Overview
It occurs in a very wide range of habitats, from woodlands to scrubland, hedges and marshes.
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. The flowers are in loose clusters of 3–20, 1–1.5 cm across, star-shaped, with five purple petals and yellow stamens and style pointing forward. The fruit is an ovoid red berry about 1 cm long, soft and juicy, with the aspect and odour of a tiny tomato, and edible for some birds, which disperse the seeds widely. However, the berry is poisonous to humans and livestock, and the berry's attractive and familiar look makes it dangerous for children.
It has a long flowering season and can flower from May through November.Its fruit persists for an average of 19.5 days, and bears an average of 17.9 seeds per fruit.

Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 31, 2026. The linked authority identifier is Q147707. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
