Spring Grove® Western Arborvitae

Spring Grove® is a large, fast-growing western redcedar selected for its dense evergreen form and glossy green foliage. It develops from an open young plant into a tightly conical tree, and published garden references describe it for screening, hedging, and use as a specimen. ## Landscape Use Use Spring Grove® where a substantial evergreen screen or specimen is wanted. Morton Arboretum describes a loose, narrow habit, dark-green foliage with yellow tips, and a 25-foot-by-8-foot garden size; the grower sheet gives a 25–30-foot mature height and notes that it is larger and looser than Emerald Green.

Dawes Arboretum also lists zone 5 and notes that the glossy foliage keeps its green color through winter.

If pruning is needed, avoid cutting into thick stems, which recover slowly; the grower sheet recommends light trimming of new growth for nursery production.
