Watsonia is a genus of plants in the iris family, subfamily Crocoideae, native to South Africa. The genus is named after Sir William Watson, a British botanist. There are 52 species in southern Africa; all are perennial herbs growing from corms and producing erect spikes of showy flowers, and are adapted to a mediterranean-type climate. The most common species in cultivation is the pink-flowered Watsonia borbonica and its white mutant ‘Arderne’s White’. These were crossed with Watsonia meriana and other species in the early 20th century by breeders including John Cronin in Australia and Luther Burbank in California to produce a wide range of cultivars. Watsonia has been eclipsed in popularity by Gladiolus and other bulbs, and is now neglected by the nursery industry. In the South-West of Western Australia, six species have become naturalised from garden escapes along rivers, wetlands and seasonally wet ground.

Watsonia bachmannii is a very rare range restricted South African endemic perennial geophyte found in the Eastern Cape and KwaZulu-Natal provinces from Umtamvuna to Mkweni River, growing in Pondoland coastal grassland, Msikaba Formation Sandstone, in seepages and vleis, but also in open grassland and among rocks at altitudes of 50-500 m. During spring appears the eye-catching orange flowers.
