Features and care
Alnus glutinosa, known as the common alder, is a deciduous tree linked to wet landscapes. Its fast growth, dense foliage and persistent small fruiting cones make it of interest for planting around ponds, rain gardens and riverside-style compositions.
It forms an initially pyramidal crown, sometimes on multiple trunks, with rounded to obovate, green, glossy leaves. Male flowers hang in catkins at the start of spring, while female flowers give rise to small cone-like structures. These ripen in autumn and remain visible through part of winter.
It establishes in sun or part shade and can reach 15 to 25 m. It needs moist to waterlogged soil and a very high watering regime that keeps continuous moisture around the roots. It tolerates humid environments and frost from cold climates very well, with USDA hardiness 3-7. Keeping water available is a priority during establishment.
At Ornacom we cultivate each specimen directly, guaranteeing a balanced size and abundant flowering from the first years of planting.
