Platycladus orientalis
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.
''Platycladus'' is a distinct genus of evergreen coniferous tree in the cypress family Cupressaceae, containing only one species, ''Platycladus orientalis'', also known as Chinese thuja, Oriental arborvitae, Chinese arborvitae, biota or oriental thuja. It is native to northeastern parts of eastern Asia and north Asia, but is also now naturalised as an introduced species elsewhere in Asia.
