Calostemma is a small genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae). It consists in 3 species endemic to Australia, where they are distributed in arid regions with summer precipitations. They are known as "Wilcannia Lily".
Members of Calostemma often flowers in a leafless state, the narrow, shining-green, strap-like leaves usually preceding flowering and reaching a length of 25-30 cm. Blooms are borne in an umbel of six to eighteen flowers on a scape, 20-50 cm high. Flower colour is a purplish red or yellow with a tube sometimes paler and the anthers yellow. Each trumpet-shaped flower is held on a long, thin pedicel and is about 2 cm long.
- Calostemma abdicatum P.J.Lang, distributed in South Australia.
- Calostemma luteum Sims, from Center Queensland to South Australia.
- Calostemma purpureum R.Br., South Central and South Eastern Australia.
Due to their large and showy flowers, members of this genus are used as ornamental plants. Seeds germinate on the plants and should be sown in a well-drained mix, placed in a warm spot and protected from snails and slugs. It flowers best after dry periods so should be allowed to dry off after the leaves yellow. Growth is improved by the application of slow released fertilizer.
