The flowers of Lamiaceae are mostly grasses, but this one is unusually a tree. It grows naturally on the forest floor in the low mountains to mountains west of central Honshu. The underside of the leaf is densely covered with stellate hairs. The flower spikes bloom upward from the bottom. The flower spikes (inflorescences) grow from the tips of the stems in early autumn. Each bract contains two or three small flowers contained in a calyx. The calyx and corolla are tubular, the corolla being longer than the calyx and pale red in color. The calyx and corolla are cylindrical, and the corolla is longer than the calyx. The stamens and pistils are long and protruding. The stamens have dark reddish-purple threads and blue anthers.
