Rough alder (Alnus rugosa) is a large native shrub with a bushy habit, known for its rapid growth and its ability to stabilize soils. Ideal for watercourses or in moist soils, it is perfect for ecological restoration of banks or wild gardens. Its dense foliage and spring catkins bring a rustic and natural touch, while providing a valuable habitat for local wildlife. Its early flowering, following the melting of the snow, attracts a wide variety of insects and birds, thus contributing to biodiversity.
