Bladdernut

By Jada Aaron

The bladdernut is an upright, tree-like shrub, 2-5 m high. The bark covering the stem is greenish brown with whitish longitudinal stripes. The shoots are stout and green with paired green buds at the tip of the twig, as a rule, covered with a single fused pair of scales. The whitish, drooping flowers, 5-12 cm long, appear in May-June, the round bladder-like fruits, measuring 2-3 cm, ripen at the end of September and beginning of October. They are 2- or 3-valved, with each compartment containing a single, light brown, hard, round seed the size of a pea. At one, time the seeds were used to make rosaries.

The yellow flowers are striped brownish-red at the base of the standard and have a persistent, many-pointed calyx. They appear in succession from May to June. The bladder-like seed pods, which ripen from late summer and from which the shrub takes its name, contain 30-40 kidney- shaped, markedly flattened, blackish-brown seeds, which are a good and easy means of propagation. It is recommended, however, to immerse the seeds briefly in hot water before sowing so that they will germinate uniformly.

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 common box is a broad shrub or small tree 4-8 m high. The twigs are square in cross section and covered with dense foliage. The inconspicuous blossoms appear in April. The, female flower is situated in the centre of the cluster of male flowers. The woody capsules ripen in autumn, when they split and eject several glossy black seeds. It is a slow-growing plant but may live to an age of several hundred years. It produces abundant sprouts and stands up well to pruning.

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.

Farmers do not welcome its presence in the vicinity of fields because it serves as host to the black or bean aphis, which causes great damage to bean and sugar beet plantings. There are several garden varieties of which `Albus' with white fruits, 'Red Cascade' with red fruits and `Atropurpureus' with dull purple leaves are noteworthy.
