Cultivars/Varieties

var. hondai - This form is a wide-spreading, large tree with lustrous green, scale-like foliage arranged in dense branchlets. It reportedly grows much larger than the species and features larger cones.

'Aurescens' - Rarely offered, this cultivar sports yellow-gold foliage.

'Nana' (also known as 'Laetevirens') - The most common form in commerce, this plant assumes the proportions of a compact arborvitae. It is a dwarf, mounded plant which slowly reaches 3' tall and is clothed with rough scaly leaves which turn from bright green to bronzy-olive in winter.

'Variegata' - Often seen in the catalogs of specialty nurseries, this novelty form has creamy white regions arranged among the sprays of scale-like foliage. More than one clone probably resides under this name, as the habits of individual plants can vary widely.
