North Pole® Arborvitae

North Pole® is a narrow, upright selection of eastern arborvitae with dense evergreen foliage. Its columnar outline is useful where a year-round screen or vertical evergreen accent is needed. ## Landscape use The [Proven Winners plant profile](https://www.provenwinners.com/plants/thuja/north-pole-arborvitae-thuja-occidentalis) identifies the cultivar as ‘Art Boe’, lists it for zones 3a–8b, and gives USPP 22,174; the [patent record](https://patents.google.com/patent/USPP22174P2/en) supplies the grant date. [Monrovia](https://www.monrovia.com/north-pole-174-arborvitae.html) lists mature dimensions of 10–15 feet tall and 3–5 feet wide; size and growth rate can vary with site and care. Plant it as a specimen, in a narrow screen, or as a vertical accent in a mixed evergreen border. The formal outline also makes it suitable for repeated spacing along property lines or foundations. ## Growing conditions The selection grows in full sun or partial shade. Use a site with room for its mature height and allow airflow around the foliage. Water regularly while it establishes, then adjust irrigation to local soil and weather. ## Maintenance Water consistently during the first growing season and during extended dry periods. Inspect for dead or damaged branches and remove them as needed; routine shaping is generally unnecessary for its naturally columnar habit.
