* Alder trees also have a heavy leaf canopy and when the leaves fall in the autumn they help to build up the humus content of the soil. * This is an excellent pioneer species for re-establishing woodlands on disused farmland, difficult sites etc.

* Native to most of Europe, including all of the British Isles and Fennoscandia and locally in Southwest Asia. * Tolerant of clipping and maritime exposure, the alder can be grown in a windbreak or a hedge.

Northeastern North America, Greenland. * Bright green leaves. * It is a large shrub or small tree 3-12 m tall with smooth grey bark even in old age. * Alnus viridis subsp. * It is sometimes used for afforestation on infertile soils which it enriches by...

* A decidious Tree growing to 22 m (72ft 2in) at a fast rate. * Native to temperate forests, stream-banks, swamps and roadsides in northeastern Asia and Japan.

* Bacteria on the roots fix atmospheric nitrogen - whilst this enables the tree to grow well in quite poor soils it also makes some of this nitrogen available to other plants growing nearby.

Bring the outdoors in with these natural alder cones. Lower Ph provide a food source for the shrimp by creating favorable conditions for micro growth and all shrimp seem to be attracted by them doesn't matter the species.

In addition, bacteria on the roots fix atmospheric nitrogen - whilst this enables the tree to grow well in quite poor soils it also makes some of this nitrogen available to other plants growing nearby.

Fruit is small black berries that drop in late summer to early fall. * The wood is used to make wooden nails, shoe lasts, veneer etc. Individual plants can produce as many as 400-1800 fruits with three seeds each.

* Plants can be grown as an informal (untrimmed) hedge, though they are also amenable to trimming. * This variety is upright growing, very columnar. * The cultivar 'Tallhedge' has been selected for hedging.
