Thuja occidentalis ‘Degroot’s Spire’ is an evergreen conifer selected for its exceptionally slim, upright form. It grows as a tight vertical column, making it particularly useful where height is needed without width. The fine green foliage forms a dense surface that stays consistent throughout the year, giving the plant a clean, architectural appearance with little maintenance. Because it holds its narrow shape naturally, ‘Degroot’s Spire’ works well as a vertical accent in borders, flanking entrances, or adding structure in small gardens where space is limited. Reliable and restrained, it provides long-term form without demanding regular pruning.
