Solanum dulcamara is a semi-woody herbaceous perennial vine, which scrambles over other plants, capable of reaching a height of 4 m where suitable support is available, but more often 1–2 m high. The leaves are 4–12 cm long, roughly arrowhead-shaped, and often lobed at the base.

Because wetland ecosystems are so important to climate health overall, presence of climbing nightshade could potentially prove harmful. S. dulcamara should be monitored in the OLL in spring and summer to ensure it is not becoming invasive, …

Climbing nightshade is an invasive perennial vine that colonizes waste areas and stream banks, sometimes growing across small streams and affecting hydrology. All parts of the plant are toxic, including the bright red fruits.

Climbing nightshade, especially in its green immature fruits, contains steroidal alkaloids, which have caused poisoning in cattle and sheep. Humans may have been poisoned after ingesting immature berries. Recent experiments show that the mature red berries contain only a small amount of toxin and have little chance of harming children.

Climbing nightshade occurs in upland mesic deciduous forests with a similar composition of overstory species and with other deciduous trees that may be more characteristic of mesic sites such as American beech (Fagus grandifolia), northern red oak (Quercus rubra), and slippery elm (Ulmus rubra) [10,11,27,35,45,85].
