Flowers are at the end of stalks that arise from leaf axils near the top of the plant. Individual flowers are ½ to 1 inch across and have 3 petals. The upper 2 petals are round and bright blue, the lower petal is much smaller, white and notched into 3 rounded lobes. There are 3 long fertile stamens and 3 short sterile stamens, each with yellow tips and often a spot of reddish brown in the center.
Behind the flower is a pair of leafy bracts (spathe) that is up to 2 inches long. The spathe is fused at the bottom and open at the top all the way to its base. Each flower lasts for a single day, hence the common name.
Leaves are up to 5 inches long and 2 inches across, toothless, hairless, with pointed tips, a rounded base and no leaf stem. There are faint parallel lines along the length. There is a mostly hairless sheath up to 1 inch long where the leaf joins the main stem. The main stem is smooth and hairless.
