Atropa belladonna, commonly known as belladonna or deadly nightshade, is a toxic perennial herb native to woodland edges, clearings, and coastal scrub in Europe, North Africa, and Western Asia. It thrives in calcareous, nutrient-rich soils but can also be found in disturbed areas. Belladonna grows up to 7 feet tall and has a branching habit. The plant bears dull purple, bell-shaped flowers from June to August, which are followed by shiny black berries. The foliage is dark green, and the overall appearance is both alluring and menacing due to its toxicity.

Belladonna is known for its striking berries and historical significance. While it is not commonly cultivated due to its poisonous nature, it is occasionally grown in witch gardens or for educational purposes in botanical gardens. In cultivation, it requires moist, well-drained soil, partial shade to full sun, and regular watering. It is not typically prone to diseases but can be affected by fungal infections in overly wet conditions. Belladonna contains tropane alkaloids, which are highly toxic and can cause delirium, hallucinations, and even death if ingested. Due to these compounds, it has been used historically as a medicine for its anticholinergic properties, as a cosmetic to dilate pupils, and infamously as a poison.CC BY-SA 4.0
