Answer 3

Atropa belladonna or Atropa bella-donna, commonly known as belladonna or deadly nightshade, is a perennial herbaceous plant in the family Solanaceae. The drug atropine is produced from the foliage, which along with the berries are extremely toxic, with hallucinogenic properties.

The species is native to Europe, North Africa, and Western Asia, and has become naturalized in parts of North America. In areas where it has become naturalized it can often be found in shady, moist areas with a limestone-rich soil. The name bella donna is derived from Italian and means "beautiful woman."[1]

Atropa belladonna is a branching herbaceous perennial, often growing as a subshrub, from a fleshy rootstock. Plants grow to 1.5 m (5 ft) tall with 18 cm (7 in) long ovate leaves. The bell-shaped flowers are dull purple with green tinges and faintly scented. The fruits are berries that are green, approximately 1 cm in diameter and when ripe, turn black with a shiny sheen. The berries are sweet and are consumed by animals that disperse the seeds in their droppings, even though the seeds contain toxic alkaloids. [2] There is a pale yellow flowering form called Atropa belladonna var. lutea with pale yellow fruit.

Atropa belladona is rarely used in gardens, but when grown it is usually for its large upright habit and showy berries.[3] It is considered a weed species in parts of the world,[4] where it colonizes areas with disturbed soils.[5] Germination of the small seeds is often difficult, due to hard seed coats that cause seed dormancy. Germination takes several weeks under alternating temperature conditions but can be speed up with the use of gibberellic acid.[6] The seedlings need sterile soil to prevent damping off and resent root disturbance during transplanting.
