With the exception of a few species, such as Alnus nitida and A. maritima, which flower in September and October, all the Alders develop their blossoms in February and March. The common Alder (A. glutinosa) and its varieties are perhaps as ornamental as any at that time. Like the Willows, they look best and grow best in association with water. In such a position an Alder at that time, leafless, but laden with its slender, greenish-yellow catkins, is a beautiful object, and characteristic, too, of our English landscape. Other species possessing a similar quiet beauty are Alnus incana, A. viridis, A. oregona, and especially A. cordifolia with its green and yellow catkins.
