The foliage of Thuja has a pleasant fruity aroma when rubed or a tiny piece crushed. It is tolerant of shade and makes an excellent hedge. Though too big for many gardens there are other species and varieties that are popular with gardeners.
Varieties of Thuja occidentalis, also from north America, are often planted including T. occidentalis ‘Rhinegold’. It grows into a low spreading mound and has golden foliage in sumer which turns a warm rusty colour in winter. Due to its compact growth habit it is often planted in small gardens/
Another variety of T. occidentalis is T. ‘Smaragd’ often sold as T. ‘Emerald’. It can grow to 5 metres high but maintains a narrow columnar habit.
