DeGroot's Spire Arborvitae is a narrow, upright evergreen conifer with a distinctive columnar structure and lush green leaves. It is an American Arborvitae cultivar chosen for its compact, tall, and slender form, which makes it perfect for landscapes with confined areas. Although generally low-maintenance, trimming may be required to maintain its narrow shape, particularly when young. It typically matures to be 10-15 feet tall and 2-3 feet wide.
