Solanum is a large and diverse genus of flowering plants. The generic name was first used by Pliny the Elder for a plant also known as strychnos, most likely Solanum nigrum. Its derivation is uncertain, possibly stemming from the Latin word Sol, meaning sun, referring to its status as a plant of the sun. Solanum kitagawae is a species native to Russia, China, Japan, Mongolia, Afghanistan. Known as: Solanum borealisinense, Solanum depilatum. All parts of the plant are poisonous, containing solanine, which can cause convulsions and death. Solanine has pesticidal properties, and it is one of the plant's natural defenses.
