Common Alder

The bark of Alnus glutinosa, commonly known as the Common Alder, is has its smooth, greyish-green to dark brown surface. As the tree matures, the bark develops shallow fissures and becomes somewhat corky in texture.
In terms of height, the Common Alder typically grows to be a medium-sized tree, reaching heights of 60 to 80 feet (18 to 24 meters) at maturity.

The Appearance

A medium-sized deciduous tree with a conical shape, dark green leaves, and distinctive woody cones. It can grow up to 70 feet tall.


The Produce

The common alder produces cone-like structures as its fruiting bodies. These structures are called strobiles or catkins.


The Flowers

Produces small, yellow catkins in early spring, which are followed by woody, cone-like fruits.


The Leaves

They are broadly oval to elliptical in shape, with serrated margins.


The Bark

The bark is dark brown and becomes fissured with age.


The Habitat

Prefers moist, well-drained soils and full sun. Commonly found along riverbanks and wetlands.


The Ecology

Provides habitat and food for various wildlife, including birds and insects. The roots improve soil fertility by fixing nitrogen.


The Culture

Used in traditional medicine and for timber, particularly in waterlogged conditions as the wood resists decay.


Fun Facts

The Common Alder improves soil fertility through its symbiotic relationship with nitrogen-fixing bacteria in its roots.
