Cupressaceae

Thuja occidentalis ‘De Groot’s Spire’ is a slender western cedar valued for its narrow habit and highly structured columnar silhouette. This evergreen conifer naturally develops a form taller than it is wide, making it ideal for vertical hedges, privacy screens, and linear plantings in confined spaces. Its glossy dark green foliage maintains excellent density year-round and withstands northern climatic conditions well. Narrower than traditional arborvitae, it offers excellent screening power without taking up too much ground space. Hardy and adaptable, Thuja occidentalis ‘De Groot’s Spire’ prefers well-drained soil and a sunny to partially shaded exposure to ensure harmonious growth. It is a reliable choice for structuring landscape designs with elegance and verticality.
