Northern borders: The black nightshade (Solanum nigrum) plant has recently been observed in several locations across Northern Borders Region as part of the region's seasonal vegetation.

According to Saudi Press Agency, black nightshade is an annual herbaceous plant in the family Solanaceae, typically growing in fields and along waterways, reaching up to one meter in height. The plant features flat leaves and clusters of small white flowers, each containing four to 10 blossoms.

The berries start green and ripen to black or dark blue, becoming juicy and sweet, with numerous small, kidney-shaped seeds.

Black nightshade contains chemical compounds such as solanine, asparagine, lutein, tannins, linoleic acid, and palmitic acid.
