Calostemma

Family: Amaryllidaceae
Common Name: Garland Lily

An Australian native from the plains of Queensland, New South Wales, Victoria and South Australia, this single-species genus of bulbous plants produces terminal clusters of trumpet-shaped, lily-like flowers on upright stems. It has narrow, strap-shaped, fleshy leaves similar to those of the snowdrop. The foliage dies down every year and appears again when flowering is complete. It is not often grown in the UK.

Species

C. purpureum, garland lily, is a very striking species, with its mass of small, trumpet-shaped, reddish purple to pink flowers balancing on its sturdy, erect stems 80 cm (32 in) in length. It has dark green, fleshy, strap-like leaves to 30 cm (12 in), which appear after flowering.

Cultivation

In climates prone to hard frosts, grow in pots in a cool greenhouse, using a well-drained, soil-based potting compost. Outdoors, Calostemma likes moist conditions but also does well on rock gardens. Propagate from the fleshy seeds contained in the capsular fruits. Even established plants can be transplanted easily, or they can be divided in early spring.

Climate
