The Narrow leaved Japanese aucuba (Aucuba japonica f. longifolia) belongs to Cornaceae (the Dogwood family). It is a small evergreen tree that is distributed from Miyagi prefecture in the Tohoku region of Honshu west to Shikoku, Kyushu, Okinawa in Japan, and the Korean Peninsula. It grows in low mountain Japanese cedar forests and thickets, and its height is 0.5 to 3 m. While the leaves of "Japanese aucuba" are oblong, they are usually elongated. Previously, it was used as a cultivar of "Japanese aucuba", but since it seems to grow naturally, it will be changed to one form of "Japanese aucuba". Below the photo are "Japanese aucuba" and "Narrow leaved Japanese aucuba" that grow mingled together.
