Family Cupressaceae

Thuja occidentalis 'Golden Smaragd', commonly known as 'Golden Smaragd' American arborvitae, is an evergreen conifer with a narrow, very dense pyramidal habit, valued for its bright golden-yellow foliage. Its vibrant color is particularly intense in spring and early summer, then evolves to a warm golden-green while maintaining a beautiful presence in winter. Its regular and compact silhouette makes it an excellent choice for colorful hedges, privacy screens, or specimen planting in confined spaces. With moderate growth, it naturally maintains a neat shape without excessive pruning. Thuja occidentalis 'Golden Smaragd' prefers fresh, well-drained soil and tolerates both full sun and partial shade. Very hardy, it brings light and lasting structure to cold-climate gardens.
