Description
Thuja occidentalis 'Silver Smaragd' shrub 25-30 cm C2 | Northern white cedar
Thuja occidentalis 'Silver Smaragd' shrub is a Northern white cedar with an evergreen presence and a distinct, compact form. This product is supplied as a shrub, with an upright, conical silhouette that gives clear structure to a garden throughout the year. Its green to silvery green foliage keeps that outline visible in every season, making the shape an important part of its garden value. The shrub can reach approximately 4 m in height at maturity; no mature width is specified. Its compact growth and conical outline distinguish this shrub from a general description of the species and make it useful where a defined evergreen form is wanted. The name Eastern white cedar is also used locally for Northern white cedar. This cultivar belongs to the Thuja genus. Its foliage, evergreen character and upright outline combine to create a consistent feature in the garden, whether viewed on its own or as part of a planting. The cultivar name is 'Silver Smaragd', and the plant is offered specifically in shrub form. There is no need to rely on flower colour or seasonal flowering for its garden effect: the stated appeal is its persistent foliage and compact, conical shape. This makes it a recognisable evergreen shrub across the seasons.
