The alder buckthorn is a sparsely branched shrub or tree 3-7 m in height. When young the bark is violet-brown with whitish corky pores (lenticels); the buds have no ,scales but are covered with rust-felted hairs. The flowers appear successively between May and August, the fruits likewise ripening successively between July and September, turning from green to red and black. It is a fast- growing shrub attaining an age of 80 years or so.
Widespread throughout most of Europe, its range extends far to the north and eastward to Siberia. In central and western Europe it grows in abundance in damp and swampy sites in riverine woods and up to mountain elevations. It also occurs in acid oak stands and pine woods where the level of underground water is near the surface.
Because of its dense root system and tendency to develop root suckers it is also sometimes planted on hillsides to prevent erosion. In some parts of Europe experiments are being carried out to cultivate it in plantations for tannin, as its leaves contain up to 25 per cent of this substance.
Tamarisk is a thin shrub or small tree, 2-7 m high. The shoots are slender and green to reddish brown. The short terminal twigs are shed together with the leaves. The buds arc small, the leaf buds slightly pointed, the flower buds round. The pink flowers are borne from June till the end of July. The capsules ripen and split in September. The seed retains its powers of germination for only a few weeks and must be sown in moist soil.
This species is widespread in southern Europe, its range extending from Spain and France as far as Asia Minor. It is naturalized near the coasts of southern England. Where native, it grows in the coastal belt, mostly in river valleys and on river terraces, and prefers light soils, also tolerating salty soils. In central and western Europe it is cultivated as an ornamental shrub in parks and gardens.
This shrub is widespread throughout most of Europe, its range extending northward to the 60th parallel and eastward to Siberia. It grows mostly on dry, sunny banks and rocky sites in hilly country. A light-loving, frost-resistant shrub, it does well even on poorer soils. The wood is hard, with brownish-reel heartwood and yellow- white sapwood. The bark and fruits were used to make natural dyes and for medicinal purposes.

In garden planning, making the formwork carefully is vital to the success of the wall, but it is far more taxing than the actual laying of the concrete garden wall.
