Gloriosa is a genus of five or six species in the plant family Colchicaceae, from tropical Africa and Asia. The most common English names are flame lily, fire lily, gloriosa lily, glory lily, superb lily, climbing lily, and creeping lily. They are tender, tuberous rooted deciduous perennials, adapted to summer rainfall with a dormant dry season. Their native range is Africa, Southeastern Asia and parts of Malaysia, but they are now widely cultivated. All parts of the plant contain colchicine and related alkaloids and are therefore dangerously toxic if ingested, especially the tubers; contact with the stems and leaves can cause skin irritation.
Gloriosa superba is the national flower of Zimbabwe. It is also the state flower of Tamil Nadu state in India, and was the national flower of Tamil Eelam, and as such was displayed during Maaveerar Day.
