Oriental arborvitae or Oriental thuja typically grows as a dense, conical to columnar, evergreen tree or large shrub to 18-25’ tall. Plants tend to open up with age. Plants have distinctive reddish-brown bark that peels with age. ‘Aurea Nana’ is a dwarf, rounded variety that grows to 5’ tall over the first 10 years. Scale-like golden yellow foliage appears in flattened sprays. Foliage may bronze up in winter. Oval female cones (to 3/4” long) may appear. Platycladus comes from Greek words meaning broad (platys) and branch (klados) in reference to its vertical plane branching configuration. Platycladus orientalis ‘Aurea Nana’ is synonymous with and formerly know as Thuja orientalis ‘Aurea Nana’. ‘Aurea Nana’ is sometimes listed and/or sold under the trade name of BERCKMAN’S GOLDEN ARBORVITAE.
Healthy, well-maintained plants usually have few major problems. Watch for bagworms and spider mites. Scales, aphids, caterpillars, borers and mealybugs may appear. Branches may be broken from snow weight in winter.
