Black nightshade can be grown almost anywhere in South Africa, even under marginal conditions. The young leaves and shoots are used as fresh vegetables, and the fruit is edible and tasty.
Black nightshade (Solanum retroflexum) is an annual herb that grows up to 75cm high. It has a slender tap root, a purplish green stem, and greyish green leaves. The flowers are white with a yellow centre.
The seeds are about 2mm long and light brownish-yellow or purple in colour. The berries are between 5mm and 12mm in diameter; they are green when immature and become purplish-black when ripe.
Black nightshade grows best at a temperature of between 20°C and 34°C. It prefers full sunlight, but can grow in partial shade. It is sensitive to frost.
Soil requirements
Nightshade can grow in light, medium or heavy soil provided the soil is rich in nitrogen, phosphorus and organic matter.
