Common Alder Hedging
Alnus glutinosa
- A vigorous deciduous hedge that forms a dense leafy screen to provide the perfect habitat for birds, small mammals and insects
- Fresh green rounded foliage with long catkins emerging from purple buds in summer and small woody cones in autumn
- As well as supporting over 90 wildlife species, this hedge is one of the most adaptable. It can live in wet and poor quality soils, making it ideal for coastal positions, river banks and other waterlogged positions
- A fully hardy, fast growing shrub which will reach a height of up to 5m but can easily be maintained at 2-5m
- Can be used as a windbreak and to shelter other plants from harsh weather conditions

Meet Cameron
Putting shrubs in the starlight (and boy do they shine…)
Cameron is mad about plants, which is lucky, really, because he’s absolutely surrounded by them here at the nursery. Having studied at the Student Plant Unit at Pershore College, Cameron went on to compete at the Grand Finals for the 2022 Horticulturist of the Year Awards. With a team of dedicated growers on hand to help, Cameron utilises our industry-leading nursery (and the lovely, fertile conditions of the Cotswolds) to grow shrubs that aren’t just good-looking, they’re good-growing too.
