Botanical Name:Alnus glutinosa
Common Name:European alder, common alder, black alder
Family Name:Betulaceae - birch family
General Description:Alnus glutinosa is an intermediate size tree that can be grown single stem or clump. It has been a popular plant in the landscape due to its size, shape, winter texture and ability to grow in diverse landscape settings. European black alder is especially useful for wet sites and poor infertile sites as it has the ability to fix nitrogen in nodules on its root system. However, it is a non-native tree that has escaped cultivation and can now be found along rivers and other natural habitats in the Chicago area. According to The Morton Arboretum, this plant is invasive and should not be planted.
