Solanum dulcamara, commonly known as bittersweet nightshade, is a perennial vine native to Europe and Asia. It features purple flowers and small, red berries, which are toxic if ingested. The plant typically grows in moist, disturbed areas and can climb over other vegetation, making it a vigorous grower. This species belongs to the Solanaceae family, which includes other plants like tomatoes and potatoes. While it has been used in traditional medicine, caution is advised due to its toxic properties. Solanum dulcamara can also be invasive in some regions, outcompeting native plants for resources.
