Derivation of name and historical aspects
The genus name is derived from Greek words krokos meaning saffron and osme meaning smell. This came about because when dried flowers are placed in warm water, they emit a strong smell of saffron. The species name is derived from a Latin word aurea meaning golden, which refers to the flowers.
The main characteristics of the genus Crocosmia is that the flower lobes are spreading and the plants are dormant in winter. There are nine species in this genus, and seven of them occur in South Africa.
Uses and cultural aspects
It contributes significantly in its environment, as its seeds are eaten by birds and bush pigs feed on the corms. It is also used in traditional medicine to treat dysentery.
