The leaf at the base of the stem is narrow in shape, reaching up to 30 centimetres (12 in) long, and withering away at flowering. The inflorescence bears 1 to 4 erect bell-shaped flowers. Each flower has three sepals and three petals up to 4 centimeters long. The petals are rounded in shape and white to pink in base color with a central spot or streaking of red, purple, and yellow. The fruit is a narrow capsule up to 6 centimeters long. (contributed by Mary Ann Machi)
