These are alders - excellent trees or shrubs, almost all deciduous, for growing in damp places, typically along the banks of rivers. They are related to the birches, Betula, and originate from the temperature regions of the northern hemisphere. They have long male catkins and shorter female catkins, both kinds on the same plant. The female ones remain after flowering, becoming woody and brown, and open when they are ripe to release the small seeds.

Alnus viridis subsp. viridis is a large shrub or small tree with smooth grey bark and ovoid, shiny green leaves. Unlike in other alders, the catkins appear late in spring, after the leaves emerge. The species occurs in Europe, Asia and America, but this subspecies is only found in central Europe.

Alnus - some other suggestions
invisible.gif Alnus fauriei is a large shrub, usually multi-stemmed, for damp places, only recently introduced to cultivation, and uncommon in its native Japan. It has very large, rounded leaves and long, purple catkins.
invisible.gif Alnus glutinosa 'Laciniata' is the cut-leaved alder, an interesting variant on the usual form, differing in having deeply divided leaves. It grows best by water, where it will produce some suckers if it is happy, but will perform well elsewhere.
alnus_sieboldiana.jpg Alnus sieboldiana is very attractive, with broad, roughly ribbed, serrated leaves. It has haging, yellow catkins, and these are followed by quite large ovoid cones, greenish yellow at first but later becoming brown.
