely employed medicinally by native North American Indians who mainly used the bark to treat a wide range of complaints. The plant is little used in modern herbalism. The bark is appetizer, astringent, cathartic, cytostatic, emetic, stomachic and tonic. The bark contains salicin, which probably decomposes into salicylic acid (closely related to aspirin) in the human body. This is used as an anodyne and febrifuge. An infusion of the bark has been used in the treatment of many complaints such as headaches, rheumatic pains, internal injuries and diarrhoea.
