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.[4] 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.[3] Each flower lasts only one day, opening up in the late morning and closing mid-afternoon.[5]
