Characteristics

Branching annual, 1.5–6 dm, glabrous, or somewhat strigose or incurved-puberulent especially above; lvs petiolate; ovate to deltoid, irregularly blunt-toothed or subentire, 2–8 × 1–5.5 cm; peduncles numerous, ascending, to 3 cm, the pedicels closely clustered (forming an umbelliform infl), mostly deflexed at least in fr; mature cal 2–3 mm, the lobes often unequal, sometimes reflexed; cor white or faintly bluish, 5–10 mm wide; frs globose, black, 8 mm, poisonous at least when young, many-seeded and often with 1–10 subglobose concretions to half as long as the seeds; polyploid series based on x=12. A cosmopolitan weed of disturbed habitats, highly diversified, but not yet satisfactorily resolved into discrete taxa, in spite of many attempts. The native N. Amer. plants, as here described, are all diploid, so far as known; the oldest name for these at the specific level may be S. ptychanthum Dunal (S. americanum Mill., probably misapplied). At the varietal level the name would be S. nigrum var. virginicum L. Typical European S. nigrum is only casual with us, mainly about our large Atlantic ports. It is hexaploid and more pubescent (the hairs short, ± spreading and somewhat viscid), with a more nearly racemiform (but still compact) infl.

Environment

It is a temperate and tropical climate plant. They occur in waste places at low and medium altitudes throughout the country. It grows from sea level up to high altitudes such as 2700 m in the tropics. It often comes up self sown after fires. It is grown in most tropical countries as a green leafy vegetable. It occurs between 600-3000 m in southern China. In Nepal it grows to about 2900 m altitude. It can grow in areas with an annual rainfall below 500 mm. It can grow in arid places. Tasmania Herbarium. In Sichuan and Yunnan.

Usage

The ripe fruit are cooked and eaten. They are also used for soup. They can be stewed or made into pies, jams, preserves, puddings, sauces, pastry and a spicy relish. They are also used for chutney. Ripe fruit are eaten. The leaves and young shoots and flowers are eaten cooked. They should be BOILED. The harvested leaves can be stored for 2-3 days. CAUTION: The fruit can contain the alkaloid Solanine probably when unripe. This gets destroyed with boiling.

Cultivation

It is grown from seed. In the tropical highlands areas it is almost always self sown or encouraged by burning grassland but then weeded and harvested as a normal component of the garden. In coastal areas seeds are sown by broadcasting. Good yields can be obtained under moderate fertility levels. A spacing of 40 cm x 40 cm is suitable. Topping encourages branching. It can be grown from cuttings. Plants are also grown in nurseries and transplanting.
