Description edit

Flowers are produced sporadically during late summer and autumn, singly on stems 10 to 20 centimetres (4 to 8 in) tall. Flowers are usually yellow with copper tones on the outside, with tepals about 3 centimetres (1.2 in) long, fused for a short distance at the base to form a tube. As with all former Habranthus species, the flowers are not upright on the stem but held at a slight angle. The leaves are not normally present at flowering time, appearing later; they are narrowly linear.[3]

Chemical composition edit

Contains toxic lycorine.[4]

Cultivation edit

Zephyranthes tubispatha tolerates some frost down to 0 °C (32 °F) if planted in a sheltered sunny position, but will not survive being frozen. It seeds freely. A form with pinkish flowers is grown as var. rosea, but may be a hybrid.[3]

Z. tubispatha has gained the Royal Horticultural Society's Award of Garden Merit.[2][5] The name Habranthus andersonii is commonly found in horticultural sources.
