It germinates around spring and grows about 49 to 0.9 cm in height until summer. It has long oval leaves resembling myoga, and the roots of the leaves form a leaf sheath that winds around the stem. Leaves concentrate only on the tip of the stem. The leaves of this species can be distinguished from myoga by the fact that the surface is rough, and the leaves do not appear in two rows. Around summer, the inflorescences shoot up from the tip of the stem, and white flowers bloom. There are amphoteric flowers and male flowers. The former can be discerned where white female wings stand out, and the latter can be distinguished by the yellow buds. There are 3 white petals, 3 white buds, 6 male buds, and 1 female bud, and the diameter of the corolla is about 8 mm. When the flower is over, it will have a spherical fruit with a diameter of about 5 mm until early autumn, and will soon drop its leaves. In fact, it is green when young and dark blue-purple when it ripens.
