Golden Smaragd American Arborvitae

Golden 'Smaragd' Western Arborvitae (Thuja occidentalis ‘Golden Smaragd’). The Thuja occidentalis ‘Golden Smaragd’, commonly known as Golden 'Smaragd' Western Arborvitae, is an evergreen conifer with a narrow, very dense pyramidal habit, valued for its bright golden-yellow foliage. Its vibrant coloration 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 plantings in restricted spaces.

To plant Golden 'Smaragd' Western Arborvitae, choose an appropriate exposure: full sun to partial shade. The recommended soil is well-drained, tolerating various soil types. Respect the conifer's natural shape and avoid cutting deeply into parts devoid of foliage. Monitor moisture after planting, including in the fall when the weather is dry. Air circulation and drainage are as important as watering frequency. Water the root ball before planting and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again.

Allow a width of 1 m (3 ft) to arrange this plant's space in the garden. The indicated height of 4 m (13 ft) helps choose its position relative to neighboring plants. Keep access to the base for weeding, checking moisture, and removing damaged parts. Pair this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
