Native to northeastern parts of eastern Asia and north Asia.
New spring growth and immature cones on an Oriental arborvitae conifer. The unique looking cones are 15 mm in length and will turn brown over the coming weeks. They are both male (containing the pollen) and female (containing the ova). The pollen from the male cones is transferred to female cones by the movement of the wind and insects through the foliage and then a seed is formed.
