European Alder
Black alder is a medium-sized, fast-growing, deciduous tree native to Europe, western Asia, and northern Africa, but has naturalized in other regions including the northeastern and central United States. It bears handsome, glossy, dark-green leaves from spring to fall, and its catkins provide mild interest in winter and early spring.
Requiring sun but thriving in most soils, it excels as a shade or screening tree in sites that are too damp or barren for other trees. It may be invasive in some situations.
