Spring Grove is a fast-growing western arborvitae selected for a tight pyramidal habit and strong winter foliage color. Glossy dark green sprays remain an important feature in cold weather. Its substantial size and quick growth suit screens and larger evergreen compositions, while the cultivar's documented browsing resistance can be useful where deer pressure is moderate.
