In the 16 th century in the St. Lawrence Valley of NY, Cartier and his men developed scurvy. The local Indians brewed a tea from the foliage of the native arborvitae and saved their lives.
The oriental arborvitae’s most identifiable feature is the vertical foliage sprays. Look as though they’ve been ironed, or pressed between the pages of a book. They could be spread out and would make a carpet, whereas juniper branches are bushy, not flat, and wouldn’t make a very good carpet.
No buds, like juniper.
Fruit not as berry-like as juniper – has scales that peel back somewhat, sometimes becoming woody.
