Western Thuja 'Primo'

FamilyCupressaceae

Thuja occidentalis ‘Primo’, commonly known as Primo American arborvitae, is an evergreen conifer with a narrow, pyramidal habit, selected for its exceptional density and rapid growth. It naturally forms a compact column with lustrous dark green foliage, maintaining beautiful coloration throughout the year with a slight bronze tint in winter. Thanks to its uniform and well-structured silhouette, it is an excellent choice for privacy hedges, visual screens, or aligned plantings. Its vigor allows for quickly achieving effective separation while maintaining a controlled width. Thuja occidentalis ‘Primo’ adapts to various types of fresh, well-drained soils and tolerates full sun as well as partial shade. Very hardy, it offers reliability, structure, and lasting privacy in cold climates.
