Thuja koraiensis Glauca Prostrata

Thuja koraiensis ‘Glauca Prostrata’ is a rare, low-growing form of Korean arborvitae selected for its silvery-blue foliage and creeping habit. Native to the mountains of Korea, the species is prized for its cold tolerance and distinctive white undersides, and this cultivar brings those traits into a ground-hugging form. Flattened sprays of blue-green foliage create a soft, textured mat that provides year-round interest. It grows best in full sun to partial shade with evenly moist, well-drained soil and develops slowly. Hardy in USDA Zones 4–7, it remains low and spreading, making it an exceptional choice for rock gardens, slopes, and collector plantings.
