Plant description

Clump-forming herb with globular bulb to 6 cm diameter. Leaves, several, linear, flat to 60 cm long and 18 mm wide, developing after the flowering. Flower-head terminal on a long stalk with 10-30 purple tubular flowers in the umbel. Flowering between January and April. Calostemma luteum intergrades with C. purpureum along the Murray River producing various colour forms but can be distinguished by the generally larger flowers with more widely spreading petals and predominately yellow flower colour, with fewer scape bracts. Fruits are globular capsule to 1 cm diameter with a few seeds in each.

Seed collection and propagation

Collect seeds between March and June. Collect mature capsules off the plant or on the ground next to the plant. No cleaning is required if only seeds are collected. However, seeds can not be stored long term. Seeds are recalcitrant, that is they do not survive drying and freezing and cannot be stored long term for ex-situ conservation. Seeds are recalcitrant and will germinate readily.
