The Dayflower is so called because the flowers only open for a day. It grows erect to about a foot high with wide, grass-like leaves clasping the stem. Leaves have parallel veins and reddish edges. The unusual flowers are showy and grow from a spathe, a folded, sickle-shaped, purse-like bract. If the spathe is squeezed, it produces a drop of liquid, hence another common name, Widow's Tears. The flowers are about one inch across with two roundish, bright blue petals side by side and a small, white, notched petal below. The flowers, young leaves and stems are edible. In China, Dayflowers are often grown as a leafy vegetable crop as it is popular in a number of localized dishes. Within parts of Asia, the Dayflower also has a long history of use as a medicinal plant from treating throat infections to fevers. Source.
