Eastern Arbor-Vitae

Oriental arborvitae brings a quietly unusual geometry to the garden: its flat sprays of foliage arranged in vertical planes rather than the horizontal fans of its western counterparts, giving it a distinctive layered profile that reads well year-round.

Native to northeastern China and Korea, Platycladus orientalis has been cultivated in East Asian gardens for centuries, valued for its dense conical to columnar form and its willingness to grow in conditions that defeat many other conifers. It tolerates heat, drought, alkaline soil, and clay — with the important exception of waterlogged or boggy sites, which it will not forgive. In the landscape it grows 18 to 25 feet tall, developing a broad base in youth that tends to open up and become more irregular with age. The gold and yellow tones in the foliage shift subtly through the seasons, and the leaves emit a resinous scent when bruised.

In practical terms, this is a workhorse screen or hedge plant for zones 6 through 9 in situations where other conifers struggle. Good air circulation helps keep the interior foliage healthy and reduces the conditions that favor spider mites and bagworms, the two pests most likely to cause trouble. Snow and ice can load the branches enough to cause splitting, so in areas with heavy winter precipitation a sheltered site is preferable. The seeds are a reliable food source for small mammals, particularly in the colder months when other options are scarce.
