The green alder is a shrub branching from the base and attaining a height of 1- 3 in. The male catkins are already visible in autumn. The twigs are flattened, brownish-green with whitish warts.
The buds, unlike those of other alders, are stalkless, pointed, and coloured greenish brown. The catkins appear together with the leaves in April to May. The cone-like fruit is only 1 cm long and is a paler colour and less woody than that of the common alder. The small-winged fruits are yellow-brown and resemble those of the birch.
It is a high-mountain shrub growing mainly in the Alps and Carpathians, where it forms dense thickets above the tree line at elevations of 1300 to 2200 m; it does not occur in Britain. The Urals and western and central Siberia are the home of a closely related geographical variety. The green alder stands up to abundant shade better than dwarf pine and is found mostly on north-facing, damper slopes. It is of importance in soil retention and prevents the formation of snow and rock avalanches.
Alongside streams and gullies it occasionally descends to lower levels, where it covers uncultivated areas. It suckers freely when cut and also puts out root suckers, by which it is easily propagated.
The hazel is a shrub with straight shoots 3-6 m high, the bark smooth and brownish. The alternate buds are round ovate and covered with several scales. The, male catkins are visible already in autumn, growing in length and maturing in March when their yellow pollen falls on the female, bud-shaped flowers with several slender carmine-red stigmas. By autumn the female flowers develop into a woody oval nut 1-1.5 cm long, enclosed in a green leafy cup. The kernel is oily and very tasty. Propagate by nuts sown in autumn. if stored dry and sown in spring germi- nation is delayed until the second spring.
It grows in western, central and southern Europe and is mostly parasitic on fir and pine trees, and of the deciduous species on poplars, birches, maples, limes and fruit trees. Parasitic on oaks is the closely related yellow-berried mistletoe (Loranthus europaeus), which is deciduous; this species does not occur in Britain, where mistletoe is occasionally found on oaks.
