‘Emeraude’ (Smaragd) arborvitae grows as a naturally slender emerald spire reaching 4 m but only 1 m wide, staying bright green even in winter. Excellent for tight screens, entrance flanking or container topiary. Full sun to light shade, moist fertile soil, hardy to −30 °C. No clipping needed—just remove any stray side branch to preserve its jewel‑tone column.
