Perennial herbs (grow for several years from their same root system) found under evergreen trees or shady areas in mountains. Long vines grow underground and often found in clusters. The Japanese name Ooba-jyano-hige literally meaning large leaf beards of snakes was named because leaves resemble beards of snakes and this plant has wide and thick leaves compare to other plants in ophiopogon genes. Leaves grow from roots are elongated and 20 to 40 cm long. Have shiny surface but edges are rough. Flowers are 6 to 7 mm long and white or light purple. In Mt. Takao, white ones are more often found. Slightly curved flower stems are facing downward and bloom from the bottom ones. Skin of fruits drop at early stage and seeds are not covered with anything. Become grayish dark green when ripen.
