Holly Shrub

By Jada Aaron

Bladder senna is a 1-3 m shrub with slightly pendent shoot tips. One-year shoots are slightly angular and coloured greenish grey. The small buds are located behind the remainder of the leaf sheath. The bladder senna resembles the pea tree but can be readily distinguished by the odd number of leaflets (those of the pea tree being even).

Its range of natural distribution embraces central and southern Europe, extending eastward as far as the Caucasus. It grows in broadleaved forests in hilly country in moist locations with good, lime-rich soil. Nowadays it is comparatively rare in the wild, being found more frequently in parks. It is best propagated by means of seeds, which as a rule do not germinate until the second year. The bladdernut has attractive foliage as well as flowers. It thrives in sun or partial shade.

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.

This shrub's range of distribution extends northward to the Baltic Sea. It is most plentiful on moist rich soils in valleys bordering brooks, on the edges of forests, in hedgerows and in light woodlands because it is a plant that requires partial shade. It is best propagated by seeds. The leaves turn scarlet in the autumn and these, as well as the fruits, make it very attractive at this time.

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. - 15266
