Holly Shrub

By Jada Aaron

Holly is an evergreen shrub or tree 2-10 m in height with a conical crown. The bark is smooth and grey-brown. In older trees the leaves in the upper part of the crown arc only slightly spiny. The flowers, borne in the axils of the leaves, appear in May-,June. The red fruits ripen in October and remain on the tree until late in the winter. In Great Britain and the United States it is used as a Christmas decoration.

A native of western and southern Europe, it thrives exceptionally well in the moist and mild coastal climate. It requires partial shade and often grows in woodland. In the Alps it is found at elevations up to 1200 m. In central Europe it is often planted in parks, though it suffers great damage by frost in severe winters.

The spindle tree is an upright shrub or small tree, 2-6 m in height. The shoots are green, tinted red on the side exposed to the sun, markedly four- angled. The buds are ovate, green, often sub- opposite. The leaf scars are whitish.

The smoke bush is a shrub or tree glowing to a height of 2-8 m and forming a broad, rounded crown. The shoots are violet-brown, the buds small with pointed tips, borne in terminal clusters. The twigs when broken and leaves when crushed have a strong aromatic scent. The flowers, often dioecious, are borne in feathery panicles in June. The fruits ripen at the beginning of September. Both the flowering panicles and fruits make the smoke bush a very attractive ornamental. It produces prolific stump sprouts as well as root suckers.

The smoke bush is a native of southern Europe south of the Carpathians and of southern Siberia, its range extending to China. It grows on dry, mostly south-facing banks in thin oak and pine woods. A light-loving shrub, it stands up well to dry spells and tolerates soils containing lime and magnesium. In central and western Europe it is widely planted in parks as a specimen plant for its ornamental reddish fluffy fruiting clusters and crimson autumn foliage. It may be damaged by frost in severe winters.

The wood is the heaviest and hardest of European woods and is used in wood carving and for inlay as a substitute for ivory; it is also used in industry to make shuttles for textile looms.
