Allamanda, also known as Yellow Bell or Golden Trumpet, is a genus of tropical shrubs or vines with hairy seeds, native to South and Central America. A shrub or Bush is a horticultural rather than strictly botanical category of Woody plant, distinguished from a Tree A vine is any plant of Genus Vitis (the Grape plants or by extension any similar climbing or trailing plant South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a Their year-round production of large, bright flowers have made the Allamanda popular ornamentals. Allamanda belongs to the dogbane family (Apocynaceae).

Usually woody, evergreen shrubs with vigorous growth, Allamanda may reach a free-standing height of 2 metres or more. The leathery leaves are lancelike, pointed, and may either be opposite or in whorls of three or four. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. The yellow, trumpet-shaped flowers are 5-7. 5 cm in diameter; cultivated forms have been selected for larger flowers which may also be white, purple, pink or orange in colour. Their scent may be described as delicate and fruity.

In the wild, Allamanda grow along riverbanks and other open, sunny areas with adequate rainfall and perpetually moist substrate. The plants do not tolerate shade, nor do they tolerate salty or alkaline soils; they are highly sensitive to frost. Allamanda are otherwise undemanding and with appropriate conditions will grow rapidly, from 1-3 metres annually. The seed capsules are oval and prickly; cultivated forms rarely produce seeds, but Allamanda are easily propagated from cuttings. Discarded cuttings are quick to take root.

Allamanda have become naturalized throughout the tropics; they may be seen in roadside ditches, abandoned yards and dumps. As a controlling measure, cutting is ineffecive with Allamanda and will lead to vigorous coppicing. Owing to its fast growth, Allamanda has been introduced widely where it is used as a groundcover or for hedges and screens. Groundcover is a Plant used for the purpose of growing over an area of ground to hide it or to protect it from erosion or drought In some areas Allamanda are an invasive species, notably Allamanda cathartica in Queensland, Australia.

Allamanda cathartica is also notable for its medicinal properties: all parts of the plant contain allamandin, a toxic iridoid lactone. Iridoids are a class of Secondary metabolites found in a wide variety of plants and in some animals lactone is a cyclic Ester in Organic chemistry. It is the condensation product of an Alcohol group and a Carboxylic acid The leaves, roots and flowers may be used in the preparation of a powerful cathartic (hence the name); the milky sap is also known to possess antibacterial and possibly anticancer properties. Laxatives (or purgatives) are foods compounds or drugs taken to induce bowel movements or to loosen the stool most often taken to treat Constipation. Antiseptics (from Greek αντί - anti, '"against" + σηπτικός - septikos, "putrefactive" are antimicrobial Chemotherapy, in its most general sense refers to treatment of disease by chemicals that kill cells specifically those of micro-organisms or Cancer. Gardeners exposed to the sap will develop rashes, itch, and blisters.

The genus name Allamanda derives from Dr. Frédéric-Louis Allamand (1735-1803), a Swiss botanist of the late 18th century. Frédéric-Louis Allamand (~ February 5 1736 - after 1803 was a Swiss Botanist.
