Mexican aster (Eng.), Kosmos (Afr.)
Cosmos is a genus of about 25 species of erect to spreading, freely branched annuals and perennials found in scrub and meadows. The annual species C. bipinnatus are commonly grown in gardens on mass for the showy flowers. Cosmos was introduced to South Africa via contaminated horse-feed imported from Argentina during the Anglo-Boer War. It is now widespread over the high eastern plains of South Africa and invasive in certain areas.
