Alnus glutinosa, commonly known as the black alder, is a deciduous tree native to Europe, including the British Isles. It is a versatile and resilient species, often found thriving in wetland areas, riverbanks, and marshes, where its roots can help stabilise the soil and prevent erosion.

The black alder typically grows to a height of 20-30 metres, with a broad, conical crown that becomes more rounded with age. Its bark is dark brown and fissured, often developing a distinctive, almost black hue as the tree matures. One of its most notable features is its leaves, which are rounded with a slightly serrated edge and a glossy, dark green surface that turns yellow in the autumn.

In early spring, Alnus glutinosa produces catkins – the male catkins are long and yellowish, while the female ones are shorter and reddish. These mature into woody, cone-like fruits that persist on the tree throughout the winter, providing a valuable food source for wildlife. The black alder also forms symbiotic relationships with nitrogen-fixing bacteria in its root nodules, enriching the soil and benefiting neighbouring plants.

Due to its adaptability and ecological benefits, Alnus glutinosa is often used in reforestation and habitat restoration projects. It supports a wide range of wildlife, including insects, birds, and aquatic species, making it a vital component of the British natural landscape.

About Us

During this time, we have developed a large stock of trees, mature evergreen shrubs, conifers, Japanese maples, cedars and olives. What sets us apart from a generic garden center is solid unwavering focus on trees and some bigger shrubs. You will find thousands of trees, hundreds of varieties and lots of experts who are working on the nursery and more than willing to help you to choose a plant for you.
