The leaves are long and narrow, up to 11 centimetres (4 in) wide, folded lengthwise near the base and pleated along the veins or flat near the top. Flowers are 6.5 centimetres (2.6 in) long, in the shape of a star with 6 blue-violet or blue pointed petals and sepals. 1 or 2 flowers emerge from a common spathe, or sheath. Each flower lasts only one day, opening up in the late morning and closing mid-afternoon.
