Tagetes erecta

Tagetes erecta, the Mexican marigold, also called Aztec marigold, is a species of the genus Tagetes native to Mexico and Central America. Despite its being native to the Americas, it is often called African marigold.  In Mexico, this plant is found in the wild in the states of San Luis Potosí, Chiapas, State of México, Puebla, Sinaloa, Tlaxcala, and Veracruz. This plant reaches heights of between 50–100 cm (20–39 in). The Aztecs gathered the wild plant as well as cultivating it for medicinal, ceremonial and decorative purposes. It is widely cultivated commercially with many cultivars in use as ornamental plants, and for the cut-flower trade.

Although not very frost resistant, it can be grown as a tender annual in Britain, sowing the seed in a greenhouse in the spring and planting out after the last expected frosts. 

The flowers are often sold in local markets in Nepal and used as an offering to the Gods. A number of named forms have been developed for their ornamental value. The cultivar 'Yellow Climax' has mild flavoured edible flowers that can be used as colourful garnishes. All parts of the plant emit an unpleasant smell similar to that of stale urine when they are bruised. Removing dead flowers before the seed is formed will extend the flowering season.
