Jimson weed / Datura

Datura stramonium

Description:

D. stramonium is a foul-smelling, erect annual, freely branching herb that forms a bush up to 2 to 5 feet (60–150 cm) tall. The root is long, thick, fibrous and white. The stem is stout, erect, leafy, smooth, and pale yellow-green. The stem forks off repeatedly into branches, and at each fork forms a leaf and a single, erect flower. The leaves are approximately 3 to 8 inches (8–20 cm) long, smooth, toothed, soft, irregularly undulate. The upper surface of the leaves is a darker green, and the bottom is a light green. The leaves have a bitter and nauseating taste, which is imparted to extracts of the herb, and remains even after the leaves have been dried. Datura stramonium generally flowers throughout the summer. The fragrant flowers are trumpet-shaped, white to creamy or violet, and 2 1⁄2 to 3 1⁄2 inches (6–9 cm) long, and grow on short stems from either the axils of the leaves or the places where the branches fork. The calyx is long and tubular, swollen at the bottom, and sharply angled, surmounted by five sharp teeth. The corolla, which is folded and only partially open, is white, funnel-shaped, and has prominent ribs. The flowers open at night, emitting a pleasant fragrance and is fed upon by nocturnal moths. The elliptic seed capsule is 1 to 3 inches (3–8 cm) in diameter and either covered with spines or bald. At maturity it splits into four chambers, each with dozens of small black seeds.

Habitat:

Datura stramonium is native to North America, but was spread to the Old World early. It was scientifically described and named by Swedish botanist Carl Linnaeus in 1753, although it had been described a century earlier by herbalists, such as Nicholas Culpeper. Today, it grows wild in all the world's warm and moderate regions, where it is found along roadsides and at dung-rich livestock enclosures. In Europe, it is found as a weed on wastelands and in garbage dumps. The seed is thought to be carried by birds and spread in their droppings. Its seeds can lie dormant underground for years and germinate when the soil is disturbed. People who discover it growing in their gardens, and are worried about its toxicity, have been advised to dig it up or have it otherwise removed.

Notes:

This is very dangerous plant, considering the fact that every little bit of the plant is highly toxic. But at long summer nights it gives sweet smell that is mesmerazing.
