Perennial plants growing from small bulbs about 2 cm long.
Bulbs have thin roots and stolons (long, horizontal stems) on which new bulbs form.
About 4 – 6 flat, grey-green grass-like leaves that are up to 30 cm long.
Leaves appear before the flowers.
Bulbs and leaves have an oniony smell when damaged.
Each bulb can have numerous inflorescences over a 6 to 8 week period.
The leafless stalks (scapes) are up to 20 cm high and have one flower.
The bract has purplish stripes.
The star-shaped flowers are about 3 cm long.
The 6 tepals, in 2 whorls, have the bases fused into a purplish tube.
The tepal lobes flare outwards so the flower is 3 to 4 cm across.
Mostly white or pale blue but cultivars include deeper blue, pink and purple.
Tepal lobes have a blue or purplish line (midrib) most prominent on the backs of the lobes.
The stamens, with yellow anthers reach the top of the perianth tube.
