Black NightshadeWith its white flowers with their striking yellow stamens, Black Nightshade is a striking plant of waysides, waste ground and cultivated land, which occasionally makes its way into gardens. Native to the UK it is more common in the south than the north.

One way to distinguish Black Nightshade from its more toxic cousin, Deadly Nightshade (Atropa belladonna), is by the berries, which are borne singly on the latter but in bunches on the former. That isn’t to say that Black Nightshade doesn’t contain toxins. Its toxicity is in fact very variable, and some strains are in fact cultivated as a food crop, while it has a long history of use in herbal medicine across many cultures. However, the unripe (green) fruit contains the toxin solanine, so the plant should be avoided as a food plant unless you are an expert forager and can identify different strains of the species.

…Two sub-species of S. nigrum are found in Britain, S. nigrum ssp. nigrum, and S. nigrum ssp. schultesii. The former is more common, while the latter is mainly found in southeastern England.

… Nightshades are in the same family as tomatoes and potatoes.
