Thuja koraiensis ‘Glauca’, commonly known as Korean arborvitae ‘Glauca’, is an evergreen conifer with a broad, elegant conical habit, prized for its distinctive blue-green foliage. Its flattened branches feature a bluish-green upper side and a marked silvery underside, creating a luminous and contrasting effect with the slightest movement of the wind. Its fine texture and naturally structured silhouette make it an excellent choice as a specimen plant, in conifer beds, or as a decorative screen. More tolerant of intense cold than some other arborvitae species, it adapts to fresh, well-drained, and slightly acidic soils. Thuja koraiensis ‘Glauca’ maintains beautiful winter coloration without significant browning, thus offering lasting and refined visual interest in cold-climate landscapes.
