Although a slow grower, Thuja is a well-known ornamental American
evergreen; it can reach 70-80 feet, retaining its dense, pyramidal

some references say it is of the pine family. This hardy evergreen
has dense, scale-like foliage, waxy to the touch, and fragrant. Leaves
in flattened sprays; small, appressed overlapping. Cones bell-shaped,
with loose scales.
