In summer, the Japanese knot can grow from 10 cm per day to 4 meters. The undergrowth continues its territorial game with a dense population with bamboo stems that are hollow and green with red spots.

Its leaves have a characteristic shape with a pointed tip and a straight edge.

Flowers begin to bloom for the Japanese goat in early fall. Small white flowers germinate until the end of the season when the stems die off, leaving the plant inactive.

In winter, the stems of this plant become dark brown or red. Outbreaks may be dormant, as if they are waiting the next possible season. Dry stalks or canes remain; It may take three years before complete decomposition occurs.
