The flowers are white, sometimes with pink tinges or occasionally all pink, and are arranged in groups of two to four on a stem (scape) that is about as long as or longer than the leaves. Each flower is borne on a long stalk (pedicel), up to 45 or 60 mm long, and has six tepals, 12–20 mm long, with sharp tips, that open widely to form a bell shape. The two spathes are shorter than the pedicels.
