Definition

Noun: 1. A poisonous plant: A Eurasian herb (specifically, Solanum dulcamara), also known as bittersweet or woody nightshade, naturalized in America. It is characterized by white or purple flowers, hairy and potentially poisonous foliage, and clusters of berries that are black when ripe. These berries are sometimes poisonous and sometimes considered edible, depending on the stage of ripeness and individual sensitivity.

Examples
  • The poisonberry vine climbed over the old fence, its dark berries contrasting with the yellow autumn leaves.
  • Hikers are warned not to eat the attractive black berries, as they might be from a poisonberry plant.
  • The poisonberry's flowers are star-shaped and can be white or violet.
Advanced Usage
  • The term poisonberry is often used in botanical and ecological contexts to describe this specific invasive species and its dual nature of being both toxic and, in certain contexts, used in traditional medicine (with extreme caution).
  • It serves as a common name that highlights the plant's primary risk characteristic (poison) and its fruit type (berry).
Variants and Related Words
  • Bittersweet (n): A common name for the same plant (), referring to the taste of its stems.
  • Woody nightshade (n): Another common name for this plant, distinguishing it from the more deadly "deadly nightshade" ().
  • Nightshade (n): The broader plant family (Solanaceae) to which the poisonberry belongs, which includes tomatoes, potatoes, and peppers, as well as many toxic plants.
Synonyms
  • Bittersweet
  • Woody nightshade
  • (scientific name)
Notes on Meaning

The defining characteristic of the poisonberry is its ambiguity and potential danger. While the berries are sometimes described as edible for birds or in folk remedies, they contain solanine and other alkaloids that can be toxic to humans, especially when unripe. Therefore, the name accurately reflects the primary caution associated with the plant. It is not typically used to refer to other unrelated poisonous berries, which have their own specific names (e.g., belladonna berries, pokeweed berries).

Noun
  1. Eurasian herb naturalized in America having white flowers and poisonous hairy foliage and bearing black berries that are sometimes poisonous but sometimes edible
