Black Nightshade


 

Nightshades or Solanaceae are known for having a diverse range of alkaloids. To humans, these alkaloids can be desirable, toxic, or both. Plants containing these substances have been used for centuries as poisons. However, despite being recognised as poisons, many of them have invaluable pharmaceutical properties or value as food.

The Black Nightshade (Solanum Nigrum) competes vigorously for space, sunlight, soil moisture and nutrients. Its seeds are spread by birds and other animals which eat the juicy, dark purple berries.

Snails and slugs are attracted to the Black Nightshade. It is a host for diseases including blight, leaf spot and powdery mildew, nematodes, bacterial diseases, fungal diseases and crop viruses.

The entire plant is considered toxic, however ripe berries are usually harmless. Eating green berries may cause headache, nausea and stomach upset.
