Cedar 'Emerald' ('Smaragd')
FamilyCupressaceae
Thuja occidentalis 'Emerald', also known as 'Smaragd', is a narrow, pyramidal white cedar, highly valued for its lustrous emerald-green foliage, which retains its color all year round, even in winter. Its naturally compact and dense habit makes it an excellent choice for evergreen hedges, specimen plantings, or formal borders. It grows at a slow to moderate rate, without requiring pruning to maintain its shape. Very hardy, tolerant of pruning and urban conditions, it prefers full sun exposure and well-drained soil. 'Emerald' combines neat aesthetics, minimal maintenance, and high landscape value, perfect for creating an elegant and durable structure in any residential landscape.
