Solanum dulcamara or Climbing Nightshade is a perennial climbing vine known for its attractive purple-blue flowers, which bloom from June to September, and its red or purple berries. While the flowers pose no health risks, ingesting the berries is toxic to humans and animals. Still, it is not recommended to consume the flowers since some may have traces of toxic compounds.
Climbing Nightshade is native to Europe and Asia but has also spread to other regions and is considered a weed in many areas. Climbing Nightshade can reach up to 32 feet (10 m) in length. It has green or purplish stems that are four-angled and slightly hairy. The leaves are alternate, simple, and oval-shaped, and have smooth or somewhat hairy surfaces. The flowers are small, star-shaped, purple-blue to violet in color, and usually found in clusters of 1-3. They bloom from June to September. The berries are small, round, red or purple, and are arranged in clusters. They ripen from August to October. Ingesting berries is poisonous for humans and animals.
