Watsonia
Tall, showy corm plants from southern Africa, known as bugle-lilies
Watsonia is a group of perennial plants with upright spikes of colourful flowers, native to southern Africa. Grown from corms, these plants are often found in fynbos and mountain areas, and have been widely cultivated and naturalised in places like Australia.
- Watsonia is native to South Africa, Lesotho, and Eswatini.
- There are about 58 species of Watsonia.
- Watsonia borbonica is the most commonly cultivated species.
- Six species have become naturalised in Western Australia.
- Watsonia grows from corms and produces tall spikes of showy flowers.
What does Watsonia look like?
Watsonia plants are perennial herbs that grow from corms, forming upright spikes of large, showy flowers. The blooms are most commonly pink or white, with some cultivated varieties showing other shades. Their leaves are long and sword-shaped, and the plants can reach impressive heights in the right conditions. The flowers are arranged along tall stems, giving a striking vertical accent in gardens or wild landscapes.
Where does Watsonia come from?
Watsonia is native to southern Africa, especially South Africa, Lesotho, and Eswatini. Most species grow in fynbos, a type of Mediterranean-climate shrubland, but some adapt to wetter or more continental climates, including mountains and marshy flats. The genus was named for Sir William Watson, a British botanist. Watsonia was introduced to Australia as a garden ornamental in the 19th century and has since spread to other regions, sometimes becoming naturalised.
When and how Watsonia blooms
Watsonia plants grow from corms, which are planted in the ground. They thrive in climates with wet winters and dry summers, but some species tolerate summer rainfall. The plants send up long, sword-like leaves and, in season, tall spikes of flowers. Gardeners have bred many cultivars, especially from Watsonia borbonica and Watsonia meriana, to create a range of colours and forms.
How Watsonia is used
Watsonia is mainly grown as a garden ornamental for its tall, colourful flower spikes. In some regions, especially Australia and New Zealand, it has escaped gardens and become established in the wild, sometimes as a weed. It is less popular in the nursery trade today, having been overtaken by other bulbs like Gladiolus.
Kinds of Watsonia
There are about 58 species of Watsonia, with Watsonia borbonica and its white form 'Arderne's White' being especially well known in gardens. Breeders have created hybrids and cultivars by crossing different species, leading to a wide variety of flower colours and forms. Some species, such as Watsonia meriana var. bulbillifera, are notable for their ability to spread rapidly.
What Watsonia means
Watsonia does not have a strong symbolic or religious meaning in the sources, but it is valued for its beauty in gardens and landscapes. In some places, it has become a weed, displacing native plants and creating fire hazards. Its role in horticulture has faded compared to other bulbs, but it remains a part of southern African flora and garden history.
