The flowers are produced in a capitulum with a ring of broad ray florets and a center of disc florets; flower color varies noticeably between the different species. The genus includes several ornamental plants popular in gardens. Numerous hybrids and cultivars have been selected and named.

Distribution
Cosmos species are native to scrub and meadowland in Mexico where most of the species occur. In the United States , some varieties may be found as far north as the Olympic Peninsula in Washington, but the range also extends through Central America to South America as far south as Paraguay[citation needed]. One species, C. bipinnatus, is naturalized across much of the eastern United States and eastern Canada.[5]
It is also widespread over the high eastern plains of South Africa , where it was introduced via contaminated horsefeed during the Anglo-Boer War.[6]

"The South African Light Horse, having no baggage train and living largely off the country, were able to range widely across Natal. How widely can be seen from the spread of the beautiful pink cosmos flower, a native of Argentina which was imported into South Africa in the British Army's horse fodder. Just as cairns on the battlefields mark where soldiers fell, so their route is marked by the pink swathes of cosmos. As my children picked bunches of these lovely flowers for me I wondered if the seeds from which they originated had germinated in the belly of my grandfather's horse as he had ridden that way."
